Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your particular
application.
WARNING
Hazardous voltages may be present when covers are removed. Qualified
personnel must use extreme caution when servicing this equipment.
Circuit boards, test points, and output voltages also may be floating at a
high voltage relative to chassis ground.
WARNING
The equipment used contains ESD sensitive parts. When installing
equipment, follow ESD Safety Procedures. Electrostatic discharges might
cause damage to the equipment.
Only qualified personnel, who deal with attendant hazards in power supplies, are allowed to perform
installation and servicing.
Ensure that the AC input power line ground is connected properly to the unit safety ground chassis.
Similarly, other AC power ground lines, including those to application and maintenance equipment, must
be grounded properly for both personnel safety and equipment protection.
Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any cable.
In normal operation, the operator does not have access to hazardous voltages within the chassis.
However, depending on the user’s application configuration, HIGH VOLTAGES HAZARDOUS TO
HUMAN SAFETY may be normally generated on the output terminals. The customer/user must ensure
that the output power lines are labeled properly as to the safety hazards and that any inadvertent contact
with hazardous voltages is prevented.
Guard against risks of electrical shock during open cover checks by not touching any portion of the
electrical circuits. Even when power is off, capacitors may retain an electrical charge. Use safety glasses
and protective clothing during open cover checks to avoid personal injury by any sudden component
failure.
AMETEK Programmable Power Inc., San Diego, California, USA, or any of the subsidiary sales
organizations, cannot accept any responsibility for personnel, material or inconsequential injury, loss or
damage that results from improper use of the equipment and accessories.

1. Introduction
This instruction manual contains information on the installation, operation, and calibration of the
Asterion Series power source models with 1-phase output in 1U chassis. The Asterion Series is the
latest generation of switched-mode power sources that provide precise output having high accuracy, low
distortion, and fast dynamic response. With extensive programmability and user interface, it offers a rich
feature set and functionality: AC and DC output capability, wide output frequency range, arbitrary and
harmonic waveform generation, sequencing of transient lists, digital power analyzer measurements,
real-time waveform display, and the capability to be configured in systems comprised of multi-phase and
parallel groups.
Figure 1-1. Asterion Series Front View, 1U Models (With Rackmount Brackets)
1.1 General Description
The Asterion Series power sources are available in 1U chassis at power levels of 500 VA, 750 VA, and
1500 VA. Two AC output voltage ranges are provided, 0-200 VAC/0-400 VAC, with a frequency range of
16 Hz-1200 Hz (with up to 5000 Hz as an option), two DC output ranges, 0-250 VDC/0-500 VDC, and a
combined AC+DC mode. A wide range of AC and DC loads could be powered, including reactive loads
(inductive and capacitive) running at full rated apparent power, and non-linear loads drawing current with
high crest factor, up to 7:1.
The output has an iX2TM constant-power characteristic that provides greater output current at reduced
output voltage: up to 2X at 50% of full-scale voltage. Wide-range AC input is accepted, including
100/115/230/240 VAC, 1-phase/3-phase, and 50/60/400 Hz input frequency. Power factor correction of
the AC input exhibits a sinusoidal current waveform with low input current harmonics. Up to six 1U units
could be connected in parallel or in multi-phase groups, with outputs of up to 9 kVA.
Multiple remote digital communications interfaces are available: standard LAN (Ethernet), USB, and
RS-232C, or the optional IEEE-488 (GPIB) interface. The Asterion Virtual Panels program provides a
convenient graphical user interface, and the SCPI command set allows access to the full
programmability and functionality. Extensive remote analog and discrete digital control interfaces are
also provided for specialized control applications. The front panel display has capability for control,
programming, and measurements of the power source, and features a menu-based interface with
touch-screen data/command entry.
Waveform generation includes standard sine wave and square wave, and extensive programmability to
produce complex waveforms based on harmonics or arbitrary parameter value/time relations. A transient
generator could combine sequences of voltage, frequency, and wave shape to simulate real-world AC or
DC disturbances, and automate a complex profile of power stimulus to the unit under test.
The power analyzer utilizes DSP-based digitization of output parameters to implement measurement
functions spanning single parameter values (voltage/current/frequency), power characteristics
(true/apparent power, crest factor, power factor), and advanced computation using fast Fourier transform
(FFT) derivation of the harmonics and distortion contained in the voltage and current waveforms.
Real-time display of output waveforms is possible through the front panel display or the
Asterion Virtual Panels.

3.2 Mechanical Installation
The Asterion Series power source is designed for rackmount and bench-top applications. It could be
used free standing on a bench top or rackmounted using optional mounting hardware. For bench-top
use, the ship kit contains the four bumper feet for installing to the bottom of the chassis using the
M3-0.5 x 8 mm Philips pan-head screws and 3 mm washers. Rackmounting requires installing the
optional flange brackets with handles to the side of the chassis: using M4-0.7 x 6 mm Philips flat-head
screws to mount the brackets to the chassis, and # 8-32 Philips flat-head screws to mount the handles to
the brackets.
The unit is forced-air cooled with internal fans drawing air in from the front and sides, and exhausting at
the rear. The front and rear of the unit must be kept clear of obstruction and clearance must be
maintained to allow unimpeded airflow. The same consideration given to the side grilles will minimize
internal temperature rise. Special consideration must be made to overall air flow characteristics, and the
resultant internal heat rise, when a source is installed inside enclosed cabinets to avoid excessive
heating and over-temperature problems. The temperature of the ambient air at the air intake should not
exceed 40°C.
WARNING!
This unit is intended for installation in a protected environment. Exposure to conductive
contaminants or corrosive compounds/gases that could be ingested into the chassis
could result in internal damage. Install the power source in a temperature and humidity
controlled indoor area.
CAUTION!
The power source should be provided with proper ventilation. The front and rear of the
unit must be free of obstructions. To ensure proper airflow, a minimum 2" clearance from
the rear air outlet is required.
CAUTION!
No user serviceable parts are inside; service is only to be performed by qualified
personnel.

WARNING!
High voltage present at rear panel poses risk of electrical shock. The input and output
covers must be installed in bench top applications to maintain protection against
hazardous voltages. Do not remove protective covers on AC input or AC/DC output. Refer
installation and servicing to qualified personnel.
WARNING!
The input and output voltages at the rear panel of the unit are HAZARDOUS LIVE. When
rackmounting or panel-mounting the unit, suitable safeguards must be taken by the
installer to ensure that HAZARDOUS LIVE voltages are not operator accessible.
WARNING!
Capacitors in the power source might hold a hazardous electrical charge even if the power
source has been disconnected from the AC mains supply. Allow capacitors to discharge
to a safe voltage before touching exposed pins of mains supply connector.
WARNING!
A safety disconnect device for the AC mains input must be installed so that it is readily
accessible to the operator.
WARNING!
A properly sized input overcurrent protection device must be installed at the AC mains
input. It could be either a circuit breaker or fuse having a rating of 25% over the maximum
AC input line currents listed in the specifications of Section 2.1.4.
WARNING!
To prevent an electrical shock hazard, a safety ground wire must be connected from the
safety-ground stud on the rear panel to the AC mains earth protection-ground
Asterion Series User Manual – 1U Models California Instruments
M330000-01, REV-G 39
3.6 AC Input Connection
The Asterion Series power source is designed to operate from 1-phase or 3-phase input power, having
2-wire/3-wire plus ground, with nominal AC input voltage (line-line or line-neutral) of
100/115/230/240 VAC, and 50/60/400 Hz input frequency. The AC input voltage range is automatically
selected by the unit at power-up; no user setup is required. Power factor correction (PFC) provides high
power factor, minimizing the required input apparent power and current harmonic distortion. Refer to the
specifications of Section 2.1.4 for AC input current requirements, and derating of output power as a
function of AC input voltage.
3.6.1 AC Input Overcurrent Protection
The Asterion Series power source has fuses at the AC input for fault protection. These fuses are internal
to the chassis, and are not user accessible. They provide fault isolation in case a failure occurs of
internal components or wiring. A suitable overcurrent protection device must be provided externally,
within the system installation, to protect the external wiring and interconnects.
3.6.2 AC Input Safety Disconnect Device
The Asterion Series power source front panel POWER switch does not disconnect the AC input line from
the unit. Ensure that an appropriately rated safety disconnect device is incorporated in the installation
that will provide isolation from the AC input when the device is opened. The device could be a switch or
circuit breaker, and must be located close to the unit, within reach of the operator, and clearly labeled as
the disconnection device.
3.6.3 AC Input Connector
The AC input connector, AC INPUT, is located on the rear panel, along with the safety-ground stud.
Figure 3-6 shows the rear panel view of the connector and stud. Table 3-1 shows the functions and
connector pinout, and Table 3-2 lists the connector type. A 1-Phase input is connected to terminals
L1/NEUT or L3/NEUT (do not connect from L1 to L3 to a 1-Phase source), while a 3-Phase input is
connected to L1/L2/L3 (the 3-Phase input is 3-wire plus ground and does not require a neutral
connection). The connector has compression terminals with female contacts. A ground connection must
always be made to the utility earth protection-ground using the rear panel safety-ground stud.
Figure 3-6. AC Input Connector and Safety-Ground
WARNING!
Do not connect to a 3-Phase source (3-wire plus ground) with line-to-line
voltage greater than 264 VAC, or between L1 and L3 to a 1-Phase source.

3.8 Remote Sense
Output voltage sensing is user-selectable to be either local sense or remote sense. Sensing provides the
signal for measurement of the output voltage, and determines the physical point where the output
voltage is precisely regulated. Local sense is at the rear panel output connector, while remote sense is
at the load, through a cable connection from the rear panel remote sense connector. An internal relay is
used to select which sense signal is used by the controller.
Remote sensing is used to compensate for the voltage drop that occurs across the wires connecting the
load to the output of the power source. A separate pair of wires is routed to measure the voltage at the
terminals of the load where precise regulation of the output voltage is desired. The remote sense leads
are connected at the AC/DC Output connector on the rear panel; refer Figure 3-7. Connect the terminal,
Sense LINE, to the point at the load that is connected to the Output LINE terminal, and the terminal,
Sense RTN, to the point at the load that is connected to Output RTN terminal.
Special care is required in routing the sensing leads to prevent noise pickup or coupling to the power
leads; refer to Section 3.9. The sense leads should be a twisted-pair of at least AWG #22 wire, and may
require shielding in high noise environments. If a shield is used, connect it to the functional-ground
terminal at the AC/DC Output connector location.
If the remote sense leads are not connected, but remote sense has been selected, the AC source will
continue to operate but the voltage at the load will no longer be precisely regulated. An internal circuit
exists within the unit that provides redundant voltage sensing from the output terminals, in case the
remote sense leads are not connected. However, this condition does not have voltage calibration, and
since the voltage is now measured at the output terminals, the voltage drop of the load wiring would no
longer be compensated.
Two conditions related to remote sensing are treated as faults and result in shutdown of the output:
short-circuiting of the remote sense terminals or connecting the remote sense leads in reverse polarity.
When the fault condition is detected, shutdown will result with the output voltage being programmed to
zero and the output isolation relays being opened.
3.9 Noise and Impedance Effects
To minimize noise pickup or radiation from load circuits, load wires and remote sense wires should be
twisted-pair and have minimum lead length. Shielding of the sense leads may be necessary in high
noise environments. Even if noise is not a concern, the load and remote sense wires should be
twisted-pairs to reduce coupling between them, which could impact the stability of the output amplifier.
Twisting the load wires provides an additional benefit in reducing the parasitic inductance of the cable.
This improves the dynamic response characteristics at the load by maintaining low source impedance at
high frequencies. If connectors are utilized for the power and sense leads, consideration of routing is
necessary to minimize coupling between the leads. Ensure that the connector terminals for the sense
leads are in adjacent contact locations, and minimize the physical loop area of the untwisted portions.

3.10 Wire Gauge Selection
Care must be taken to properly size all conductors for the input and output of the power source. This
section provides guidance in the selection of wire size.
CAUTION!
Use wire with Class B or C stranding. Fine-stranded (flexible) wire should not be used
unless crimp-on lugs or ferrules are utilized that are approved for fine-stranded cables

The tables below will assist in determining the appropriate wire size for both the input and output
connections. Table 3-5 gives minimum recommended wire size; these recommendations are for 30°C
ambient, and for copper wire only. This table is derived from the National Electrical Code, and is for
reference only. Local laws and conditions may have different requirements. For higher ratings, wires

When determining the optimum cable specification for your power applications, the same engineering
rules apply whether at the input or output of an electrical device. Therefore, this guide applies equally to
the input cable and output cable for this power source and application loads.
Power cables must be able to safely carry maximum load current without overheating or causing
insulation degradation. It is important to power source performance to minimize IR (voltage drop) loss
within the cable. These losses have a direct effect on the quality of power delivered to and from the
power source and corresponding loads.
When specifying wire gauge, consider derating due to operating temperature at the wire location. Wire
gauge current capability and insulation performance drops with the increased temperature developed
within a cable bundle and with increased environmental temperature. Therefore, short cables with
derating of gauge size and insulation properties are recommended for power source applications.
Be careful when using published commercial utility wiring codes. These codes are designed for the
internal wiring of homes and buildings and accommodate the safety factors of wiring loss, heat,
breakdown insulation, aging, etc. However, these codes consider that up to 5% voltage drop is
acceptable. Such a loss directly detracts from the performance specifications of this power source. Also,
consider how the wiring codes apply to bundles of wire within a cable arrangement.
In high performance applications requiring high inrush/ transient currents, additional consideration is
required. The cable wire gauge must accommodate peak currents developed at peak voltages, which
might be up to five times the RMS current values. An underrated wire gauge adds losses, which alter the
inrush characteristics of the application and thus the expected performance.
Table 3-6 presents wire resistance and resulting cable voltage drop at maximum rated current, with the
wire at 20°C. Copper wire has a temperature coefficient of α = 0.00393Ω/°C at t1 = 20°C, so that at an
elevated temperature, t2, the resistance would be R2 = R1 (1 + α (t2 - t1)).
The output power cables must be large enough to prevent the line voltage drop (total of both output
wires) between the power source and the load from exceeding the remote sense capability as presented
in the specification section. Calculate the voltage drop using the following formula:
Voltage Drop = 2 × distance-in-feet × cable-resistance-per-foot × current

The functionality of the Summary Fault (DFI) signal could be programmed through SCPI commands to
report events as captured in either of the following sources: Questionable Status Register (default
setting), Operation Status Register, Standard Event Status Register, or Request Service Summary Bit.
Also, the Summary Fault signal operation could be enabled and disabled through SCPI commands.
Refer to the Asterion Series SCPI Programming Manual, M330100-01, for specific information on the
programming options; it is referred to as the Discrete Fault Indicator (DFI) signal in that manual.
3.11.3 Remote Inhibit Signal
The Remote Inhibit signal, /INHIBIT_ISO (Pin-12), can be used to turn the output on/off and close/open
the output relay of the power source. When set to the off state, this input overrides the output state
programmed through the front panel or the remote digital interface.
The default logic-level for Remote Inhibit is a logic-low or contact closure between /INHIBIT_ISO (Pin-12)
and ISO_COM (Pin-9). This will cause the output voltage to be programmed to zero volts and the output
relays to open. This logic-level could also be selected with the SCPI command, OUTPUT:RI:LEVEL LOW.
Alternatively, the logic-level could be changed by the user to logic-high using the remote digital interface
SCPI command, OUTPUT:RI:LEVEL HIGH. A logic-high or open-circuit between /INHIBIT_ISO (Pin-12) and
ISO_COM (Pin-9) will cause the output voltage to be programmed to zero volts and the output relays to
open.
The mode of operation of the Remote Inhibit can be changed using the remote digital interface SCPI
command, OUTP:RI:MODE <mode>. The following modes can be selected:
LATC(hing) A TTL logic-low (or user-selected logic-high) at the Remote Inhibit input latches
the output in the protection shutdown state; this state could only be cleared by
the remote digital interface SCPI command, OUTPut:PROTection:CLEar.
LIVE The output state follows the state of the Remote Inhibit input. A TTL logic-low
(or user-selectable logic-high) at the Remote Inhibit input turns the output off; a
TTL logic-high (or user-selectable logic-low) turns the output on.
OFF The power source ignores the Remote Inhibit input.
The Remote Inhibit output mode state is saved at power-down. The factory default state is LIVE. For
additional information on programming the Remote Inhibit function, refer to the Asterion Programming
Manual P/N M330100-01 distributed on the CD, CIC496. Refer to AMETEK Programmable Power

3.12 Multiple Chassis System Configurations
The Asterion Series power source has the capability to be configured in multi-chassis groups with
multiple-phase outputs using the optional Clock/Lock signal interface. The sources are individually
programmed for output voltage/current, while the Clock/Lock interface ensures frequency and phase
synchronization between units.
The power source could also be configured in parallel, multiple-chassis groups to extend the total output
power. The outputs of the individual units must be connected in parallel, and a Master/Auxiliary System
interface cable must interconnect them. The control interface of the units is automatically configured
when the Master/Auxiliary System interface cable is connected, so no setting changes by the user are
required.
3.12.1 Multi-Phase System
Refer to Figure 3-16 for the connections that are required to set up a multi-phase group of units; the
example shown is for a 3-Phase system. The output lines, LINE and RTN, are connected independently
from each output of a unit to the load. If the remote sense is used, each unit must have it connected to
the phase of the load at the point where precise regulation of the output voltage is desired.
The units must have the Clock/Lock options installed, with the Master unit having the LKM option and
the Auxiliary units having the LKS option. The Clock/Lock connectors of the Master unit provide output
signals: CLOCK to set the frequency, and LOCK to set the phase. The Clock/Lock connectors of the
Auxiliary units are inputs to accept the control signals from the Master unit. The Clock and Lock
interfaces are signal buses, so the Clock connectors of all units must be connected, and the Lock
connectors must be connected together. Programming, readback, and control are done through the
individual units. Also, the Auxiliary units must have their phase programmed in reference to the Master
unit.
The clock source and configuration must be set for multi-phase operation through the remote digital
interface using SCPI commands or the front panel display. Set up through the front panel is as follows:
1. In the CONFIGURATION, PONS CLOCK CONFIG display menu, the Master unit must have the
configuration set to Master (the AC input must be cycled off/on for a change in a PONS setting
to take effect); refer to Section 4.6.5;
2. In the CONFIGURATION, PONS CLOCK CONFIG display menu, the Auxiliary units must have
the configuration set to Auxiliary (the AC input must be cycled off/on for a change in a PONS
setting to take effect); refer to Section 4.6.5;
3. In the CONFIGURATION, CLOCK MODE display menu, the Auxiliary units must have the clock
source set to External; refer to Section 4.6.5.
Asterion Series User Manual – 1U Models California Instruments
M330000-01, REV-G 55
Figure 3-16. Connections for 3-Phase Master/Auxiliary Group, 1U Models
3.12.2 Parallel System
Refer to Figure 3-17 for the connections that are required to set up a parallel group of units. The output
lines, LINE and RTN, are connected together from each unit to an external terminal block. If the remote
sense is used, only the Master unit has it connected to the load at the point where precise regulation of
the output voltage is desired; the Auxiliary units do not have remote sense connected. The
Master/Auxiliary System Interface cable is connected from the Master unit connector, MASTER, to the
Auxiliary unit connector, AUXILIARY. Additional Auxiliary units are connected from the Master connector
of the last unit in the signal chain to the Auxiliary connector of following unit.
Units of either 750 W or 1500 W rating could be connected in any combination to form a parallel group.
Units with a 500 W rating must be paralleled only to units with the same rating. All programming,
readback, and control are done through the Master unit. The Master/Auxiliary interface is automatically
configured so that the current reported by the Master unit is the sum of all units within the group. The
displays of the Auxiliary units are disabled, and show the message, “SOURCE IN AUXILIARY MODE No
access to the user”.
When the parallel group system is powered up, the order of powering the Auxiliary sources and the
Master source is not important. After the system is powered up, if an Auxiliary power source is powered
down there will be an error message displayed on the Master source, “Aux Down ensure all are powered
up”. If power is reapplied to the Auxiliary source, the message will disappear and normal operation could
resume. If the Master/Auxiliary System Interface cable is removed from the Auxiliary source while the
source is powered down, the error message will disappear, but the Master source will not have the
correct configuration. The Master source must have its AC input power toggled, Off to On, for the correct
configuration to be established.

4.4 Output Power Characteristic
The iX2TM Constant-Power output characteristic of the Asterion power source has a power limit that is
present in each of the two output voltage ranges (low-range and high-range) for AC and DC outputs. Full
rated output power is available from 100% of full-scale output voltage down to 50% of full-scale output
voltage; refer to Figure 4-4 for the relation between the voltage and current follows a constant-power
curve with the limit being the rated power of the unit: The output current increases to 200% of full-scale
output current as output voltage is reduced to 50% of full-scale output voltage. Accordingly, the power
source will automatically adjust the allowed maximum value of the programmed output current when the
output voltage is within 50% and 100% of full-scale to ensure that the power limit is not exceeded. Refer
to graphs for current rating as a function of output voltage and frequency in Figure 2-1 and Figure 2-2.
Figure 4-4. iX2TM Constant-Power Output Characteristic
4.4.1 Front Panel Touch-Screen Display
The front panel display of the Asterion Series power source allows the user to select the various menus
required to configure and operate the unit. Navigating through the various menus could be done using
the touch-screen display or the rotary encoder. Tapping the display screen or clicking with the encoder
on any menu or function that is highlighted (active) will enter that menu or execute that function.
The touch-screen utilizes resistive, pressure-actuated technology, and depends on pressure being
applied to the top surface of the screen to detect the position of input. A fingertip, fingernail, or stylus pen
could be used. To prevent scratching the surface layer, do not use a hard or sharp tip, such as ball-point
pen or mechanical pencil.
.
CAUTION!
Damage or scratching of the touch-screen could occur if excessive pressure is
applied to the surface, or if objects with hard/sharp tips are used.

The rotary encoder can operate in one of two distinct modes:
MODE DESCRIPTION
NAVIGATE The rotary encoder can be used to scroll through menu screen
functions and settings. The current (active) selected item will be
outlined in a highlighted selection-field box. As the encoder is
rotated, the highlighted box will be scrolled through all items on a
screen that could be selected; refer to Figure 4-9.
ADJUST/SELECT After scrolling to a function, the rotary encoder knob is depressed to
select the function (clicking on an item). Clicking on a
selection-button will change its state (on or off), and clicking on a
function or menu will select it and change to a screen that allows
further value entry.
Parameter values, such as voltage and current, are adjusted by
selecting the parameter (clicking on it) to enable the selection-field
(refer to Figure 4-9). If a parameter had been selected whose value
could be adjusted, and the encoder switch is depressed, a screen
will be displayed with a parameter selection-field highlighted that has
a value entry window (refer to Figure 4-10). The rotary encoder could
then be used to continuously adjust the parameter value, up and
down, as the encoder is rotated. Click the encoder a second time to
enter the value. If the OUTPUT switch is on, the output parameter
will change when the encoder is clicked.
The DASHBOARD screen menu has the capability for real-time
adjustment of output parameters: the value of the parameters
change as the rotary encoder is turned for immediate effect at the
output. If the OUTPUT switch is on, the output parameter will change
as the encoder is rotated. Refer to the DASHBOARD screen menu in
Section 4.6.1 for a description of the parameters that have real-time
adjustability.

4.6.1 DASHBOARD Screen Top-Level Menu
The DASHBOARD screen top-level menu is used to change output parameters and simultaneously view
output measurements. The most commonly used output parameters are located in the DASHBOARD
screen menu. The DASHBOARD screen is the default menu that is displayed after power-on.
The top-level menu of the DASHBOARD screen is shown in Figure 4-13. It can be reached in one of two
ways:
1. Tapping DASHBOARD on Home Screen-1 of the front panel touch-screen;
2. Scrolling to DASHBOARD with the encoder and depressing the encoder switch.
The UP arrow button will return back to the previously selected screen menu (in this case the
Home Screen-1). The HOME button will return back to the home screen that has the top-level menu for
the sub-menu being displayed; for the DASHBOARD screen top-level menu, that is the HOME Screen-1.
Figure 4-13. DASHBORD Screen Top-Level Menu
The following selections are available in the DASHBOARD screen top-level menu. Functions that accept
a numeric value require that the value is within the allowed range, otherwise, an error will be generated,
and the value will not be accepted.
Entry Description
Settings
VOLTAGE Programs the output voltage in RMS value, V(RMS), when in
AC-mode and DC-mode, and the AC component when in
(AC+DC)-mode. In (AC+DC)-mode, the DC component is
programmed using the DC OFFSET sub-menu in the OUTPUT
PROGRAM menu. In DC mode, negative values can also be
entered. Real-time setting is possible using the rotary encoder; refer
to Section 4.6.1.1.
CURRENT Programs the output current in RMS value, A(RMS). Real-time
setting is possible using the rotary encoder; refer to Section 4.6.1.1.
FREQUENCY Programs the output frequency in Hz when in AC-mode. If the unit is
in DC-mode, the value for FREQ will be set to DC and cannot be
changed until AC-mode is selected. When in AC-mode, the
frequency can be changed from 16 Hz to 5000 Hz (depending on
options). Real-time setting is possible using the rotary encoder; refer
to Section 4.6.1.1.
VOLTAGE RANGE Selects the 200 VAC or 400 VAC range for AC-mode and
(AC+DC)-mode, and 250 VDC or 500 VDC range for DC-mode
operation. The OUTPUT state must be OFF for a change in range to
be executed.
Asterion Series User Manual – 1U Models California Instruments

Measurements
VOLTAGE Displays the true RMS value of the output voltage measured at the
voltage sense lines (user selectable to be local or remote). In
DC-mode only, the voltage is the DC voltage including polarity.
CURRENT Displays the true RMS value of the output current. In DC-mode only,
the current is the DC current including polarity.
FREQUENCY When in AC-mode or (AC+DC)-mode, the output frequency is
measured at the sense lines. When in DC-mode, this value always
reads “DC”.
4.6.1.1 Real-Time Parameter Adjustment
The DASHBOARD screen menu provides the capability for output parameter entry that has real-time,
immediate effect on the output. This allows manual adjustment of the output parameters where tuning of
a value is desired. Enabling this function requires clicking on a parameter selection-field box with the
encoder switch to select the parameter and display its selection-field highlighted and with a value entry
window (refer to Figure 4-14). The rotary encoder could then be used to continuously adjust the
parameter value, up and down, as it is rotated. The value change takes immediate effect at the output.
Figure 4-14. Real-Time, Immediate Output Parameter Adjustment
4.6.1.2 Default Screen
The Default screen provides measurement of the RMS output voltage and current; refer to Figure 4-15.
Initially, it appears after power-on if it has been enabled to do so in the configuration setup (user
selectable; refer to Section 4.6.5). Subsequently, when in the Dashboard screen, and idle for an interval
equal to a set time delay, the display will automatically switch to the Default screen. The Default screen
could also be selected from the MEASUREMENTS screen; refer to Figure 4-17. Tap anywhere on the
screen, including the Up arrow, to return to the Dashboard screen; tap the Home icon to return to the
HOME Screen-1. Refer to Section 4.6.5 for setup of the Default screen.

The following choices are available in the OUTPUT PROGRAM screen top-level menu. Functions that
accept a numeric value require that the value is within the allowed range, otherwise, an error will be
generated, and the value will not be accepted.:
Entry Description
Settings
VOLTAGE Programs the output voltage in RMS value, V(RMS), when in
AC-mode and DC-mode, and the AC component when in
(AC+DC)-mode. In (AC+DC)-mode, the DC component is set
separately using the DC OFFSET selection-field (below), or through
the Dashboard screen. In DC-mode, negative values can also be
entered. The default is zero.
Asterion Series User Manual – 1U Models California Instruments
76 M330000-01, REV-G
CURRENT Programs the output current in RMS value, A(RMS). The default is
full-scale for the model.
VOLTAGE RANGE Selects the 200 VAC or 400 VAC range for AC-mode and
(AC+DC)-mode, and 250 VDC or 500 VDC range for DC-mode
operation. The output must be turned off for a change in range to be
executed. The default is low-range, 200 VAC.
FREQUENCY Programs the output frequency in Hz when in AC-mode. If the unit is
in DC-mode, the value for FREQ will be set to DC and cannot be
changed until AC-mode is selected. When in AC-mode, the
frequency can be changed from 16 Hz to 5000 Hz (depending on
options). The default is 60 Hz.
DC OFFSET Programs the DC offset value, V(DC), when in the (AC+DC)-mode;
entries with positive and negative polarity are allowed. The AC
component of the output voltage is set separately using the
VOLTAGE selection-field (above) or through the Dashboard screen.
In AC-mode and DC-mode, this function is not available, and the
function is listed as “N/A”. The default is zero.
AC/DC Selects the mode of operation of output voltage: either AC only, DC
only, or AC with a DC offset, AC+DC. This selection also determines
the available output voltage ranges: 200/400 V(RMS) in AC and
AC+DC modes, and 250/500 VDC in DC mode. The output must be
turned off to change this setting. The default is AC.
Asterion Series User Manual – 1U Models California Instruments
M330000-01, REV-G 77
OVP Programs the Overvoltage Protection (OVP) threshold for the output
voltage. Exceeding the OVP threshold will result in shutdown of the
output, with the output isolation relay opened and the output voltage
programmed to zero. The maximum OVP setpoint is 115% of
full-scale low-range/high-range output voltage: AC-Mode and
(AC+DC)-mode, 230V/430V; DC-Mode, 287.5V/575V. The default
value is 115% of full-scale.
PHASE Programs the phase angle of the output voltage: in a standalone
unit, the phase angle would be with respect to the external SYNC
signal; in an Auxiliary unit (with LKS option) of a multi-phase group,
the phase angle would be with respect to Phase-A, while Phase-A
would be the reference at 0°. If the clock source is selected to be
internal, this parameter has no effect. The default is zero.
WAVEFORM Selects the waveform for the output voltage: either standard
waveforms for sine wave, square wave, or clipped-sine wave; or,
user-defined waveforms. The default is sine wave.
The standard waveforms are always available, and do not consume
any of the user-defined waveform memory registers; they are always
displayed in the waveform list. The clipped-sine waveform has a
waveform where the peak amplitude of the positive and negative
alternation is clipped (flattened appearance). The level of clipping is
dependent on the amount of harmonic distortion present in the
output waveform. An additional programmable parameter,
CLIP % THD, is available for setting the percentage of total
harmonic distortion (THD); the range is 0-43%.
The user-defined waveforms could be selected from up to fifty
waveforms in one of four groups (group 0-3, totaling 200 waveforms)
that are active. The waveform group that is active at power-on of the
unit could be selected with the SCPI command,
PONSetup:WGRoup <n>, through the digital interface. For
information on generating user-defined waveforms and their
selection, refer to the Asterion Virtual Panels or the Asterion Series
Programming Manual P/N M330100-01 (distributed on the CD,
CIC496), or refer to the AMETEK Programmable Power website,
www.powerandtest.com, to download latest versions.
Asterion Series User Manual – 1U Models California Instruments
78 M330000-01, REV-G
Time Domain selection-field: This function displays the voltage
waveform in the time domain (oscilloscope function). This function is
active for user-defined waveforms, but not for standard waveforms.
The units of the horizontal axis are in degrees and of the vertical axis
in fraction of full-scale value. The waveform is scaled to fit the
viewing area. The upper right-side corner shows parameter data
(fraction of full-scale and phase angle) of the point on the waveform
selected by the yellow cursor. A zoom function is available to
observe the waveform in more detail. Refer to Section 6.2.3 for
detailed information on using the cursor and zoom function.
Harmonic Analysis selection-field: This function displays the
frequency spectrum of the voltage waveform derived through FFT
(fast Fourier transform) analysis. This function is active for
user-defined waveforms, but not for standard waveforms. The
frequency spectrum is displayed in graphical format, ranging from
DC through the 50th harmonic. Individual harmonics could be
selected (shown with triangle along horizontal axis) to display their
parameter data using the Right and Left arrow buttons, touchscreen, or encoder. The upper right-side presents the data for the
selected harmonic: harmonic number, frequency, percentage of
fundamental, and phase angle).
REGULATION Selects options for regulation of the output voltage: whether ALC is
enabled, and what control action will be performed when the load
current reaches the current setpoint. The defaults are CV/CL, with
Delay of 0.2 seconds and ALC on.
Asterion Series User Manual – 1U Models California Instruments
M330000-01, REV-G 79
Constant-Voltage/Constant-Current (CV/CC): CV/CC mode will
regulate the output voltage to the set value until the load current
reaches the current setpoint; after the Delay interval, if the current
exceeds the setpoint, the output current will be controlled to equal
the setpoint. Regulation of the load current is accomplished by
reducing the output voltage as needed to satisfy the load. As such,
the voltage could be reduced from the set value down to zero,
depending on the load requirement. This mode is useful for starting
up motor or capacitor loads that may require a high inrush current.
In constant-voltage mode of operation, the waveform and
instantaneous amplitude of the output voltage is regulated to equal
the programmed values; if Volt ALC is enabled, the RMS value is
also precisely regulated. In constant-current mode of operation, the
RMS value of the output current is regulated to equal the
programmed value. However, this is accomplished by controlling the
voltage amplitude and waveform, and not directly the current;
therefore, the current instantaneous amplitude and waveform and
dependent on load characteristics.
Constant-Voltage/Current-Limit (CV/CL): CV/CL mode will
regulate the output voltage to the set value until the load current
reaches the current setpoint; after the Delay interval, if the current
equals or exceeds the setpoint, a fault condition will be generated,
and the output voltage will be programmed to zero and the isolation
relay opened. This effectively turns off the AC source output in case
of an overload condition, after the user-programmable trip
time-delay.
Delay: Sets the time duration that the output current could equal or
exceed the current setpoint before control action is taken. After the
delay, if CV/CC mode is selected, the output current will be
regulated to its setpoint; if CV/CL mode is selected, an overcurrent
fault condition will be generated and the output will be turned off.
The Delay is programmable from 0.1-5 seconds.
Volt ALC: Volt ALC selects whether the automatic loop control,
ALC, is enabled. ALC provides improved output regulation and
accuracy by regulating the RMS value of the output voltage through
action of a digital regulator that measures the output voltage and
controls it to equal the setpoint.
ON: ALC is enabled; regulation is accomplished through the
RMS digital regulator; if the RMS digital regulator exceeds its
control capability and could not maintain regulation, the output
will be shut down and a fault condition will be generated with
the output turned off and the voltage programmed to zero;
REG: ALC is enabled; regulation is accomplished through the
RMS digital regulator; if the RMS digital regulator exceeds its
control capability and could not maintain regulation, the output
will remain on, but the voltage will deviate from the setpoint,
and a fault condition will not be generated;
OFF: ALC disabled; regulation is accomplished without use of
the RMS digital regulator, and shutdown that is dependent on
loss of regulation will not occur.

4.6.3 MEASUREMENTS Screen Top-Level Menus
The Asterion Series power source uses a DSP-based data acquisition system to provide extensive
information regarding the output parameters. This data acquisition system digitizes the voltage and
current waveforms and calculates parameter values from the data. The result of these calculations is
displayed in a series of measurement data screens. The actual digitized waveforms can also be
displayed by selecting the Trace Capture screen. The MEASUREMENTS screen top-level menu is used
to display the results of output parameter measurements, harmonics analysis, and output waveforms.
The top-level menus of the MEASUREMENTS screens are shown in Figure 4-17. They can be reached
in one of two ways:
1. Tapping MEASUREMENTS on Home Screen-1 of the front panel touch-screen;
2. Scrolling to MEASUREMENTS with the encoder and depressing the encoder switch.
The UP arrow button will return back to the previously selected screen menu (in this case the
Home Screen-1). The HOME button will return back to the home screen that has the top-level menu for
the sub-menu being displayed; for the MEASUREMENTS screen top-level menus, that is the
HOME Screen-1.

The following functions are available in the menus of the MEASUREMENTS screen:
Entry Description
GROUP MEASUREMENTS Displays the following output parameters together on one screen:
RMS voltage, RMS current, frequency, real power, apparent
power, and power factor
.
FREQUENCY When in AC-mode or (AC+DC)-mode, displays the output
frequency. In the DC-mode, this value always reads “DC”.
POWER Displays the true power, kW, and apparent power, kVA, of the
load.
VOLTAGE Displays the true RMS value of the output voltage measured at
the voltage sense lines (user selectable to be local or remote). In
DC-mode only, the voltage is the DC voltage including polarity.
CURRENT When in AC-mode or (AC+DC)-mode, displays the RMS output
current. In the DC-mode, displays the DC current including
polarity. The Peak Current displayed is the maximum
instantaneous value that has been detected. The Reset function
allows resetting the peak value to zero and restarting current
tracking. The peak current measurement will continuously track
the maximum current value detected until reset.
Asterion Series User Manual – 1U Models California Instruments
82 M330000-01, REV-G
PHASE Displays the phase angle of the output of the power source: in a
standalone unit, the phase angle would be with respect to the
external SYNC signal; in an Auxiliary unit (with LKS option) of a
multi-phase group, the phase angle would be between the Auxiliary
output and the Master output. If the clock source is selected to be
internal, this parameter is not used.
POWER FACTOR Displays the power factor of the load.
WATT HOUR Displays the energy, kWh, consumed by the load, and the true
power in kW. The Start and Stop function determine the interval
during which energy is calculated. The Clear function resets the
accumulated energy value.
VOLTAGE THD Displays the total distortion of the output voltage. The distortion
calculation is based on the harmonics voltages, H2 through H50,
relative to the total RMS value of the voltage. Another common
definition of THD calculates the harmonics relative to the value of the
fundamental voltage H1. There might be a difference in results
depending on the harmonic content. The method is selectable over
the digital interface with the SCPI command, MEAS:THD:MODE
<value>, with the value being either RMS (relative to total RMS) or
FUND (relative to fundamental).
CREST FACTOR Displays the crest factor of the output current as the ratio of its peak
value to its RMS value.
Asterion Series User Manual – 1U Models California Instruments
M330000-01, REV-G 83
CURRENT THD Displays the total distortion of the output current. The distortion
calculation is based on the harmonics currents, H2 through H50,
relative to the total RMS value of the current. Another common
definition of THD calculates the harmonics relative to the value of the
fundamental current H1. There might be a difference in results
depending on the harmonic content. The method is selectable over
the digital interface with the SCPI command, MEAS:THD:MODE
<value>, with the value being either RMS (relative to total RMS) or
FUND (relative to fundamental).
HARMONICS Displays harmonic content of voltage and current waveforms derived
from an FFT analysis. The amplitude and phase of harmonics up to
the 50th (bandwidth limited) are calculated and displayed.
Figure 4-18. HARMONICS Menu
The HARMONICS menu has the following fields:
Entry Description
FUNCTION HARMONICS menu: Selects Voltage or Current for display.
VIEW HARMONICS menu: Selects display modes, as follows:
Table: Displays the first 50 harmonics (bandwidth limited) in a
tabular text format, shown below;
Bar: Displays the first 50 harmonics (bandwidth limited) in a
graphical bar chart display, shown below.
DATA HARMONICS menu: Selects absolute or relative harmonics
display for TABLE and BAR view modes. In relative mode, all
harmonics are shown in a percentage of the fundamental which
is normalized at 100%. In absolute mode, the harmonic
amplitudes are shown in absolute volts or amperes.
Asterion Series User Manual – 1U Models California Instruments
84 M330000-01, REV-G
MODE HARMONICS menu: Selects the trigger mode for the
acquisition, as follows:
SINGLE: Single-shot acquisition; in this mode, the acquisition is
triggered once each time the START field is selected. The
selected trigger source is used to determine the trigger point.
Once the acquisition has been triggered, the data are displayed
and do not change until the next acquisition is triggered. This
mode is most appropriate for single-shot events, such as
startup currents.
CONTINUE: Continuous acquisition; in this mode, acquisitions
occur repeatedly and the data is updated on screen after each
trigger occurrence. This provides a continuous update of the
data, and is most appropriate for repetitive signals.
SOURCE HARMONICS menu: Selects the event that will trigger a
measurement acquisition, as follows;
IMMEDIATE: Causes the acquisition to trigger immediately
when the START field is selected. This is an asynchronous
trigger event. The acquisition will always be triggered in this
mode and data is available immediately.
PHASE: Causes the acquisition to trigger on the occurrence of
zero phase angle of the output voltage. When started, the
acquisition holds until the zero phase angle occurs, before
triggering the acquisition. This mode allows exact positioning of
the acquisition data window with respect to the voltage
waveform.
DELAY HARMONICS menu: Selects the time delay to position the
trigger point relative to the acquisition window. A negative value
will provide pre-trigger information on data leading up to the
trigger event. The pre-trigger delay cannot exceed the length of
the acquisition buffer; see Section 6.4.3 for details. A positive
trigger delay positions the data window after the trigger event.
Positive trigger delays can exceed the length of the acquisition
buffer in which case the trigger event itself will not be in the
buffer any more. The maximum value of the trigger delay is
1000 ms. The default trigger delay value is 0.0 ms which puts
the trigger event at the beginning of the acquisition window.
START HARMONICS menu: Starts a new acquisition run. When the
start field is selected, and after the trigger event occurs, the
display changes to the data display mode that was selected in
the VIEW field of the HARMONICS menu; refer to Figure 4-18.
To return to the HARMONICS menu, tap the HOME button
while in the data display screen.

4.6.4 TRANSIENTS Screen Top-Level Menu
The Asterion Series power source provides the capability of generating custom waveforms through
programming the output in a sequence of steps in a list of transients. The steps could be comprised of
combinations of changes in voltage, frequency, phase angle, waveform, and duration. The list could be
created, run and stored through either the front panel, or the remote digital interface using the Asterion
Virtual Panels program or SCPI commands. A library of lists could be produced and stored in memory of
the power source for quick recall and utilization through use of SCPI commands or the Asterion Virtual
Panels. Refer to the Asterion Series Programming Manual P/N M330100-01 (distributed on the CD,
CIC496), or refer to the AMETEK Programmable Power website, www.powerandtest.com, to download
latest versions.
The TRANSIENTS Screen provides access to the transient list data. A transient list of up to 100 data
points is possible, represented by 100 transient step numbers from 0 through 99.
The top-level menu of the TRANSIENTS screen is shown in Figure 4-24. It can be reached in one of two

Figure 4-25. SETTINGS Menu
The SETTINGS menu has the following fields:
Entry Description
T(ime) Sets the units for time of the transient step; the default units are in
seconds. Alternately, the time could be changes to cycles of the
output frequency. Note that time durations in seconds may result in
rounding errors if the period of the programmed frequency is not an
integer number of milliseconds. For example, for 50 Hz output
(20 ms period), no rounding errors occur, but for 60Hz (16.66 ms
period) a rounding error would occur when converted. The time
duration scale selection affects both the Time and End Delay
parameters.
V(oltage) Sets the units for voltage values; the default units are in V(RMS). V
is the RMS value of the output voltage, while % is the percentage of
the steady-state setting.
F(requency) Sets the units for frequency values; the default units are in Hz. Hz is
the value of the output frequency, while % is the percentage of the
steady-state setting.
Start Phase Shows the start phase angle of the voltage transient in degrees.
Only one start phase angle per transient sequence is allowed. The
start phase angle must be in the first transient event of the list. The
start phase angle is not valid for DC transients.
Step Defines how the step sequence of the transient list is executed; the
default is All:
All: All of the steps in the sequence are executed without breaks;
Single: Each step is executed one at a time.

The ADD sub-menu has the following fields:
Entry Description
DROP Causes the output voltage to go to zero volts for a specified period of
time. As with the step transient, the voltage change is instantaneous.
At the end of the drop, the voltage will return to the amplitude at the
beginning of the step.
VOLTAGE SWEEP/STEP VOLTAGE SWEEP causes the output voltage to change from the
present value to a specified end value at a specified rate of change,
while a VOLTAGE STEP causes an instantaneous change in output
voltage. The new value will be held for the specified time duration.
The final output voltage value of a sweep and a step transient step
should be different than the value at the start of the transient step, or
no change in output voltage will occur.
VOLTAGE SURGE/SAG VOLTAGE SURGE and SAG are temporary changes in
amplitude. The output voltage will change from its present value
to a specified value for a specified duration. Surge is a change to
a higher value, while sag is a change to a lower value. After the
time duration has expired, the output voltage returns to a
specified end value. This value could be the same or different
from the value present prior to the start of the surge or sag.
FREQUENCY SWEEP/STEP FREQUENCY SWEEP causes the output frequency to change
from the present value to a specified end value at a specified rate
of change, while a FREQUENCY STEP is an instantaneous
change in output frequency. The new value will be held for the
specified time duration. The final output frequency value of a
sweep and a step transient step should be different than the
value at the start of the transient step, or no change in output
frequency will occur.
