1. Introduction
This instruction manual contains information on the installation, operation, and calibration of the
Asterion Series power source models with 1-phase/3-phase output in a 14U 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 respons e. With extensive programmability and user interf ace,
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 t he capability to be configured in systems comprised of
multi-phase and parallel groups.

1.1 General Description
The Asterion Series power sources are available in a 14U chassis at power levels of 12000 VA and
18000 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 5:1.
TM
iX2
The output has an
output voltage: up to 2X at 50% of full-scale volt age. The Asterion 14U models support two types of AC
inputs, one type being 200-240 VAC, 3-phase, 3-wire plus ground, and the other being
220/380 VAC - 240/415 VAC, 3-phase, 4-wire (with neutral) plus ground. AC input frequency is either
50/60 Hz. The Asterion 14U models provide power factor correction of the AC input with low input current
harmonics, producing PF of 0.95/0.98, 3-wire/4-wire. Two 14U units can be connected in parallel or in
multi-phase groups, with outputs of up to 36 kVA.
Multiple remote digital communications interfaces are available: standard LAN (Ethernet), USB, and
RS-232C, or the optional IEEE-488 (GPIB) interface. The Ast erion Virtual Panels GUI program provides
a convenient graphical user interface, and t he 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 application s. The front panel display has capability for control,
programming, and measurements of the power source, and features a men u-based interface with
touch-screen data/command entry.
constant-power characteristic that provides greater output current at reduced
Waveform generation includes standard sine wave and square wave, and extensive programmability to
produce complex waveforms based on harmonics or arbitrary parameter value/time relationships. A
transient generator could combine sequences of voltage, frequency, and wave shape to simul ate
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 param eters to implement measurement
functions spanning single parameter values (voltage/current /f requency ), power characteristics
(true/apparent power, crest factor, power factor), and advanced computation using fast Fourier transform
(FFT) derivation of the harmonics and di st ort i on contained in the voltage and current waveforms.
Real-time display of output waveforms is possible thr ough the front panel display or the
Asterion Virtual Panels GUI.

Constant-Power Mode Output Characteristic
The iX2TM Constant-Power mode has an output characteristic where full rated output power is available
from 50% of full-scale output voltage to 100% of full-scale output voltage, as depicted in the graph of Figure
2-1. The output current versus output voltage follows a constant-power relation where the output current
would be 200% of the full-scale value when t he output volt age is 50% of full-scale. The current ratings are
also a function of output frequency, as shown i n Figure 2-1 above 500 Hz for the AST12K3 and AST18K3
units.

WARNING!
High voltage present at rear panel poses risk of electrical shock. The input, output, and
sense covers must be installed in standalone applications to maintain protection again st
hazardous voltages. Do not remove protective covers on AC input, AC/DC output, or
output sense. Refer installation and servicing to qualified personnel.
WARNING!
The input and output voltages at the rear panel of the unit are HAZARDOUS LIVE. When
rack 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 hazard ous 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 m ai ns s uppl y 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 devi ce must be installed at the AC mains
input. It could be either a circuit breaker or fuse having a rating of 25% over t he m aximum
AC input line currents listed in the specifications of Section 2.1.3.

3.9 Remote Sense
Output voltage sensing is user-sele ct able 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 controlle r.
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 t he out put voltage is desired. The remote sense leads
are connected at the Remote Sense connector on the rear panel; refer Figure 3-14. Connect the
terminals, Sense Phase-A/B/C, to the points at the load that are connected to the Out put Phase-A/B/C
LINE terminals, and the terminal, Sense RTN, to the point at the load that is connected to Output RTN
terminal. For 1-phase mode of operation, connect only the Sense Phase-A to t he l oad.
Special care is required in routing the sensing leads to prevent noise pickup or coupling to the power
leads; refer to Section 3.10. 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 l onger be precisely regulated. An internal circuit
exists within the unit that provides redundant v oltage sen sin g from the output t erminals, in case the
remote sense leads are not connected. However, this condition does not have voltage calibrat i on, and
since the voltage is now measured at the output termi nal s, t he voltage drop of the load wiring would no
longer be compensated.
Two conditions related to remote sensing are treat ed 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.
3.10 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-pai rs to
reduce coupling between them, which could impa ct t he stabi l i t y of the output amplifier. Twisting the load
wires provides an additional benefit in reducing the parasitic inductance of the cable. This improves t he
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 t he physical loop area of the untwisted portions.

When determining the optimum cable specificati on for your power applications, the same engineering
rules apply whether at the input or output of an electrical device. Therefore, this guide applies equally t o
the input cable and output cable for this power source and application loads.
Power cables must be able to safely carry maxim um l oad current without overheating or causing
insulation degradation. It is important to power source performance t o m i ni m ize 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 utilit y 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, t hese 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 wit hi n a cable arrangement.
In high performance applications requiring high inrush/ transient currents, additional conside ration 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 3-10 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 f rom exceeding the remote sense capability as pre sent ed
in the specification section. Calculate the vol tage drop using the following formula:
Voltage Drop = 2 × distance-in-feet × cable-resistance-per-foot × current

3.12.2 Summary Fault Signal (DFI)
The Summary Fault (DFI) signal, SUMMARY FAULT-1 (Pin-14) and SUMMARY FAULT-2 (Pin-15),
provides an indication of abnormal conditi on occurrence. In the default configuration, the signal reports
the summary bit that is the logic-OR of the Questi onable Status Register outputs for the following ev ents:
a. PFC Module fault: summary state of overtemperature, input undervoltage, overload;
b. DC Module fault: summary state of overtemperature, output overvoltage, driver fault;
c. AC Module fault: summary state of overtemperature, DC bus under/overvoltage, inverter
peak current limit, logic power undervoltage;
d. Overtemperature fault: AC Module overtemperature, PFC Module Over temperature, DC-DC
Module Over temperature;
e. Output overvoltage fault;
f. Output voltage regulation fault;
g. Output current-limit fault.
h. Fan Fault
The functionality of the Summary Fault signal co ul d be programmed through SCPI commands to report
events as captured in either of the following sources: Quest i onable 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 an d di sabled through SCPI commands. Refer to the
Asterion Series SCPI Programming Manual, M3301 00-01, for specific information on the programming
options; it is referred to as the Discrete Fault Indicato r (D F I) signal in that manual.
3.12.3 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 t he of f state, this input overrides the output state
programmed through the front panel or the remote digital interface.
The default logic-level for Remote Inhi bit is a l ogi c-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 c ould al so be s elect ed wit h the S CPI com ma nd, 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 t urns the output off; a TTL

3.12.4 External Relay Interface
The External Relay Interface rear panel connector is shown in the Figure 3-16, Table 3-14 shows
connector type, and Table 3-15 shows the connector pinout.
The External Relay Interface provides a control signal interface with an isolated relay contact to indi cat e
the 1-Phase output mode of operation; refer to Figure 3-17 for an example of utilization of the signal
interface, and note the following considerations r eferenced in the figure:
1. The External Relay Interface relay contacts could be used to control an external relay that would
connect together the three output lines (Phase A/B/C) when the unit is set for 1-Phase output
mode of operation. This provides a means to automatically change the output configuration
between 3-Phase and 1-Phase modes.
2. The return terminals (RTN) are connected together internally in the unit, but for total load curre nt
greater than 60 A in the return, use individual wir es f rom each of the RTN terminals to the load
and connect them together externally.

3.13 Multiple Chassis System Configurations
The Asterion Series power source has the capability t o be conf i gured 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.
3.13.1 Multi-Phase System
The connections to set up a multi-phase group of units require that the output lines, PHASE-A,
PHASE-B, PHASE-C, and RTN, are connected independently from each o ut put of a unit to the load. If
the remote sense is used, each unit must have it connect ed 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 conne ct ors 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 t he M aster 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. P rogramming, readback, and control are done through the
individual units. Also, the Auxiliary units must have their phase programmed in reference to the Master
unit. Refer to Figure 3-26 for an example configuration.
The clock source and configuration must be set for m ulti-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.
3.13.2 Parallel System
The connections to set up a parallel group of units requi re t hat the output lines PHASE-A, PHASE-B,
PHASE-C 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 unit does not have remote sense connected. The
Master/Auxiliary System Interface cable is conne ct ed from the Master unit connector, MASTER, to the
Auxiliary unit connector, AUXILIARY. Refer to Figure 3-25 for an example configuration.
The aggregate output power of the parallel group would be sum of the individual ratings of the 14U
Asterion Series models connected in parallel. M aximum aggregate power allowed by paralleling 14U
Asterion power sources is limited to 36 kW.
M330511-01, REV-B 65
Asterion Series User Manual – 14U Models California Instruments
The Master/Auxiliary interface is automat icall y configured so that the current reported by the Mast er unit
is the sum of all units within the group. The display of the Auxiliary unit is disabled, and shows 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 source 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 M aster 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 Interf ace cable is removed from the Auxiliary source while t he
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 re-established.

16. Turn off the OUTPUT switch.
17. Switch on the resistive load to each phase that is set to draw 90% of full-scale current at 400
V(RMS) for the high-range AC output.
18. Repeat Steps 7 through 11, but set the AC output of each phase for the following:
voltage range = high, 400 V; output voltage = 400 V(RMS); current setting = full-scale for
particular model being tested.
19. Repeat Steps 5 through 18, but set the output of each phase for DC mode operation with the
voltage set for 250 VDC in the low-range and 500 VDC in the high range, and the load for each
phase set appropriately for the DC range selected.
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. Ful l
rated output power is available from 100% of ful l-scal e output voltage down to 50% of full-scale output
voltage; refer to Figure 4-3 for the relation between the voltage and current follows a constant-power
curve with the limit being the rated power of the unit: The out put 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.

4.5 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 don e using
the touch-screen display or the rotary encoder. Tapping the di splay 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 p osition 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 t ips are used.
The present cursor position is always shown with a selection-box that has a highlighted border around a
field. Some screens have multiple pages, as indicate d by the highlighted Arrow icons located on the right
side of the screen: for example, the default HOME Screen can be scrolled through three pages. Tapping
an Arrow or selecting it with the rotary encoder and clicking the switch, scrolls the screen to the next
page. When outside one of the HOME screens, tapping the Home icon will exit that screen and return
back to the HOME screens. Refer to Figure 4-4.
Figure 4-4. HOME Screen
Parameters that are adjustable have selection-fields where values could be entered. The parameter
selection-field that is active has its border highlighted; refer to Figure 4-5 where the Dashboard Menu i s
shown with the voltage selection-field active. Tapping the selection-field box, selects that parameter for
adjustment, and the screen changes to the numeri c k eypad that allows value entry; refer to Figure 4-7.

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-fiel d hi ghl ighted that has a
value entry window (refer to Figure 4-10). The rotary encoder could
then be used to continuously adjust the parameter v alue, up and
down, as the encoder is rotated. Click the encoder a second time to
enter the value. If the OUTPUT switch is on, t he 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 pa rameters change
as the rotary encoder is turned for immediate effect at t he out put. 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

M330511-01, REV-B 85
Asterion Series User Manual – 14U Models California Instruments
PHASE Programs the phase angle of the output voltage in a standalone unit
operating in 1-Phase configuration; 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.
In a 3-Phase configuration, programs the Phase-B and Phase-C with
respect to the Phase-A reference.
DC OFFSET Programs the DC offset value, V(DC), when in the (AC+DC)-mode;
entries with positive and negative polarity are all owed. The AC
component of the output voltage is set separately u sing 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.
VOLTAGE RANGE Selects the 200 VAC or 400 VAC rang e f or 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.

Asterion Series User Manual – 14U Models California Instruments
VOLTAGE MODE 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 i s A C.
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 wave form 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 paramet er, CLIP % THD, is
available for setting the percentage of total harmo nic distort io n
(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 i nterface. For
information on generating user-defined waveforms and their
selection, refer to the Asterion Series Programmi ng Manual
P/N M330100-01 (distributed on the CD, CIC496) or the Asterion
Virtual Panels GUI; refer to AMETEK PPD website,

START PHASE A Programs the phase angle of the output voltage at which Phase-A
will begin generating an output. The default is 0°.
M330511-01, REV-B 87
Asterion Series User Manual – 14U Models California Instruments
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.
Constant-Voltage/Constant-Current (CV/CC): CV/CC mode will
regulate the output voltage to the set value until the l oad 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 regulat ed 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 ampl itude 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 t he l oad 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 userprogrammable trip time-delay.
Delay: Sets the time duration that the output current could
equal or exceed the current setpoint before contr ol action is
taken. After the delay, if CV/CC mode is selected, t he 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 programm able 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.
88 M330511-01, REV-B
Asterion Series User Manual – 14U Models California Instruments
ON: ALC is enabled; regulation is accomplished t hrough 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 ze ro;
REG: ALC is enabled; regulation is accomplished t hrough 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 screen s. 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 measur ements, 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 of t he f ront 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). 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 m enus, that is the HOME Screen.

the voltage sense lines (user selectable to be local or remote). In
DC-mode only, the voltage is the DC voltage including polarity.
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.
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 – 14U Models California Instruments
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 (wit h 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.
CREST FACTOR Displays the crest factor of the output current as the ratio of its peak
value to its RMS value.
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 r esets t he
accumulated energy value.

Asterion Series User Manual – 14U Models California Instruments
CURRENT THD Displays the total distortion of the output current. The distortion
calculation is based on the harmonics currents, H2 t hrough H50,
relative to the total RMS value of the current. Anot her common
definition of THD calculates the harmonics relative t o the value of the
fundamental current H1. There might be a difference in results
depending on the harmonic content. The method is selectabl e over
the digital interface with the SCPI command, MEAS:THD:MODE
<value>, with the value being either RMS (relativ e to total RMS) or
FUND (relative to fundamental).
VOLTAGE THD Displ ays the total distortion of the output voltage. The dist ort i on
calculation is based on the harmonics voltages, H 2 through H50,
relative to the total RMS value of the voltage. Another common
definition of THD calculates the harmonics relative t o the value of the
fundamental voltage H1. There might be a difference in results
depending on the harmonic content. The method is sel ectabl e over
the digital interface with the SCPI command, MEAS:THD:MODE
<value>, with the value being either RMS (relati ve 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 ha rmonics up to
th
the 50
(bandwidth limited) are calculated and displayed.

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.
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 t he 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 continuou s 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 trigge red 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, t he
acquisition holds until the zero phase angle occurs, before
triggering the acquisition. This mode allows exa ct 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 t he length of
the acquisition buffer; see Section
6.3.3 for details. A positive
trigger delay positions the data window after the trigger event.
Positive trigger delays can exceed the length of the acquisiti on
buffer in which case the trigger event itself will not be i n the
buffer anymore. 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.

4.6.4 TRANSIENTS Screen Top-Level Menu
The Asterion Series power source provides the c apability of generating custom waveforms through
programming the output in a sequence of steps in a lis t 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 GUI 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 (refer to the
Asterion Series Programming Manual P/N M330100-01 distributed on the CD, CIC496) or the Asterion
Virtual Panels GUI; refer to AMETEK PPD website, www.powerandtest.com
, to download latest version.
The TRANSIENTS Screen provides access to the transient list data. A t ransient list of up to 100 data
points is possible, represented by 100 transient st ep numbers from 0 through 99.
The top-level menu of the TRANSIENTS screen is shown in Figure 4-21. It can be reached in one of two
ways:
1. Tapping TRANSIENTS on Home Screen of the front panel touch-screen;
2. Scrolling to TRANSIENTS with the encoder and depressing the encoder switch.
The UP arrow button will return back to the previously select ed screen menu (in this case the
Home Screen). The HOME button will return back to the home screen that has the top-level menu for the
sub-menu being displayed; that is HOME Screen f o r the TRANSIENTS screen top-level menu.

Asterion Series User Manual – 14U Models California Instruments
The SETTINGS menu has the following fields:
Entry Description
Phase Sets the output phase to which the programming of the transient s will
be applied.
Time Sets the units for time of the transient step; the default unit s 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 t i m e
duration scale selection affects both the Time and End Delay
parameters.
Volt(age) 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 percent age of
the steady-state setting.
Freq(uency) 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 A Shows the start phase angle of the voltage transient in degr ees.
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 brea ks;
Single: Each step is executed one at a time.
Trig(ger) The present state of the trigger settings is shown in the TRIG field.
Tap on the field to open the TRIGGER sub-menu to change settings;
refer to Figure 4-23.

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 a m pl i t ude at t he
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 rat e 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.
M330511-01, REV-B 99
Asterion Series User Manual – 14U Models California Instruments
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 t o
a higher value, while sag is a change to a lower value. After the
time duration has expired, the output voltage returns t o 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 specif ied rate
of change, while a FREQUENCY STEP is an instantaneous
change in output frequency. The new value will be hel d 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.
FREQUENCY SURGE/SAG FREQUENCY SURGE and SAG are temporary changes in
frequency. The output frequency will change from i ts 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 frequency retur ns
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.
