Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your application.
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
WARNING
WARNING
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 ac cess to hazardous voltages within the chassis.
However, depending on the user’s application configuration, HIGH VOLTAGES HAZARDOUS TO
HUMAN SAFETY may be normally generat ed on the output terminals. The customer/user must ensure
that the output power lines are labeled properly a s t o the safety hazards and that any inadvertent conta ct
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 equipm ent and accessories.

The equipment used contains ESD sensitive parts. When installing
equipment, follow ESD Safety Procedures. Electrostatic discharges might
cause damage to the equipment.

Asterion Series User Manual – 14U Models California Instruments
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.
