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 high voltage relative to chassis ground.

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

WARNING 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.

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 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.

Asterion Series User Manual – 14U Models

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.

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. 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 Asterion Virtual Panels GUI 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 relationships. 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 GUI.

2.1.2iX2TM 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 the output voltage is 50% of full-scale. The current ratings are also a function of output frequency, as shown in Figure 2-1 above 500 Hz for the AST12K3 and AST18K3 units.
