ASX Series AC Power Supply

ASX Series


The ASX Series is a family of High Performance Switching AC Power Sources covering the power range from 1.5kVA to 12kVA. The product line offers both single and three phase models. Units are conservatively designed and output power ratings are based on the most severe combination of input line, output voltage, power factor, and temperature.
Great emphasis has been placed on low acoustic noise, ease of installation, and maximum power per cubic inch of rack space. Control and operational features provide a high degree of application versatility and ease of use for the test engineer. Applications range from simple, manually controlled frequency conversion to harmonic testing and sophisticated bus programmable transient simulation.
Power conversion within the ASX Series is achieved by high frequency pulse width modulation, resulting in cool, quiet and efficient operation.

Special ASX Series Operating Features
Continuous Self Calibration

Provides for exceptional accuracy of the AC output Voltage. When enabled, accuracy improves to ±0.1% referenced to the power source internal voltmeter.

Programmable Dynamic Output Impedance – Prog-Z (optional on UPC1/3)

Programmable Output Impedance provides the operator with the ability to dynamically control the output impedance of the AC Power Source. Using the output current term as conditioned feedback signal to the output voltage circuits, positive or negative impedance may be programmed. This control simulates the effects of, or compensates for high peak current, distribution, or transformer losses of up to ±10% of the output voltage.
This feature creates positive, negative, or zero output impedance (Zo).
Compensates for line distribution or transformer losses.
Simulates a soft power line for product testing. Compensation range is ±10% of the output voltage.
Waveform Library

Up to 22 different waveforms can be stored in the waveform library for execution as part of a steady state program or for substitution in any output phase as part of a transient test program. Memory location #1 is a non-editable high resolution sine wave. Locations 2-22 are editable and can be substituted in any output phase. An unlimited number of waveforms may be stored on the computer for those using a programmable UPC.

Waveform Edit

A full-featured editor permits modification of a stored waveform in both time and frequency domains. This method can be used to quickly create spikes, dropouts, notches and other sub-cycle wave conditions. The resulting modified waveform is stored for execution in steady-state or transient programs.
Waveform Analysis (optional on UPC1/3)

Provides both graphic (using LabView for Windows®) and numeric displays of the harmonic structure of a voltage or current waveform. Each waveform is analyzed for its harmonic content up to the 51st harmonic. Amplitude and phase are reported to the local display. The LabVIEWT instrument driver displays numeric values as well as a graphic summary of the harmonic spectrum.

Waveform Synthesis (optional on UPC1/3)

Quickly create virtually any AC test waveform by building it out of harmonics. The process is as simple as keying in the magnitude and phase angle of each desired harmonic up through the 51st. Additionally, waveforms can be created by downloading from a host PC.

Time Based Transients

Create and execute transients that occur over a specified time segment to modify the output waveform, voltage, and frequency for any or all phases. An output trigger is provided for synchronizing external test equipment to the actual transient event.

Cycle Based Transients

Create and execute transients that substitute a waveform in any or all phases for 1 to 100 cycles. The waveform being substituted can be selected and/or modified from the waveform library.
