ASX Series

115ASX

Power: 1.5kVA

Voltage range: 0-132V

Current range: 0-16Arms, 35Apk

Single phase

Power conversion within the ASX Series is achieved by high frequency pulse width modulation, resulting in cool, quiet and efficient operation.

Key Features:

• 22 Waveform Library - Arbitrary Waveform Generator
• 15 to 1,200 Hz Operation - 5,000 Hz Bandwidth
• Precision True-RMS metering of volts, amps, and power for displays and reporting
• Compatible with UPC Studio graphical user interface
• RS-232 Interface with SCPI compatibility
• 99 stored programs for both static and dynamic Transient Testing
• LabVIEW for Windows®/LabWindows® drivers
• Waveform Creation by Harmonic Synthesis
• Harmonic Analysis (Voltage and Current)
• Metering of RMS and Peak Values
• Continuous Self Calibration
• Precision Voltage Programming - 0.05% with CSC engaged
• Programmable Output Impedance
• Externally Referenced Meter Calibration

All ASX Series power source models may be equipped with a digitally programmable Oscillator/Controller or a manual version.

All operating functions may be controlled from either the front panel or from a remote RS-232 or IEEE 488.2/ SCPI BUS. LabVIEW for Windows® and LabWindows® Instrument Drivers are available.

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

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 

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

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.
