PPS LSX Series Programmable AC Power Sources 1.5kVA to 6kVA

Maximize Performance, Versatility & Eliminate Downtime

The LSX Series is a family of highly capable, fully featured, single and three phase AC Power Sources using advanced PWM switch mode power conversion for maximum efficiency. Available models range from 1.5kVA to 6kVA, all equipped with multi-DSP controllers featuring a color touch screen user interface.

LSX Series power sources are cost effective and fully programmable for both basic frequency conversion and advanced AC power line disturbance test applications. For less demanding applications, a reduced feature set M version of the LSX is available as well.

Note: The LSX Series is not CE marked yet at this time.

The LSX Series is a family of High Performance Switching AC Power Sources covering the power range from 1.5kVA to 6kVA. 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 LSX Series is achieved by high frequency pulse width modulation, resulting in cool, quiet and efficient operation.

Special LSX 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 200 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. All other waveform Locations are editable and can be substituted in any output phase. An unlimited number of waveforms may be stored on an external computer as needed.

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 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.

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. The waveform being substituted can be selected and/or modified from the waveform library.

AC Test Power

The LSX Series Power Source is equipped multiple Digital Signal Processors (DSPs) to create a fully integrated test system. It supplies a variety of power conditions to the device under test and meters/analyzes all output performance parameters.  

 Frequency/Voltage Conversion

The LSX Series is an excellent source of stable AC voltage over the frequency range of 15 to 1200 Hz. The output frequency is quartz-crystal stabilized. Output voltages up to 600 VAC are provided.  

 Phase Conversion

With the ability to provide singe and three-phase outputs, the LSX Series is the perfect choice to provide 1 Phase to 3 Phase or 3 Phase to 1 Phase conversion.   The LSX controller provides both manual operation from the front panel or remote control via one of the standard control interfaces. A built-in LXI compliant web server allows control using a web browser from any PC, Tablet or Smartphone.
