LSX Series

The LSX Series AC Power Source is designed for low power, ranging from 1.5kVA/kW up to 6kVA/kW in single and three phase. This AC power source has an advanced PWM programmable controller and is a cost-effective option for frequency conversion, advanced power line disturbance tests, aerospace compliance, ATE, appliances, and UPS applications. For applications not requiring advanced features, a basic function set M version of the LSX is available.

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.

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. Not supported on LSXM models.

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. Locations 2-200 are editable and can be substituted in any output phase. Not supported on LSXM models.

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.
• Not supported on LSXM models.

Cycle Based Transients:

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

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.

Waveform Analysis:

Provides both graphic and numeric displays of the harmonic structure of a voltage or current waveform on the front panel color display or in any web browser using the LAN or USB interface. Each waveform is analyzed for its harmonic content up to the 51st harmonic. Amplitude and phase are reported to the local display. Displays numeric values as well as a graphic summary of the harmonic spectrum. Not supported on LSXM models.

Waveform Scope Capture and Synthesis:

A digital storage scope function captures voltage and current waveforms for up to three phases in real time. Display is available on the front panel LCD or with higher resolution on a web browser. To create harmonics waveforms for immunity testing, quickly create virtually any AC 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. Not supported on LSXM models.
