    ER-PS-SW Programmable AC Power Source

    Introduction

    ER-PS-SW series Programmable AC Power Sources have the ability to simulate the AC voltage and frequency used in all countries. They are excellent instruments for R&D, design production testing/evaluation, and QA verification. In addition, the frequency range covers 500 Hz, making these products ideal for commercial and defense avionics applications.

    The ER-PS-SW series delivers maximum rated power for any adjustable output voltage up to 300Vac (L-N)/520Vac (L-L )for 3 phase units, and at any adjustable frequency between 40Hz to 500 Hz.

    It integrates IGBT made by Mitsubishi, Siemens, and Infineon, and combines microprocessor and ARM &DSP control design together for quick response and higher reliability and parallel operation.
