EA Elektro-Automatik EA-PS 10750-20 3U DC Power Supply

Overview

The EA Elektro-Automatik EA-PS 10750-20 3U is a high-performance programmable DC power supply from the PS 10000 series, designed for demanding laboratory and production testing applications. This 3U rackmount unit converts three-phase AC input into regulated DC voltage with efficiency exceeding 96%, delivering 0–750V at 0–20A with a maximum output of 5 kW.

The supply features a 5-inch TFT color touchscreen for intuitive control and monitoring, supporting constant voltage (CV), constant current (CC), and constant power (CP) regulation modes with fast crossover. Its robust design and flexible autoranging capability make it ideal for relay testing, onboard charger validation, and high-power laboratory applications, with support for parallel operation of up to 64 units via Master-Slave bus for systems exceeding 1920 kW.
