The TDK-Lambda ESS Series 10 kW models are high-performance, high-density constant voltage/constant current (CV/CC) programmable DC power supplies. Housed in a compact 5U rack-mount chassis, these systems deliver reliable power ranging from 7.5V to 600V DC and currents up to 1000A. Standard analog programming and monitoring, multiple protection diagnostics, and optional digital interfaces make the ESS Series ideal for demanding industrial and laboratory applications.
