The Ametek/Elgar/Sorensen DCS40-75E is a 3 kW programmable DC power supply delivering 0–40 VDC at 0–75 ADC for demanding R&D, manufacturing, and automated test applications. Built in a compact 1U chassis, it combines precision voltage and current regulation with dual-mode operation, remote programming via Ethernet/RS-232/IEEE-488.2, and comprehensive protection. Ten-turn potentiometers enable high-resolution front-panel control, while simultaneous digital metering and selectable remote sensing accommodate varied test configurations.
