Rohde and Schwarz HMC8042 Power Supply, 2-Channel

The Rohde & Schwarz HMC8042 is a 2-channel programmable DC power supply designed for laboratory and automated test environments requiring stable, low-noise power delivery with precise control. Each channel independently supplies up to 60 W, with total system output reaching 120 W. The instrument supports independent, series, parallel, and tracking output modes, enabling flexible voltage and current configurations from 0 V to 32 V per channel and 0 A to 5 A per channel. Exceptional output regulation, low ripple and noise specifications, and comprehensive protection mechanisms ensure reliable performance in demanding applications.
