HP 6554A System DC Power Supply

The HP 6554A is a 500 W single-output DC power supply engineered for automated test equipment and laboratory applications requiring stable, programmable voltage and current. This series-pass regulated supply delivers 0–60 V at up to 9 A (at 40°C), with exceptional load regulation of 4 mV and line regulation of 1 mV. Front panel and analog programming (0 to −5 V) interfaces enable flexible control in benchtop and integrated test environments.
