HP / Agilent 6612C 40 Watt System Power Supply, 20V, 2A

The HP/Agilent 6612C is a 40 W single-output DC power supply engineered for automated test equipment and benchtop measurement systems. It delivers 0–20 V at 0–2 A with exceptional load and line regulation, programmable via GPIB and RS-232 interfaces. Fast transient response, remote sensing capability, and built-in measurement accuracy make it ideal for component characterization, device testing, and systems requiring precise power delivery in space-constrained installations.
