The HP-Agilent 6632A is a 100 W single-output DC power supply engineered for automated test systems and precision benchtop applications. It delivers 0–20 V and 0–±5 A with series-pass regulation and independent voltage or current control in both constant-voltage (CV) and constant-current (CC) modes. The unit integrates a digital voltmeter and precision current shunt for real-time output measurement and readback. HP-IB (GPIB) remote control enables full programmability, status reporting, and user-defined fault condition monitoring.
