HP / Agilent 6634A DC power supply, 0-100 Vdc, 0-1 A

The HP/Agilent 6634A is a 100 W single-output DC power supply engineered for systems and production test applications. It delivers 0–100 Vdc at 0–1 A with series-pass regulation, supporting both Constant Voltage (CV) and Constant Current (CC) modes. The unit sources and sinks current, enabling rapid output down-programming and improved test throughput. Built-in digital voltmeter and precision current shunt provide real-time output monitoring. HP-IB (IEEE 488) interface enables full remote programmability, status reporting, and user-defined fault condition monitoring.
