HP / Agilent 6633A DC power supply, 0-50 Vdc, 0-2 A

The HP/Agilent 6633A is a 100 W single-output DC power supply delivering 0-50 Vdc at 0-2 A with series-pass regulation. It operates in both constant voltage (CV) and constant current (CC) modes, with integrated digital voltmeter and precision current shunt for real-time output measurement. The unit sources and sinks current for rapid down-programming in production test environments. HP-IB (IEEE-488) interface enables full remote programmability, status reporting, and user-defined fault interrupts. Front-panel controls and fast-mode operation (400 µs rise/fall time, 2 ms settling) support time-critical test sequences.
