HP / Agilent 6477C DC POWER SUPPLY 0-220V / 50A

The HP/Agilent 6477C is a 10 kW DC power supply delivering 0–220 V and 0–50 A with dual-mode CV/CC operation. SCR-regulated architecture provides stable output across medium to high-power test, research, and industrial applications. Front-panel meters (2% accuracy) display voltage and current in real time, while remote programming and sensing via rear barrier strip enable flexible system integration. Multi-unit configurations support auto-series, auto-parallel, and auto-tracking modes.
