Agilent/Keysight 6632A-020 DC Power Supply

The Agilent/Keysight 6632A-020 is a 100-watt single-output DC power supply engineered for systems-level test and design applications. It delivers 0–20 Vdc at 0–5 A with programmable constant voltage (CV) and constant current (CC) operation, supported by current sinking capability for rapid down-programming in production environments. Built-in digital voltmeter and precision current shunt enable direct measurement and readback of output parameters.
