Agilent/Keysight 6632B DC Power Supply

The Agilent/Keysight 6632B is a 100 W single-output DC power supply engineered for automated test systems requiring precision, speed, and measurement capability. Delivering 0–20 V DC at 0–5 A, this instrument combines benchtop accessibility with system-level programmability to accelerate development cycles and improve test repeatability. High-speed output programming completes in under 4 ms, with response times as fast as 400 µs in fast mode. The 6632B excels at characterizing battery-powered devices, offering precision low-current measurement down to the microamp level and load regulation of 2 mV across the full 0–100% load range.
