Agilent/Keysight 6684A/V50 DC Power Supply

The Agilent/Keysight 6684A/V50 is a single-output DC power supply delivering up to 5120 W of stable power for demanding test and measurement applications. It provides 0–40 V and 0–128 A output with exceptionally low ripple and noise, eliminating the need for linear supplies in noise-sensitive environments. The unit supports both front-panel and remote control via GPIB and analog interfaces, with programmable over-voltage and over-current protection. Three units can be auto-paralleled for increased capacity, and outputs support series connection. CSA-certified and UL-listed for Installation Category III environments.
