Agilent/Keysight 6626A DC Power Supply

The Agilent/Keysight 6626A is a four-output linear DC power supply engineered for precision test environments requiring stable, low-noise power delivery. Each output operates independently with dual-range capability, offering two 25 W outputs and two 50 W outputs to accommodate diverse voltage and current requirements. GPIB programmability enables automated control and monitoring, while 14-bit resolution ensures repeatable voltage and current settings across test sequences.
