Agilent/Keysight 6235A DC Power Supply

The Agilent/Keysight 6235A is a triple-output DC power supply engineered for benchtop development and testing of linear and digital integrated circuits. It delivers constant-voltage, current-limited operation across three independent outputs with configurable tracking and series capabilities. The 6235A combines a 0V to +6V output (1A max) with two ±18V tracking outputs (0.2A each), or alternatively stacks the ±18V channels in series for 0V to 36V at 0.2A.
