Agilent/Keysight 6267A DC Power Supply

The Agilent/Keysight 6267A is a 400 W DC power supply engineered for precision electronic testing and development. It delivers 0–40 Vdc at 0–10 A with exceptional load and line regulation: ≤0.01% + 200 µV for voltage and ≤0.02% + 500 µA for current. A transistor series-regulator/triac-preregulator circuit ensures high efficiency, excellent voltage stability (≤0.03% + 2 mV), and low ripple and noise.

The supply operates in both constant voltage and constant current modes, supporting auto-series, auto-parallel, and auto-tracking configurations. Dual analog meters display voltage and current in real time. Output voltage and current are continuously variable with no range switching required.

Remote sensing and operator-adjustable overvoltage protection with crowbar protection are included. External control via resistance or control voltage is available through rear-panel barrier strip connections. The 6267A occupies standard 19-inch rack width, weighs 44 lbs, and measures 8 × 19 × 21 inches.

Input requirement is 115 VAC.
