Agilent / HP / Keysight 6237B

The Agilent 6237B is a Triple Output Power Supplies.

The 6237B is a compact constant voltage/current limiting triple output power supply. Controls, meters and binding posts are logically arranged on a neatly laid out front panel. One voltage control simultaneously adjusts the 20V and -20V outputs, that track within 1% to power operational amplifiers and circuits that require balanced voltages. All outputs are protected against overload and short circuit damage by fixed current limiting circuits. For any overload conditions, the +20V and -20V outputs are limited to 0.5A and the +18V output is limited to 1.1A.
