HP/Agilent E3631A 80 W Triple Output Power Supply, 6V, 5A & +or- 25V, 1A, 80W

The Agilent E3631A 80-watt triple-output power supply provides three dc outputs: 0 to 6 V with a maximum current of 0 to 5A and 0 to 20 V and 0 to -20 V with a maximum current of 1.0A. An auto-tracking feature lets you use one voltage control to adjust the +20 V and -20 V outputs simultaneously. The outputs track each other to within 1 percent, making it easy to adjust the power supply circuits requiring balanced voltages.
