E3630A 35W, 6V/2,5A, +20V/0,5A, -20V/0,5A, triple output DC power supply

The Keysight (formerly Agilent) E3630A 35-watt triple-output power supply provides three DC outputs: 0 to 6 V with a maximum current of 1 to 2.5A and 0 to 20 V and 0 to -20 V with a maximum current of 0.5A. 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.
