Description

Op-amp stages, sensor front ends and bias networks usually need two rails at once. The Keithley 2220-30-1 power supply puts two isolated outputs in one case. Lost in HCM lists it for rental and sale, and it arranges service on request.

Two isolated outputs, one bench slot

A crowded bench loses time to extra leads, plugs and stands. A dual-output unit trims all three. As a result, a small team can share one slot and still run two circuits.

Each channel reaches 30 V and 1.5 A, and the listing gives a total of 90 W. Because the outputs stay isolated, you can feed two separate circuits without a shared return. The Keithley manual also covers channel combining if you need a split rail. Read it before you wire anything. Also, remember that the Keithley 2220-30-1 power supply has two channels, so a third rail needs another unit.

Jobs for a dual-channel supply

Bias an analog front end on one channel while the second channel runs the digital side.
Power a sensor board and its signal conditioner from separate outputs, so noise tracing is easier.
Run education labs where two students share one unit, because the outputs do not touch each other.

USB control and ordering checks

The listing names USB only, so a laptop can set and log both channels. If your rack needs GPIB, ask about the 2220G-30-1 instead. Next, confirm the AC line option, the leads and the software on your PC. Then set polarity and grounding on your own circuit before the first power-up.
