Keithley 2200-32-3 – Power Supply, 32 Volts, 3 Amps

The Keithley 2200-32-3 is a single-channel programmable DC power supply delivering 0V to 32V at 0A to 3A with 96W maximum output. Built for benchtop and automated test system integration, it operates as both a constant voltage and constant current source. The unit features a vacuum fluorescent dual-line display showing programmed and actual values simultaneously, remote sensing for accurate load voltage compensation, and 40 setup memories for configuration recall. List mode capability enables creation of repeatable test sequences with up to 80 steps per list, supporting up to seven independent lists. Each list step defines voltage, current limits, and duration for continuous cycling. Protection circuitry safeguards the Device Under Test from damage. A floating voltage rating up to 100V (DC + peak AC) relative to earth ground accommodates diverse measurement configurations.
