Three isolated outputs with series and parallel tracking modes for general bench work. Ovento Systems carries the Keithley 2231A-30-3 as used and refurbished stock within our power supplies & electronic loads range, sourced through equipment liquidations, service company fleet upgrades and OEM trade-ins across North America and Asia.

Outputs are loaded and checked for regulation, ripple and programming accuracy, and fan and thermal behaviour is confirmed under load. Units are sold in tested, working condition and typically ship the same or next business day from Plano, TX. Demand for this model comes mainly from power electronics developers, battery test labs and production burn-in facilities. Quantity and dealer pricing is standard rather than exceptional, so send the numbers you need.

What is included with the 2231A-30-3

The unit ships with its standard accessories where those are present, and with a written statement of condition. Where an accessory is absent we say so and quote it separately if you need it. If you are completing an existing kit, tell us the part numbers you are missing and we will check accessory stock against them.

Buying this class of instrument used? Buying a used oscilloscope: what actually matters covers what to check before you pay.
