Keithley Series 2230G USB/GPIB DC Power Supplies

The Keithley Series 2230G is a multi-channel programmable DC power supply engineered for precision voltage and current control across diverse test environments. These instruments deliver isolated, low-noise outputs with linear regulation, remote sensing on all channels, and full USB/GPIB programmability. Built for labs, production test floors, and R&D facilities, the 2230G series supports series and parallel channel configurations to scale voltage to 60 V or current to 15 A.
