This unit
The Keithley 2231A-30-3 is a triple-channel programmable DC power supply delivering 195 W across three isolated output channels. Two channels provide 0–30 V DC at 0–3 A; the third delivers 0–5 V DC at 0–3 A. Independent control and remote sensing on all outputs enable precise, flexible power delivery for demanding test and measurement applications. The instrument combines high accuracy (0.06% voltage setting, 0.2% current setting), low noise (<5 mVp-p per output), and onboard setup memory for 30 configurations, making it essential for engineers designing and validating multi-rail circuits in laboratory and system integration environments.
