Keithley 2230-60-3 – 375W DC Power Supply

The Keithley 2230-60-3 is a 375 W, three-channel programmable DC power supply engineered for multi-voltage testing and complex circuit characterization. Three independent, isolated output channels enable simultaneous measurement and control of diverse load configurations. Linear regulation delivers sub-1 mV rms noise, critical for sensitive device testing. The 2U half-rack form factor supports benchtop or rack-mounted deployment without sacrificing output capability or measurement resolution.
