The Keithley 2230-30-6 is a three-channel programmable DC power supply delivering 375 W total power across independently controlled, galvanically isolated outputs. Two channels supply up to 30 V DC at 6 A each; the third provides 5 V DC at 3 A. Linear regulation ensures sub-1 mV rms ripple and noise, protecting sensitive circuits from supply-induced disturbances. Voltage and current resolution reach 1 mV and 1 mA respectively, with basic accuracy of 0.03% for voltage and 0.1% for current.
