Keithley 2231A-30-3 3-Channel Isolated Bench Power Supply, 195W, 3 Output, 0 → 30V, 3A

Keithley Model 2231A-30-3 triple channel DC power supply can output a total of 195W of power, providing the power levels needed to energise a wide range of circuits and devices for benchtop work. Two channels can supply up to 30V at 3A each

the third channel can provide up to 5V at 3A.
• 100nA to 6A with high accuracy.
• Three isolated, independent, and adjustable outputs in one instrument makes it perfect for Design and Test of high power components and circuits
• Output a total of 195W of power with two 30V@3A outputs and one 5V@3A output
• Set voltage outputs with 0.06% basic accuracy and current outputs with 0.2% basic accuracy
• Output DC power with less than 5mVp-p noise
• Display voltage and current measurements continuously from all three outputs
• Double output levels by connecting the two 30V channels in series or parallel
• Store frequently used configurations in any of 30 setup memory locations
• Turn off any output after a predetermined test time with each channel's output timer

Features and Benefits

• All channels are independently controlled and are isolated to power a wide range of test setups
• All channels have remote sensing so that the programmed voltage is accurately applied to the load
• Set and monitor output voltages with 0.03% basic accuracy and 1 mV resolution
• Monitor load current with 0.1% basic accuracy and 1 mA resolution
• Low noise, linear regulation with <1 mVrms ripple and noise
• Combine channels in series to output as high as 60 V and in parallel with two or three channels to create capacity as high as 15 A (2230-30-6)
• Voltage and current outputs of three channels are displayed simultaneously for immediate observation of each output state
• USB and RS-232 interfaces and rear panel connections for automated test convenience
• KickStart Software support
