Keithley models 2220 and 2230 multi-channel programmable DC Power Supplies combine 2 and 3 channels of output power to cost-effectively characterize and test a wide range of devices, circuit boards, modules, and products that require more than one power source. The model 2220 supply provides 2 channels, with each channel capable of outputting up to 30V and up to 1.5A. The model 2230 includes two 30V/1.5A channels and adds a 6V channel with up to 5A output for powering digital circuits. The models 2220 and 2230 multi-channel Power Supplies offer an excellent combination of performance, versatility, and ease of use to maximise the information from characterization or test as quickly and as easily as possible. They perform as effectively in automated test systems as they do in bench applications. Features Dual output model with two channels up to 30V/1.5A/45W each All channels are independently controlled and have isolated outputs for maximum flexibility Remote sensing with all channels to ensure programmed voltage accurately being applied to the load Two 30V channels can be combined in series or in paralell to double output voltage or current 0.03% basic voltage output accuracy and 0.1% basic current accuracy ensure quality test data Low noise, linear regulation with <3mVp-p ripple and noise Voltage and current outputs for all channels are displayed simultaneously for easy observation Keypad entry allows fast, precise entry of output values Standard USB and GPIB interfaces for flexible automated testing
