The 2220 and 2230 series multi-channel programmable DC power supplies are cost-effective, and ideal for testing various devices, circuit boards, modules and products that require multiple power inputs. The 2200 series power supplies feature two channels, each of which can output up to 30V voltage and up to 1.5A current. The 2230 series power supplies include two 30V/1.5A channels, plus an additional 6V channel that can output up to 5A current to power digital circuits. For Model 2231A-30-3, each of the two channels can deliver up to 30V at 3A current; the third channel can deliver up to 5V at 3A current.
