Described as an economical triple-channel power supply added to the company’s Series 2200 line of programmable dc power supplies, the Model 2231A-30-3 195W touts a high output accuracy and can handle a wide range of sourcing requirements for characterizing components, circuits, modules, and complete devices. Two of the output channels are typically used for powering analog circuits, with each capable of outputting up to 30V at 3A. The third channel powers digital circuits with up to 5V at 3A. Voltage read-back accuracy is 0.06% for each output channel and ripple/noise is less than 5 mVp‑p. Pricing for the Model 2231A-30-3 is $650 each.
