Keithley expands Series 2200 power supply range

Both supplies are said to offer greater output accuracy at lower cost than competing products, with output levels that address a range of sourcing requirements for characterising components, circuits, modules, and complete devices. The 2230-30-1 has two output channels, typically used for powering analogue circuits, each capable of outputting up to 30V/1.5A/45W, plus a 6V/5A/30W output channel for powering digital circuits. The 2220-30-1 also provides two output channels capable of outputting up to 30V/1.5A/45W. These output levels, combined with 1mV and 1mA resolutions, are said to allow a wider range of output power to be generated and a wider range of load currents to be read with greater precision. Rear panel remote sense terminals on each channel of the Series 2200 supplies are designed to compensate for voltage drops in the power supply leads to ensure that the correct voltage is delivered to the load terminals of the DUT, enhancing overall system accuracy. The devices also feature 0.1% basic current setting and readback accuracy, with less than 3mVp p ripple and noise to ensure high quality load current measurements. Each output channel is completely isolated, which allows the new supplies to power two isolated circuits with different reference points, eliminating the need for a second supply.
