The Keithley 2230G series power supplies deliver up to 375W of power in a compact, 2U high, 1/2 rack wide enclosure. The adjustable, independent and isolated channels can test two single-voltage devices or a multi-voltage device with a power supply - this leads to maximum flexibility. Each channel of the Keithley 2230G power supplies offers a voltage accuracy of 0.03% and a 1 mV resolution and measurement. This ensures that the programmed voltage is applied very precisely to the output terminals. The remote sense lines for each channel also compensate for voltage drops caused by resistance in the test lines and ensure that the programmed voltage is applied to the load. The USB, GPIB and RS-232 interfaces enable complete control of the 2230G power supplies from a PC. Combine 30 V channels in series to increase the voltage up to 60 V, or connect two or three channels in parallel to output up to 15 A with the 2230G-30-6. The variant 2230G-30-3 has 2 channels with 30 V / 1, 5 A, 1 channel with 5 V / 3 A and thus a maximum power of 120 W.
