The Kepco BOP125 2250-T1A is a bipolar operational power supply delivering four-quadrant source and sink capability for precision voltage and current control in dynamic test and simulation environments. Built on high-speed power operational amplifier architecture, it sustains DC output and replicates arbitrary AC waveforms across its rated ranges without polarity switching. The unit excels in applications demanding agile voltage response and smooth linear control through both positive and negative operating quadrants.
