The Pacific Power 320ASX-UPC3/G is a programmable AC power source delivering 2 kVA rated power for demanding test, simulation, and compliance applications. Operating from single-phase 240 VAC input (208 VAC available on request), it generates output up to 300 V with selectable single-phase or three-phase configuration. The unit combines high-frequency pulse width modulation for efficient operation with quartz-crystal stabilized frequency control and TRUE-RMS metering across voltage, current, and power parameters.
