XP Glassman’s EV Series are sophisticated 3 kW high voltage AC/DC power supplies with low ripple and noise. They are air insulated, fast response, 2U rack-mount units with tight regulation. A range of models is available with output voltage ranges from 0 to 750 VDC through 0 to 1.5 kVDC.

The EV series features active power factor correction (PFC) over the single-phase input voltage range of 198 to 264 VAC. Either terminal of the floating output may be grounded for operation as a positive or negative supply. Up to four identical supplies may be operated in parallel with user-configurable master and active current sharing. EV Series 2U rack-mount supplies may be stacked with no space required between supplies.

Front panel digital encoders provide high-resolution local adjustment of voltage and current program. A remote analog interface enables user selectable 0 to 5 V or 0 to 10 V analog programming. Integral RS-232, RS-485, USB and optional Ethernet communications provide remote control program and monitor with 12 bit accuracy. A rear panel switch allows selection of either constant-current or current-trip operation. The unit stores power supply parameters at each AC turn-off sequence.

Ripple is less than 0.1% RMS of rated voltage at full load up to 1 MHz. Total ripple and noise is less than 0.4% peak-to-peak of rated voltage up to 20 MHz. The EV Series’ standard operation mode is constant voltage/current. Automatic crossover from constant-voltage to constant-current regulation provides protection against overloads, arcs and short circuits. Forced air cooling with high-speed frictionless bearing technology fans reduces noise and extends fan life.

Standard accessories for the EV Series include a line cord, null modem cable, RS485 daisy chain cable and USB cable.
