Magna-Power Intros PQD Series Power Supplies

Magna-Power Electronics Inc. (Boonton, NJ) introduced its PQD Series of high-density, rack-mount, dc switching power supplies ranging from 3.3kW to 10kW. The series features 48 models with output voltages ranging from 5Vdc to 600Vdc and currents ranging from 5Adc to 900Adc.

The new power supplies use the power-processing engine of the PQ Series with multi-processor digital control for a combination of features, power, performance and ruggedness. The PQD Series have both stepless analog and digital control. The unit can be programmed from the front panel, through a rear connector, or through RS232 communications. An optional IEEE-488 to RS232 converter, Ethernet to RS232 converter, or other communications converter is available to change the communications protocol. Remote interface software is supplied to enable communications with the power supply. Calibration can be performed from the front panel.

The PQD Series features series and parallel master/slave operation; a high dielectric withstand of 2,500Vac; over-voltage and over-circuit protection shutdown standard; automatic V/I crossover; 100 memory states with front panel memory indicator; and auto sequencing by time or external triggering
