DC Supply Puts Out 2.5 kW

The GR Series of power supply front ends generate output voltages of 12, 24, 28, and 48 Vdc at power levels from 1.25 to 2.5 kW.

Aimed at general-purpose applications, each unit has individual input and output connections and built-in power factor correction circuitry. A miniature 10-pin connector handles control and monitoring signals while output is via copper bus bar. The 2U-high chassis-mount case, 4.9 in. (124 mm) wide and 13.1 in. (333 mm) deep, mounts on the bottom or side using 6-32 screws. Supplies operate in parallel via an output O-ring diode and a single-wire current-sharing connection. Control and monitoring signals provide for power fail, remote output adjust, current monitor, inhibit, remote sense, power good, and a thermal alarm. Protection features include overvoltage, thermal, and short-circuit/overload protection.
