Gresham Power low-profile 600 W power supplies

Gresham Power Electronics has announced the availability of its eFO600 range of 600 W, low-profile, high power density power supplies.

Designed in a rugged 1U high chassis, the eFO600 measures 98 x 173 x 38 mm, features a universal 85-264 VAC input with PFC and is RoHS compliant. The output provides for active load current share and has an onboard O-ring diode for N+1 parallel operation.

The primary output voltage features remote sense and may be specified as 12, 24, 28, 32, 48 or 56 V with an optional second output available at 3.3, 5, 12 or 24 V, up to 5 A or 50 W maximum. A further option is a 5 V standby output.

The eFO600 meets full international regulatory and EMC approvals (with external line filter) and has a typical full load efficiency of 89% at 230 VAC. All models have overtemperature protection and system signals and commands including inhibit (on/off), output fail, input fail and an optional I²C bus output. Operating temperature range is -40 to +50°C with linear de-rating to 50% output power at 70°C and MTBF is calculated as 500,000 h (300,000 h on 12 V version) minimum, per BELCOR 332, issue 6 specification @ 30°C.
