Low profile 600-W power supply delivers 89 percent efficiency
Designed in a rugged 1U high chassis the eFO600 measures 98 x 173 x 38 mm and features a universal 85–264 VAC input with PFC and is RoHS compliant. The output provides for active load current share and has an on-board O-ring diode for N+1 parallel operation.
The primary output voltage features remote sense and may be specified as 12 V, 24 V, 28 V, 32 V, 48V or 56 V with an optional second output available at 3.3 V, 5 V, 12 V or 24 V, up to 5 A or 50 W maximum. A further option is a 5 V standby output.
The Gresham 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 over temperature 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 hours (300,000 hours on 12 V version) minimum, per BELCOR 332, issue 6 specification @ 30°C.
