D1U4CS-W-2200-12-HA4C power supply

Murata Power Solutions has unveiled a new AC/DC front-end power supply for hot-swapping redundant systems that meets Climate Savers' 80+ Gold efficiency rating. The 2200W (220Vac), 1100W (110Vac), power-factor corrected D1U4CS-W-2200-12-HA4C has a main output of 12V and a standby output of 5V.

Designed for delivering reliable, high density bulk power to servers, workstations, storage systems and other 12V distributed power architecture applications, the D1U4CS-W-2200-12-HA4C is packaged in a 1U low profile enclosure with overall dimensions of 355.6mm x 101.6mm x 41.0mm. The new unit has built-in variable speed cooling fans and is N+1 redundancy capable including hot-docking. If required, four units can be packaged into an optional 19in. 1U power shelf to provide up to 8.8kW of power.

The D1U4CS-W-2200-12-HA4C has class-leading power density of 24.5W/cu. in. and achieves efficiency levels of between 92 percent (at 50 percent load) and 88 percent (at 20 percent load). The unit features active current sharing on its main output and incorporates safety features that include over-voltage, over-current and over temperature (with auto-recover) protection. Status information is provided via front-panel LEDs, logic signals and an I?C bus interface.

The RoHS-compliant D1U4CS-W-2200-12-HA4C has an operating temperature range of -0C to +50C, mean time before failure of 400,000 hours and is compliant with CSA 60950-1-03/UL 60950-1 safety approvals.
