Front-end power supply meets Climate Savers efficiency rating

Murata Power Solutions Inc. announces a new ac/dc front-end power supply for hot-swapping redundant systems that meets Climate Savers' 80+ Gold efficiency rating. The 2,200 W (220 Vac), 1,100 W (110 Vac), power-factor corrected D1U4CS-W-2200-12-HA4C has a main output of 12 V and a standby output of 5 V.

Designed for delivering reliable, high-density bulk power to servers, workstations, storage systems, and other 12-V distributed power architecture applications, the D1U4CS-W-2200-12-HA4C is packaged in a 1U low profile enclosure with overall dimensions of 14 x 4 x 1.6 in. 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 19-in. 1U power shelf to provide up to 8.8 kW of power.

The D1U4CS-W-2200-12-HA4C has class-leading power density of 24.5 W/cu. in. and achieves efficiency levels of between 92% (at 50% load) and 88% (at 20% 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 I2C bus interface.

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