Murata has announced the D2U5T-H3-7000-54 hot-swappable, ac-dc power supply with wide-range three-phase input from Murata Power Solutions. This internally cooled supply provides a 7kW, 54Vdc main output at up to 95.5% efficiency at 50% load. A user selectable standby offers an output of either 3.3- or 5-Vdc. The D2U5T Series offers true 3-wire, 3-phase operation from either a Delta or Wye source. With an input range of 320-525Vac, the D2U5T accommodates 480Vac installations in North America as well as 380Vac installations internationally. With input from voltage sources between 180-264Vac, the D2U5T Series will provide reliable 3.5kW. Active power factor correction gives this supply a 0.99 power factor and less than 10% harmonic current.

Packaged in an industry-standard 2U format and delivering a 23.1 Watts-per-cubic-inch power density, the D2U5T is designed for use in industrial and large data center applications where high efficiency, high power conversion is vital. For larger power requirements, as many as three units can be connected in parallel. This will provide up to 14,000 Watts in N+1 operation, and up to 21,000 Watts in non-redundant applications.
