Murata Intros 2100 Watt DC/DC Supply
2100 Watt DC/DC supplies.
Mansfield, MA — Murata Power Solutions has introduced its D1U4CS front-end 2,100 Watt DC/DC power supply. This highly efficient unit, typically 93 percent efficient at half load power, is designed to deliver bulk power to 54VDC distributed power applications.
With a floating output, the design engineer can wire the power supply in a +54V configuration for data centre environment or -54V configuration for telco central office environment. A 5VDC, 0.75A standby output is also provided.
Typical applications include use in telephone exchanges in-line from the battery-bank, providing a highly reliable and regulated supply. Capable of operating over a wide input range, from -40 to -72VDC, this compact 1U unit measures 344.4 x 101.6 x 40.6mm (13.5 x 4 x 1.6-in.) and has an extremely high power density of 24.3 Watts per cubic inch. Two internal fans provide forced air cooling. The D1U4CS is N+1 redundant, hot-swappable and capable of droop current sharing. It has a comprehensive set of power control, logic signaling and operational status functions. The supply can automatically recover from over-current and over-temperature faults. These faults and all other signals are available though the I2C/PMBus interface together with status information by front-panel LEDs.
