Dc-input front-end power supply are 1000vrms isolated

MURATA POWER SOLUTIONS D1U54-D-1200 series of dc-input front-end power supply modules are 1000vrms isolated, providing a 12Vdc output at 1200 Watts, with a standby voltage at up to 20 Watts of power. With a power density of 28 watts per cubic inch, the slim 54.5mm (2.15″) width and 1U height format minimizes space inside to maximize user utility, and user rear panel area. Products accommodate an operating input voltage range of -40Vdc to -72Vdc. The hot swap enabled products provide integral MOSFET ORing in conjunction with active current sharing of the main output. http://www.murata-ps.com
