Half-Brick Power Module is designed for PoE applications.

Press Release Summary:

Meeting multiport IEEE 802.3at application requirements, EMH-54/3-Q48N-C DC/DC power module provides 54 V SELV output, 2,250 Vdc isolation, and Basic insulation system. Module can deliver 30+ W of power at 54 V to each of 4 PoE+ Ethernet ports or up to 162 W to loads requiring 54 V. Accommodating 18-72 Vdc input range, product offers efficiencies up to 91.5% and can be mechanically configured to operate in applications that require forced air cooling or sealed box applications.

Original Press Release:

162 W 54 Vout Half-Brick Power Module Suits PoE Applications

Murata today announced the EMH-54/3-Q48N-C power module designed specifically for Power-over-Ethernet (PoE) applications. The Murata Power Solutions EMH Series DC-DC power module provides a 54 V SELV output, 2250 VDC isolation and a Basic insulation system meeting the requirements for multiport IEEE 802.3at (PoE+) applications. The EMH-54/3-Q48N-C can deliver 30+ watts of power at 54 V to each of four PoE+ Ethernet ports or can deliver up to 162 watts to loads requiring 54 V.

The EMH was specifically designed for use in applications requiring a wide operating voltage range such as battery-powered systems (24 V, 48 V or 60 V) and wireless base-station applications. The modules accommodate a Vin range of 18 to 72 VDC suitable for applications across all regions of the world.

The EMH-54/3-Q48N Series can be mechanically configured to operate in applications that require forced air cooling or "sealed box" applications, by offering an open frame module for forced air cooling or adding an optional baseplate for mounting a heat sink or for conduction cooling in a "sealed box" application.

This highly functional, multipurpose DC to DC converter delivers 54 V @ 3 A over a wide operating input voltage range of 18 - 72 V with efficiencies up to 91.5 %. The modules are UL approved for PoE applications requiring a DC-DC module that will deliver a 54 V SELV output with a basic insulation system that has an isolation voltage rating of 2250 VDC. The module conforms to the Industry Standard, DOSA half-brick package measuring 58.4 x 61 x 12.7 mm (2.3 x 2.4 x 0.5 inches). An optional baseplate can be supplied if the application requires a heat sink, or for use in conduction cooling (sealed box) applications. Added protection features include input under voltage lockout, output current limiting, short-circuit protection, and thermal shutdown.
