12V-Input DC-DC Delivers 240W of PoE-Compliant Power

Murata has announced the SPC-54/4.4-L12PG-C, which is designed to deliver isolated 54V Power over Ethernet (PoE) at up to 240W. This very compact SIP (single inline package) module can power up to nine PoE devices at 25.5W from a 12V source.

The SPC-54/4.4-L12PG-C was developed to deliver power to Ethernet devices over traditional Cat 5 network cables in accordance with IEEE 802.3 PoE requirements. This unique PoE source module is designed to operate in applications that support a 12V power source, converting 12Vdc to 54Vdc at 240W, to power and support multiple PoE devices.
