The Bel Power division of Bel Fuse Inc. released the GHBW53V08 Series of isolated DC-DC converters today. Engineered to power IEEE (News - Alert) Standard 802.3af-compliant Power over VoIP  and LAN applications, the series joins Bel’s broad offering of isolated and non-isolated power DC-DC converters for high-speed telecommunications, networking and computing applications.
Bel's DC-DC converters are designed to power remote devices in such applications as VoIP and Power-over-LAN . The product has exceptional high-power density, and is a good choice for applications where space is limited and a large number of remote devices need to be powered. The Series has a basic isolation level from input to output of 2250VDC, putting it in compliance with the requirements of IEEE 802.3af. It has also been designed to minimize common-mode noise.
The parts are packaged in the industry standard 1/2 brick (2.28" x 2.4") form factor, and are able to deliver up to 424W of output power at higher voltages, or up to 8A of output current at an output of 53V. They also boast a low thermal impedance baseplate that allows the addition of a heatsink to increase the usable power for any ambient temperature and airflow condition.
The devices’ programmable microcontroller provides many protection and control features, such as remote on/off, input and output OVP, input under-voltage lockout, over-temperature protection, current limit and short circuit protection. Parts also offer remote sense and output trim over the range of 42 to 56V. The RoHS 5/6 converters have an operating temperature range of -40 to +100 degrees C, and switch at a fixed frequency .
