Westborough, Mass. The Bel Power division of Bel Fuse Inc. has released the GHBW53V08 series of isolated DC/DC converters that comply with the IEEE 802.3af standard for Power-over-LAN and voice-over-IP (VoIP) applications.
Designed to power remote devices in PoE applications, the GHBW53V08 DC/DC converters can deliver up to 424 W of output power at higher voltages, or up to 8 A of output current at an output of 53 V. The parts are packaged in the industry standard 1/2-brick (2.28 x 2.4 inches) form factor. Devices operate at efficiencies up to 94% over an optimized input voltage range of 38 to 55 Vdc. They feature a low thermal impedance baseplate that permits the addition of a heat sink to increase the usable power for any ambient temperature and airflow condition.
The device's programmable microcontroller provides control and protection features that include remote on/off, input under-voltage lockout, input and output OVP, over-temperature protection, current limit and short circuit protection. Parts also offer remote sense and output trim over the range of 42 V to 56 V. The RoHS 5/6 converters switch at a fixed frequency and offer an operating temperature range of -40° to +100°C.
Pricing: Starts at $75.00 each in quantities of 1,000.
Availability: Samples and production quantities are available from stock with lead times of up to 12 weeks.
