Bel Power Intros DC-to-DC Modules
DC-DC power converter.
Westborough, MA — Newly added to Bel Power division of Bel Fuse Inc.'s offering of RoHS-compliant isolated and non-isolated power DC-DC converters is the 0RQB-C0U Series of open-frame isolated DC-DC converters. Designed for use in high-speed networking, telecommunications, and computing applications, the converters are housed in industry standard brick (2.28 x 1.45-in. package.

The low-cost converters provide up to 100W of output power from a nominal 48V input. Notably featuring a 4-to-1 input voltage range to accommodate both a 24V and 48V standard input voltage in the same module, the modules are engineered with built-in input and output filtering to further minimize part counts. The highly reliable devices operate at efficiencies up to 91 percent over an ultra wide range of output voltages extending from 1.2 to 12VDC.

These new UL/cUL 60950-1 approved products may be specified for use in a broad array of distributed power architecture applications where space is limited, and overall weight is a factor. Among the most common uses for these high power density parts are in wireless networks, optical and access networks, as well as in industrial networks and equipment. In addition, their open-frame construction makes them well-suited for convection-cooled environments. The isolated DC-DC converters offer a full complement of control and protection features that include differential remote on/off, positive/negative remote sense, input over-under-voltage lockout, and over-temperature protection. Parts also offer output voltage trim, current limit, and short circuit protection. These devices switch at a fixed frequency (285kHz) and have an operating temperature range of -40 to +85°C.
