Bel Fuse Announces 1/4 Brick DC-DC Converters With 4-to-1 Input Voltage Range
Bel Fuse Inc. announced that the 0RQB-C0U series of open-frame isolated dc-dc converters has joined the company’s offering of RoHS-compliant isolated and non-isolated power dc-dc converters for high-speed networking, telecommunications, and computing applications.
Housed in the industry standard 1/4 brick (2.28" x 1.45") package, the series provides up to 100W of output power from a nominal 48V input. Notably featuring a 4-to-1 input voltage range to accommodate both a 24 and 48V standard input voltage in the same module, it is moreover engineered with built-in input and output filtering to further minimize part counts. The devices operate at efficiencies up to 91% over an ultra wide range of output voltages extending from 1.2 to 12V.
Bel’s newest UL/cUL 60950-1 approved series may be specified for employment 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. Additionally, 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 (285 kHz) and have an operating temperature range of -40 to +85°C.
Pricing for the 0RQB-C0U series of dc-dc converters starts at $47.50 each in quantities of 1,000. Samples and production quantities are available from stock with lead times of up to 12 weeks.
