Modifications and customs for OEM’s
DATEL’s BMP Models are fully potted, 25-40 Watt, dual-output DC/DC converters designed to meet UL1950 and EN60950-1 safety standards. The
combination the BMP’s higher efficiencies and thermally conductive potting compound enables these devices to achieve higher operating temperatures
without derating. The 2" x 3" BMP "footprint" conforms to the standard pinout
and pin geometries of most 3" x 3" devices (a 33% space savings) while
delivering 60% more power (40W vs. 25W).
Applicable to a wide range of telecom, computer and other OEM applications,
BMP Model DC/DC’s offer ±5V, ±12V and ±15V outputs. They operate from four
different input voltage ranges with total available output being a function of the
selected range. "Q12" models operate from 10-36V and deliver 25W. "Q48" models
operate from 18-75V and deliver 30W. For "D24" and "D48" models, the input
ranges and output powers are 18-36V at 35W and 36-75V at 40W, respectively.
These devices employ corrosion-resistant metal cases with plastic headers.
Heat-generating transformer cores and power semiconductors are mounted directly
to the cases, which have threaded inserts for optional add-on heat sinks or pcb
mounting. Temperature derating information is provided for operation with and without heat sinks and forced air flow.
All devices feature input pi filters, input overvoltage shutdown, output overvoltage protection, output current limiting, and thermal shutdown. UL, CSA, EN and IEC
compliance testing is currently in progress (75V-input devices will be CE marked) as
are full EMI/EMC characterizations. Contact DATEL for the latest available information.
