Dual Output
BMP Models
High-Efficiency, Smaller-Package
25-40 Watt, DC/DC Converters
Features
DATEL’s BMP Models are fully potted, 25-40 Watt, dual-output DC/DC converters
designed to meet UL1950 and EN60950 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.
