Features
DATELs UPB Model, 25-40 Watt, single-output DC/DC power converters bring
you efficient "on-board" power processing in a cost-effective smaller package with
a standard pinout. The 2" x 3" UPB "footprint" conforms with the industry-standard
pinout and pin geometries of most 3" x 3" devices (a 33% space savings) while
delivering as much as 60% more power (40W vs. 25W).
Applicable to a wide range of telecom, computer and other OEM applications,
UPB Model DC/DC’s operate from four input voltage ranges (10-36V for "Q12"
models, 18-36V for "D24" models, 18-72V for "Q48" models, and 36-72V for "D48"
models). Available output voltages are 5, 12 and 15 Volts.
For improved reliability and affordability, DATEL exploits contemporary, high-
speed, automatic-assembly techniques to construct the UPB’s traditional, field-
proven, SMT-on-pcb designs. Devices employ corrosion-resistant steel cases with
heavy zinc top plates (traditionally referred to as baseplates). Heat generating trans-
former cores and power semiconductors are mounted directly to the baseplates,
which also 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 undervoltage and overvoltage shutdown,
output overvoltage protection, output current limiting, and thermal shutdown. All
UPB models are UL1950, CSA 22.2 No. 950, and IEC950 approved. Most have
been EMI/EMC characterized. Contact DATEL for the latest available information.
