PRODUCT OVERVIEW
DATEL’s UMP Models are fully potted, 25-40 Watt DC/
DC converters designed to meet UL1950 and EN60950-
1 safety standards. The combination of the UMP's
higher efficiencies and thermally conductive potting
compound enables these devices to achieve higher
operating temperatures without derating. The 2" x 3"
UMP "footprint" conforms with the 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, UMP Model DC/DC’s
operate from four input voltage ranges (10-36V for
"Q12" models, 18-36V for "D24" models, 18-75V for
"Q48" models, and 36-75V for "D48" models). Avail-
able output voltages are 5, 12 and 15 Volts.
For reliability and affordability, DATEL exploits
contemporary, high-speed, automatic assembly to
construct the UMP’s traditional, field-proven, SMT-
on-pcb designs. 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 add-on heat sinks or pcb mounting. De-
vices are specified for –40 to +100°C operation and
derating information is provided for operation with/
without heat sinks and forced air flow.
All devices feature input pi filters, input undervolt-
age and overvoltage shutdown, output overvoltage
protection, output current limiting, and thermal
shutdown. UL, CSA, EN and IEC compliance testing is
available (75V-input devices will be CE marked) as are
full EMI/EMC characterizations.

UMP Model DC/DC Converters are classified, by output power, into 25,
30, 35 and 40 Watt devices. For the single-output devices listed above, the
maximum available output power is the product of the nominal output voltage
and the maximum allowable output current indicated within the part number
(see Part Number Structure). A UMP-5/6-Q48, for example, can source
6 Amps from its 5V output (over its entire 18-75V input voltage range) deliv-
ering an output power of 30 Watts. A UMP-5/8-D48 can deliver
40 Watts.

Floating Outputs
Since these are isolated DC/DC converters, their outputs are "floating." Us-
ers may ground either the Common (pin 8) for normal usage or the positive
side (+Output, pin 9) to effectively reverse the output polarity.
Filtering and Noise Reduction
All UMP 25-40 Watt DC/DC Converters achieve their rated ripple and noise
specifications without the use of external input/output capacitors. In critical
applications, input/output ripple and noise may be further reduced by install-
ing electrolytic capacitors across the input terminals and/or low-ESR tanta-
lum or electrolytic capacitors across the output terminals. The caps should
be located as close to the power converters as possible. Typical values are
listed in the tables below. In many applications, using values greater than
those listed will yield better results.

Input Fusing
Certain applications and/or safety agencies may require the installation of
fuses at the inputs of power conversion components. For DATEL UMP
