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). Available 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. Devices
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 undervoltage and 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.

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.

In critical, space-sensitive applications, DATEL may be able to tailor the inter-
nal input/output filtering of these devices to meet your specific require-ments.
Contact our Applications Engineering Group for additional details.
Input Fusing
Certain applications and/or safety agencies may require the installation of
fuses at the inputs of power conversion components. For DATEL UMP
DC/DC Converters, you should use slow-blow type fuses with values no
greater than the following:

These converters require a minimum 10% output loading to maintain specified regulation.
Operation under no-load conditions will not damage these devices; however they may not
meet all listed specifications.
➁
Application-specific input/output filtering can recommended or perhaps added
internally upon request. Contact DATEL Applications Engineering for details.
➂
Applying voltage to the Control pin with no input power applied can damage the converter.
➃
Listed spec is for input-to-output. Input-to-case and output-to-case isolation is 1000Vdc min.
