PRODUCT OVERVIEW
The high efficiency, low noise and long-term reli-
ability that defines DATEL DC/DC Converters now
comes to you in the standard “half-brick” configu-
ration (2.3˝ x 2.4˝ x 0.40˝). All models in our new
UCH Series meet UL/EN60950-1 safety require-
ments, including each European country’s devia-
tions. All models have BASIC insulation; guarantee
2250Vdc (in to out) isolation; and because they are
designed with Class B thermal insulation, satisfy
all safety requirements over their full operating
temperatures. Double lead-free construction/attach
meets stringent RoHS specifications.
UCH Models are designed for demanding tele-
com, datacom and networking applications. Their
“semi-synchronous-rectifier” design achieves
impressive efficiencies. Output voltages are
1.8 to 15 Volts. The input voltage range is 36 to 75
or 18 to 36 Volts. All models meet the Low Voltage
Directive (LVD).
For high reliability and affordability, DATEL
utilizes high-speed automatic assembly to
construct the UCH’s proven SMT-on-pcb designs.
An optional baseplate offers full output power at
maximum temperature.
UCH’s feature input filters, input undervoltage
and overvoltage lockout, output current limiting,
short-circuit protection, and thermal shutdown.
Additionally, all devices have output trim capability
and an on/off control pin that can be ordered with
either polarity.
