(in to ou isolation; and because they are designed
Class
with Cla B thermal insulation, satisfy all safety
requirements over their full operating tempera-
tures. Construction/attach meets stringent RoHS-6
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, Murata
Power Solutions 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 logic type.
