All BASIC insulation; models mod dels have BA ASIC insulatio on; guarantee 2250Vdc out) isolation; and because they are designed (in to ou Class B thermal insulation, satisfy all safety with Cla requirements over their full operating temperatures. Construction/attach meets stringent RoHS-6 specifications. UCH Models are designed for demanding telecom, datacom and networking applications. Their “semi-synchronous-rectifier” design achieves NOT RECOMMENDED FOR NEW DESIGNS FEATURES  Standard “half-brick” configuration  Certified to UL-60950-1, CSA-C22.2 No. 60950-1, IEC\EN 60950-1, 2nd edition (some models pending)  Fully isolated, 2250Vdc guaranteed 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 SMTon-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.  Output voltages: 1.8 – 15 Volts  VIN range: 36-75V or 18-36V  Full 50-150 Watt output power  Reliable SMT-on-pcb construction  Input under and output overvoltage shutdown  Output current limiting and short-circuit protection  On/off, VOUT trim and sense functions  Modifications and customs for OEMs  RoHS-6 construction/attach +SENSE (6) +VOUT (5) +VIN (4) CASE (2) SWITCH CONTROL –VOUT (9) –VIN (1) –SENSE (8) PMW CONTROLLER REMOTE* ON/OFF CONTROL (3) INPUT UNDERVOLTAGE, INPUT OVERVOLTAGE, AND OUTPUT OVERVOLTAGE COMPARATORS OPTO ISOLATION REFERENCE & ERROR MAP VOUT TRIM (7) Typical topology is shown. *Can be ordered with positive (standard) or negative (optional) polarity.
