Datasheet

The Myrra 47000 series of encapsulated Switched Mode Power Supplies (SMPS) are available at JPR Electronics. The 47000 series provides an alternative solution to conventional power supplies and transformers used in many low power applications. With over 30 fully certified standard models available for delivery from stock the Myrra 47000 series provides both a cost effective and fast time to market power solution.

Available in 2.5W, 5W, 7.5W and 10W versions and having the same footprint as industry standard PCB mounting EI30, EI38 and EI48 transformer types allows end products to be updated without redesign of the original PCB.

Principle benefits to designers include single and dual output versions available over the range 3.3 to 24VDC, wide input voltage range 85-265 VAC and 85-370 VDC, the same footprint as industry standard PCB mounted EI transformers with some three times the output power. Greater efficiency, typically 70%, than conventional transformers and low standby power consumption.

Main features include UL and VDE certified, universal input voltage, low standby power consumption meeting requirements of Energy Star and EC code of conduct, Class II - reinforced insulation, input/output isolation test voltage 4000 Vac, input protection by integrated fusible resistor/fuse, output short circuit protection with automatic restart when fault condition is removed, thermal shutdown with automatic recovery if internal temperature exceeds allowable value.
