APPLICATIONS

The WRA-YD-5W&WRB-YD-5W of 2:1.State of the art

SMD-technology guarantees a product with very high

reliability and good cost or performance ratio. High

efficiency allows an operating temperature range of -40℃

to +85 ℃ without derating. I/O-isolation of 1500 VDC

together with conducted noise compliance to EN 55022-A

and FCC, level A makes these converters ideal for a wide

range of applications in communications, mobile battery

powered equipments and industrial systems.
