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.
