APPLICATION
The WRF_MT-3W Series are specially designed for
applications where a wide range input voltage power supplies
are isolated from the input power supply in a distributed power
supply system on a circuit board. For these DC-DC converters,
You can reduce the design point of failure and save the
development of micro power supply‘s manpower, material and
time costs, also better ensure product quality stability, protect
safety and reliability of the end of products.
These products apply to where:
1) Input voltage range ≤2:1;
2) 3.0KVDC input and output isolation;
3) Regulated and low ripple noise is required.
