APPLICATIONS
The WRA_YMT-3W&WRB_YMT-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.
These products apply to:
1) Where the voltage of the input power supply is wide
range(voltage range ≤2:1);
2) Where isolation is necessary between input and
output (isolation voltage ≤1500VDC);
3) Where the regulation of the output voltage and the
output ripple noise are demanded.
