The WRA_YMD-3W&WRB_YMD-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.
