APPLICATIONS
The WRA_(M)P-3W & WRB_(M)P-3W Series
are specially designed for applications where a
wide range input voltage power supplies are
12
9-18
22
isolated from the input power supply in
a
9
333
33
distributed power supply system on a circuit
board.

2) Where isolation is necessary between input
and output (isolation ≤1500VDC);
3) Where the regulation of the output voltage and
the output ripple noise are demanded.
