APPLICATIONS
The WRB_S-1W
& WRB_S-2W series are
12

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:
9
1) Where the voltage of the input power supply is
wide range (voltage range ≤ 2:1);
12
15
67
7
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.
