The WRA_CS-1W & WRB_CS-1W 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 input voltage is required to be more
than 2:1;
2) Where the isolation voltage between input and
output is required;
3) Where the regulation of the output voltage and
the output ripple noise are demanded.
