The WRA_SP-2W & WRB_SP-2W 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:

Note:
15
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.
1.Models listed with strike-through text have been officially discontinued.
2.*Input voltage can’t exceed this value, or will cause the permanent damage.
