APPLICATIONS
The WRA_CS-3W & WRB-CS-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.

*Input voltage can’t exceed this value, or will cause the permanent damage.
Note: The load shouldn't be less than 10%, otherwise ripple will increase dramatically.
Operation under 10% load will not damage the converter; However, they may not meet all specification listed.
