Note:
1.*Input voltage can't exceed this value, or will cause the permanent damage.
2. The load shouldn't be less than 10%, otherwise ripple will increase dramatically.

APPLICATIONS
The WRE_ZD-3W&WRF_ZD-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≤4:1);
2) Where isolation is necessary between
input and output (Isolation Voltage≤3000VDC);
3) Where the regulation of the output voltage
and the output ripple noise are demanded.
