APPLICATIONS
The WRB_ZP-3W &WRA_ZP-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:

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.
