The WRA_(M)P-3W & WRB_(M)P-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);
• 1. Where isolation is necessary between input and output (isolation ≤ 1500VDC);
• 1. Where the regulation of the output voltage and the output ripple noise are demanded.
