DESCRIPTION
The WRE_YD-3W&WRF_YD-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 ≤3000VDC);
3) Where the regulation of the output voltage
and the output ripple noise are demanded.
