DESCRIPTION
The WRE_YD-6W&WRF_YD-6W 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.
