The WRA_YD-3W&WRB_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
*Input voltage can’t exceed this value,or will cause the permanent damage.
