DESCRIPTION
The WRA_YMT-2W & WRB_YMT-2W 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
≤1500VDC);
3) Where the regulation of the output voltage and the
output ripple noise are demanded.
