APPLICATIONS
The WRA_LT-2W & WRB_LT-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.
