APPLICATIONS
The WRA_ZT-1W5&WRB_ZT-1W5 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 ≤4:1);
2) Where isolation is necessary between input and
output (isolation voltage ≤1500VDC);
3 here the regulation of the output voltage and the
output ripple noise are demanded.
