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.
