APPLICATIONS
The
WRA_ZD-1W5&WRB_ZD-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) Where the regulation of the output voltage and the
output ripple noise are demanded.
