APPLICATIONS
The WRA_ZS-3W&WRB_ZS-3W 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 rangeâ¤4:1);
2) Where isolation is necessary
between input and output
(Isolation voltageâ¤1500VDC);
3) Where the regulation of the
Output voltage and the output
ripple noise are demanded.

with external capacitor
The WR-ZS-3W series is a new family of isolated 3W DC/DC converters with regu-
lated output, featuring ultra-wide 4:1 input voltage range. The product comes in a
ultra-compact SIP plastic package with a small footprint occupying only 2.0 cm2
(0.3 square in.) of board space. An excellent effciency allows â40° to +85°C operation
temperatures.
Further features include remote On/Off control and continuous short circuit protec-
tion. The very compact dimensions of these converters make them an ideal solution
for many space critical applications in battery-powered equipment and instrumen-
tation.
