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 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.

The WR-ZS-3W series is a new family of isolated 3W DC/DC converters with
regulated 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 efficiency allows
–40° to +85°C operation temperatures.

Further features include remote On/Off control and continuous short circuit
protection. The very compact dimensions of these converters make them an
ideal solution for many space critical applications in battery-powered
equipment and instrumentation.
