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.

No parallel connection or plug and play.
Note:
1. The load shouldn't be less than 10%, otherwise ripple will increase dramatically.
2. Operation under 10% load will not damage the converter; However, they may not meet all specification listed.
3. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
4. In this datasheet, all the test methods of indications are based on corporate standards.
5. Only typical models listed, other models may be different, please contact our technical person for more details.
