DESCRIPTION
The WRA(B)-ZLS-2W series is a new family of isolated
2W dc-dc converter modules with regulated output,
featuring ultra-wide 4:1 input voltage ranges of 9-36 VDC
or 18-75 VDC.The product comes in
SIP-9 plastic package.
a ultra-compact
OUTPUT SPECIFICATIONS
An excellent efficiency up to 84% allows –40°C～+85°C
operation temperatures at full load. Further features
include remote On/Off control and continuous short circuit
protection. Typical applications for these ultra-compact
converters are battery operated equipment and distributed
power architectures in communication, instrumentation
and industrial electronics, everywhere where space on the
PCB is critical.1) where the voltage of the input power
supply is wide range (voltage range ≤4:1);

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 data sheet, 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.
RoHS COMPLIANT INFORMATION
This series is compatible with RoHS soldering systems with a peak wave solder temperature
of 300°C for 10 seconds.
The pin termination finish on the SIP package type is Tin Plate, Hot Dipped over Matte Tin
with Nickel Preplate. The DIP types are Matte Tin over Nickel Preplate. Both types in this
series are backward compatible with Sn/Pb soldering systems.
