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);
