DESCRIPTION
The WRA(B)-ZS-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 a ultra-compact SIP-9
plastic package.
An excellent effciency up to 84% allows –40°C to +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);
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.
