Ultra-compact Size Isolated Regulated 1-3W DC/DC Converter

MORNSUN launched a ultra-compact size DC/DC converter series WRB, which features 2:1 wide input range, operating temperature range of -40℃ ~+85℃, and 1500VDC isolation voltage. What’s more, the size is 40% smaller than general products. Packages are available in SMD and DIP. In addition, its continuous short circuit protection can ensure the safety performance of back-end circuits.


Applications:
Widely used in communication, instruments, industrial control applications.



Features:

● DIP/SMD package with compact size

● 2:1 input voltage range: 9-18VDC/18-36VDC

● Operating temperature range: -40℃ ~+85℃      

● I/O isolation test voltage: 1.5k VDC

● Industry standard pin-out

● Continuous short circuit protection

● Meets EN62368, UL62368 standards
