1W/3W Ultra-light Compact Size Non-isolated AC/DC converter --LSxx-K3BxxSS Series

MORNSUN recently launched an ultra-light compact size non-isolated AC/DC converter series LSxx-K3BxxSS, which requires minimal peripheral components, features flexible use and can convert AC to DC directly. Its nominal output voltage 5V and 12V are available now.

Product advantages:

●  Miniature

This non-isolated series has a small size of 25.21*9.5*17.43mm, and it is lighter and higher cost effective without the traditional transformer.

●  Minimal peripheral components

Minimal peripheral components required, flexible use and easy to operate.

●  High reliability and complete protections

This series has a MTBF over 300,000 h and provide protections of output short circuit (OSC), output over-current (OCP), which not only significantly reduce the failure rate of the converter itself but also enhance the safety performance of back-end power modules and the load in abnormal working conditions.

●  Meets the latest safety standards

It is designed to meet IEC/EN/UL62368 safety standards (EN62368 pending).
