1W/3W Ultralight Compact Size Non-isolated AC/DC converter --LSxx-K3BxxSS Series- 08/01/2019      view:
MORNSUN recently launched an ultralight 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:
  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.
2.Minimal peripheral components 
  Minimal peripheral components required, flexible use and easy to operate.
3.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.
4.Meets the latest safety standards
  It is designed to meet IEC/EN/UL62368 safety standards (EN62368 pending).

Design reference:


Widely used in IoT, smart home, instrumentation, industrial control, communication and civil applications.

  > Ultra-wide 85 - 305VAC and 70 - 430VDC input voltage Range
