3-65W Cost Effective AD/DC Open-frame Converter LO Series

MORNSUN launched high power density cost effective AC/DC open-frame power supplies LO series, which provides powers of 3W, 5W, 15W, 30W, 45W and 65W, and has multiple output voltages as optional. What’s more, its output voltage is up to 48VDC. LO03/05 series adopt SIP package pin-out and are easy to use. LO15/30/45/65 series are open frame power supply in PCB mount and are easy to use and maintain.

Product advantages:

  1. Cost effective - Better lead time and price.
  2. High isolation voltage - Its isolation voltage is up to 3000VAC, which can significantly improve the product reliability and protect the system safety.
  3. High reliability and complete protections - This LO series has a MTBF over 300,000 h and provide protections of output short circuit (OSC), output over-current (OCP), output over-voltage current (OVP), 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 safety standards and white goods standards - LO15/30/45/65 series are designed to meet IEC/EN/UL62368 standards. Besides, LO15/30 series meet white goods requirements.


Widely used in instrumentation, street lamp control, industrial control, communication and civil applications.
