Medical, industry and household certified 120-350W AC/DC converter LOF series

Medicine and healthcare, industry, intelligent building design requires a reliable power supply, which creates a growing demand for compact, high-performance, reliable and cost-effective AC/DC converters.


In order to meet the demand, MORNSUN has launched the inverters of the LOF series on the market. These are compact, open-frame AC/DC converters that have medical, industrial and home certifications. Due to the compact dimensions (4″× 2″ × 1″), active PFC, high insulation voltage of 4000VAC and very low leakage current (<0.1mA), while meeting the level of 2 x MOPP, the LOF series offers high safety and reliability. These features make it the optimal solution for a variety of applications, especially in the medical and healthcare sectors.

The most popular models from the LOF series are LOF225 with dimensions of 4″x2″x1″(1.7Wcm3), LOF120 with dimensions of 3″x2″x1.2″ (1W/cm3) and LOF350 with dimensions of 5″x3″x1″(1, 4Wcm3).
Below you’ll find the exact Part Numbers of LOF series products:

  • LOF120-20B12 basic parameters: 12V / 9,5A / 114W
  • LOF120-20B24 basic parameters: 24V / 5A / 120W
  • LOF225-20B12 basic parameters: Air cooling / 12V / 11,67A / 140W
  • LOF225-20B12 basic parameters: Air cooling / 12V / 11,67A / 140W oraz 13CFM fan cooled / 12V / 18,75A / 225W
  • LOF225-20B24 basic parameters: Air cooling / 24V / 5,83A / 140W oraz 13CFM fan cooled / 24V / 9,4A / 225W

Exemplary applications

Classic applications with the use of the LOF series transducer are medical applications and for use in smart home systems. Below we present two diagrams of example applications. The first is a modern X-ray device, and the second is an intelligent smoke and fume detector.
