MORNSUN 120W Open-frame Medical AC DC Converter LO120-20BxxMU.jpg

To satisfy the demand of medical applications for medium power segment power supply, MORNSUN launches the high-reliable and cost-effective LO120-20BxxMU series (84W output power without fan, 120W output power with fan). The LO120-20BxxMU series is the most cost-effective choice for applications that do not have high requirements for size and active PFC function.

The LO120-20BxxMU series has the advantages of small size (4"*2"*1.26"), leakage current lower than 100μA, high efficiency, low power consumption, etc. It meets the reinforced insulation 2xMOPP and medical certification EN60601-1, ES60601-1. And it also has the complete protections of output short-circuit, over-current, over-voltage, etc.


1) High reliability

① High I/O isolation test voltage up to 4000VAC

② Low leakage current<100μA 

③ Meets 2 x MOPP safety certification

④ High output voltage accuracy

⑤ Meet EN60601-1, ES60601-1 standards

⑥ Low Noise

2) Compact size: 101.60*50.80*29mm

3) Wide operating temperature, high efficiency, low power consumption, low interference

① Operating temperature range:-30℃ to +70℃

② Efficiency up to 91%

③ Stand-by power consumption<0.3W

④ EMI meets CISPR32/EN55032 CLASS B, CE margin >6dB, RE margin >5dB


With a high-reliable design for the medical industry, the LO120-20BxxMU series also can be used in industrial control, electric power, security, smart home, etc.
