The LMFxx-23Bxx series of enclosed power supply launched by MORNSUN, can be used not only in the normal operating conditions, but also in applications with higher requirements for input voltage, temperature, humidity, altitude, and electromagnetic interference for long time. The input voltage range is as wide as 85-305VAC, so it is reliable for long time when the voltage exceeds 264VAC due to power grid fluctuations or some operation conditions such as generators. And the power range covers 100, 150, 200, 320W. At the same time, it has the advantages of isolation voltage as high as 4000VAC and high PF (power factor) of 0.95. It accepts AC or DC input, and meets UL62368, EN62368, CB62368 and GB4943certification standards.

Main Challenging Condition:

Voltage Fluctuation

The input voltage range is 85-305VAC/100-430VDC, which solves the three major shortcomings of conventional 85-264VAC input products:

  • 1,The universal input voltage of 85-305VAC covers the standard voltage of 110/220/277VAC.)
  • 2, It solves the power failure caused by voltage fluctuations in grid power distribution or generator.
  • 3, It can also work normally under the transient high input voltage (the input voltage exceeds 264VAC when the device is turned on or turned off).

High Altitude

It meets the 5000m altitude application requirement, and the product has passed high/low temperature altitude test, long-term aging test, etc.


  • 1,EMI meets CLASS B reducing harm to the human body and interference to other equipment;
  • 2,Surge immunity is up to 4KV, strong anti-interference ability is suitable for harsh environment applications.

High/Low Temperature

Wide operating temperature range is -30ºC to +70ºC. The product can still work at full load and has a strong start-up ability while at low temperature of -30ºC ; when it is running at 70ºC, the temperature rise of product components is low and the service life is long.

In order to meet the diversified application requirement, MORNSUN has simultaneously launched extended models:

LMFxx-23Bxx-Q: It has three-proof paint process, and features excellent insulation, multiple resistance of moisture, leakage, vibration, dust, corrosion, aging, corona and other properties, which is suitable for harsh industrial environments.

LMFxx-23Bxx-C:  It has terminal cover that can prevent the human from touching the terminal by mistake.


It is widely used in industrial automation equipment, control systems, electromechanical equipment, instrumentation, smart building, household appliances and other terminal products.
