750W Fanless Slim-type AC/DC Enclosed Power Supply – LMF750-23BxxUH

Feb 14, 2023 | Literature

MORNSUN launched the new 750W fanless semi-potted slim-type AC/DC enclosed switching power supplies – LMF750-23BxxUH series. The series has the advantages of an 85-305VAC wide input voltage range, AC and DC dual-use, high-cost performance, high PF value, high efficiency, high reliability, 150% peak power, 5000m high altitude, etc.

LMF750-23BxxUH is a safe and reliable power supply with good EMC performance and safety specifications that meet the standards of UL/EN/IEC62368, EN61558, EN60335, and GB4943. These power modules are suitable for industrial and outdoor occasions where the application environment is relatively harsh, such as industrial control, lighting, security, electric power, communication, and smart home, etc.

Advantages

1. Ultra-slim shape, High power density

237mm*100mm*41mm, power density up to 12W/inch3

2. Wide range of applications

a. Comply with UL/EN/IEC62368, EN61558, EN60335, GB4943 standards

b. Wide input voltage range: 85-305VAC, 150% peak load output for 1-second

c. Operating temperature range: -40℃ to +85℃

d. Support side installation

e. PF>0.95 (Full load at 230VAC)

3. High reliability

Within 70℃, altitude below 2000m and natural air cooling environment, 3-year warranty;

Within 50℃, altitude below 5000m and natural air cooling environment, 5-year warranty.

b. Output short circuit, over-current, over-voltage, over-temperature protections

c. Leakage current < 0.75mA/277VAC.

d. Work without fan at full load

e. Adopting the semi-potted design to improve the reliability of the power supply in high-humidity, dusty, and other harsh environments, is better than the one with conformal coating on each side.

f. Meet Pollution Degree 3 (62368)

4. Green power

a. Efficiency of LMF750-23B24/36UH is up to 95%

b. Efficiency of LMF750-23B12UH is up to 94%

c. Efficiency of LMF750-23B48UH is up to 96%

5. Outstanding EMC performance

a. CE & RE meet CISPR32/EN55032 CLASS B

b. Harmonic current meets IEC/EN61000-3-2 CLASS A

c. ESD meets IEC/EN61000-4-2 Contact±8KV/Air±15KV

Applications

LMF750-23BxxUH can be widely used in the field of industrial, lighting, electricity, security, telecommunication, smart home, etc.
