The MORNSUN newest high-reliability DIN rail power supply LIMF series is ideal for wind power, railway, precision manufacturing, and other high-end fields with strict reliability and better performance.

LIMF240/480-23Bxx complies with explosion-proof certification, can work at full load at 60℃, and features salt-spray proof, 5G anti-vibration, conformal coating protection, etc. These series can be applied in various working conditions to provide a more stable and safer power supply to customers with a 5-year warranty.

Advantages

1. High performance – ideal for a wider range of applications

① Efficiency up to 95.5%

② Can work at full load at 60℃, with ultra-wide operating temperature: -40℃ to +85℃

③ 120% output power reserves (PowerBoost): 120% load for a long time work at 40℃

④ Universal 85 – 277VAC or 120 – 390VDC Input voltage (AC or DC input at the same terminal)

⑤ Built-in large electrolytic capacitor of 450Vdc, for stable operation in complex grid environments

2. High reliability – designed for stable operation in the extreme environment

① Pass the 1000 times cycle working test at 85℃ high temperature and 85% humidity

② Pass the continuous 48-hour grade salt-spray proof test, stable operated in extremely harsh environments, such as chilly seas or barren desert

③ High EMC performance: Surge meets IEC/EN61000-4-5 (L to N ±3KV/L or N to PE ±6KV)

④ 5G anti-vibration: Sine vibration of 10 to 500Hz and 2G to 5G for up to 2 hours

⑤ 5-year warranty: 40℃ MTBF: 878K hours, providing a long lifespan

3. Structure upgraded

① One-piece screw terminal for a secure installation

② Hexagonal Hole Perforated design to expand the heat dissipation area

③ Plating shell: Anti-corrosion and anti-oxidation

④ Highlight LED showing the work status clearly

⑤ Metal buckles at the back to support forward/reverse mounting

⑥ Perforated to comb the messy wire with cable ties

⑦ Attached datasheet in QR code for easy access

4. Explosion-proof

① Design complies with explosion-proof certification: ATEX, IECEx

② Production control meets explosion-proof standards: ISO/IEC 80079-34:2018

③ With conformal coating protection on each side
