Perfect for industrial applications in extreme conditions
The LFM550S series is specifically designed for demanding industrial applications, offering an outstanding combination of performance, efficiency, and reliability. The partially encapsulated and robustly constructed power supplies are ideal for continuous 24/7 operation in an extended industrial temperature range of -40 to +80°C. Typical application areas include automation, robotics, industrial PCs (IPC), vision systems, kiosk, telecommunications, network installations, energy infrastructure, remotely operated vehicles, marine, and offshore applications.

International certifications and safety standards
These compact switching power supplies have been tested and certified to the safety standard IEC/EN/UL62368-1 Ed.3 and conform to protection class I. The LFM550S series meets the highest electromagnetic compatibility (EMC) requirements and is certified according to EN55032 and CISPR/FCC Class B. Additionally, these power supplies are designed in accordance with the household appliance safety standard IEC/EN60335-1. To ensure maximum operational safety and protect connected systems, the AC/DC power supplies feature continuous short-circuit protection as well as over-temperature, overcurrent, and overvoltage protection. The LFM550S series is rated for overvoltage categories (OVC) III (up to 2000m) and II (up to 5000m).

High-efficiency performance in an ultra-slim 1-Inch power supply design
With 550 W of power and an ultra-slim 1-inch form factor, the LFM550S series delivers a powerful power supply solution with precisely regulated DC output voltage in a compact footprint. The partially encapsulated power supplies have compact dimensions of just 129.4 x 83.5 x 25.4 mm, making them ideal for applications with limited space and enclosed systems. The thermally optimised design with baseplate contact cooling enables fanless operation, which not only reduces noise levels but also extends the power supply’s lifespan, as no moving fan components can wear out. Efficient heat dissipation ensures consistently high performance and reliability over many years, even under extreme conditions.
