New Compact MEAN WELL LRS-1200 Power Supplies Expand the MEAN WELL Family of Power Sources.

The popular MEAN WELL SE-1000 series has been on the market for over 20 years and has become a true bestseller, widely used in industrial control systems, telecommunications equipment, LED lighting, security systems, and more. Among the power supply features that interest consumers in 2025 are compact size and energy efficiency. Therefore, the capabilities of SE-1000 are no longer sufficient for modern market needs. To meet these demands, MEAN WELL introduces the new LRS-1200 series: a compact enclosed power supply.

Why does MEAN WELL recommend the LRS-1200 series as a replacement for the SE-1000 series?
Both power supplies are enclosed AC/DC switching converters, supporting remote control, DC OK signal, and remote sense voltage drop compensation.
Common features of MEAN WELL SE-1000 and LRS-1200 AC/DC Power Supply Series
-
All key protections: short circuit, overvoltage, overheat, overload
-
Designed for installation in industrial systems with active fan cooling
Differences between MEAN WELL SE-1000 and LRS-1200 AC to DC Converters
-
LRS-1200 is a more modern solution with higher power output (1200 W), peak overload capability up to 150%, and higher efficiency (up to 94%). It features a more compact enclosure, higher reliability (MTBF), a wider operating temperature range, and a longer warranty.
-
SE-1000 is a more affordable series with a wider selection of output voltages but is less efficient, heavier, and offers lower durability ratings.
How to choose an enclosed power supply up to 1200 W for your needs?
-
MEAN WELL LRS-1200 is better suited for new developments where compactness, energy efficiency, and reliability are crucial.
-
MEAN WELL SE-1000 is a viable budget option for less demanding applications or as a replacement in existing systems.
