Industrial 100W Power Supply
The SMUGDESK LRS-100N2 is a Mean Well enclosed switching power supply rated at 100W continuous output. It accepts a universal 85~264VAC input and survives 300VAC surge events for five seconds. Four fixed DC voltage models are available: 12V/8.5A, 24V/4.2A, 36V/2.8A, and 48V/2.1A, all housed in a 30mm slim metal case. Fanless natural convection cooling allows operation from -30 to +70.
Upgrade From Standard LRS Units
This series replaces the classic LRS range by adding 200% peak load capability for five seconds, eliminating nuisance trips caused by motor, solenoid or LED strip inrush currents. The jump is worth it when existing supplies shut down during startup transients rather than sustained overloads. Built-in short-circuit, overload, overvoltage and overheat protections maintain 24/7 reliability in automation cabinets and security systems. No-load draw stays below 0.5W for energy-conscious installations.
Capacity And Headroom
Continuous delivery reaches 100W at up to 90.5% efficiency across the 12V, 24V, 36V and 48V models. The 200% peak reserve handles brief startup surges without tripping, then settles to rated current. Headroom runs out when average load exceeds the continuous rating or when ambient temperature pushes past 70 without additional airflow. The ultra-thin 129×97×30mm profile fits tight 1U spaces where bulkier supplies cannot be mounted.

Questions about this item
What are the exact mounting dimensions and screw-hole pattern for the 129×97×30 mm metal housing?
The enclosed unit measures 129 mm long by 97 mm wide by 30 mm high. The low-profile 1U metal case is designed for standard DIN-rail or panel mounting inside control cabinets using the integrated mounting tabs.
How do I wire the AC input terminals for the 85–264 VAC universal range, and what is the most common mistake?
Connect live, neutral and ground to the clearly marked input terminals; the supply auto-ranges from 85 to 264 VAC. The frequent error is reversing live and neutral or omitting the ground connection, which defeats the built-in surge and EMC protection.
When should I expect to replace the power supply, given the fanless natural convection design and -30 to +70 °C operating range?
With no moving parts and full short-circuit, overload, over-voltage and over-temperature protection, the unit is rated for continuous 24/7 operation. Typical service life exceeds several years; monitor output voltage drift and thermal rise as early replacement indicators.
