MEAN WELL LRS Series Enclosed Switching Power Supply
Complete Portfolio: 35W to 1200W | 1U Low Profile | High Reliability
General Product Features
- Ultra-Low Profile Design: The entire series features a space-saving 1U low profile design. Heights range from just 30mm (up to 350W) to 41mm (600W~1200W), making them ideal for compact cabinets.
- Input Flexibility: Universal AC input / Full range capabilities for lower wattages (35W~100W) and the LRS-150F. Switch-selectable AC input for mid-to-high wattages (150W~600W). The LRS-1200 accepts a wide 180~305VAC input.
- High Reliability & Durability: All models withstand a 300VAC surge input for 5 seconds, endure a 5G vibration test, and undergo a 100% full load burn-in test. Suitable for operating altitudes up to 5000 meters.
- Excellent Energy Efficiency: Extremely low no-load power consumption (ranging from <0.2W to <0.75W for most models) ensures compliance with worldwide energy requirements. Maximum efficiency reaches up to 94%.
- Comprehensive Protections: Built-in protection against short circuit, overload, and over voltage. Over temperature protection is included on 150W models and above.
- Cooling Mechanisms: Free air convection cooling for models up to 200W ensures silent operation. Models 350W and above utilize forced air cooling via a built-in DC fan with ON-OFF control.
- Warranty: The entire LRS family is backed by a reliable 3-year warranty.

Specialized & Premium Models
N2 Series (200% Peak Power Capability)
The LRS-100N2, LRS-200N2, LRS-350N2, and LRS-600N2 series are specially designed to deliver up to 200% short-duration peak power. This makes them the perfect solution for motor applications and heavy electromechanical loads requiring significantly higher power during startup, without needing to over-size the power supply.
LRS-1200 (1200W High Power)
The LRS-1200 is the flagship model providing up to 1200W output in a compact 41mm profile. It features premium industrial capabilities including:
- 150% peak power capacity for 5 seconds.
- Conformal coating for harsh environments.
- Built-in constant current limiting circuit.
- Remote Control (ON/OFF), Remote Sense, and DC OK signal.
LRS-150F (Full Range Input)
Unlike the standard LRS-150 which relies on a physical switch to change input voltage, the LRS-150F features an auto-adjusting Universal AC input (85~264VAC Full Range), eliminating the risk of switch-setting errors during global deployment.
Recommended Applications
- Industrial Automation Machinery: Reliable power for factory floors, robotic arms, and automated assembly lines.
- Industrial Control Systems: Stable DC voltage for PLCs, HMIs, and control cabinets.
- Mechanical and Electrical Equipment: General purpose powering for 3D printers, laser engravers, and CNC routers.
- Electronic Instruments & Apparatus: Clean power delivery for testing and measurement equipment.
- Household Appliances: Specifically certified and applicable for LRS-35, LRS-50, LRS-75, LRS-100, LRS-150, and LRS-150F series.
- Inductive and Capacitive Loads: The N2 Series (100N2, 200N2, 350N2, 600N2) is highly recommended for motors, pumps, and loads with high inrush currents.
