Mean Well LRS-75-24 – Compact Industrial Power Supply
The Mean Well LRS-75-24 is a high-performance enclosed switching power supply that delivers a stable 24V DC output at 3.2A, totaling 76.8W of clean, regulated power. Part of Mean Well's popular LRS series, it is designed for industrial, commercial, and automation applications where reliable power conversion from AC mains to low-voltage DC is essential.
Ultra-Compact 30mm Low Profile Design
At just 30mm in height, the LRS-75-24 is one of the slimmest enclosed power supplies in its class. This ultra-low profile makes it an ideal choice for 1U rack-mounted systems, space-constrained control panels, and applications where every millimeter counts. Despite its compact size, it delivers full-rated power without requiring a fan — relying entirely on free air convection for silent, maintenance-free cooling.
High Efficiency & Low Standby Power
With efficiency ratings reaching 91.5%, the LRS-75-24 minimizes energy waste and heat generation. Its no-load power consumption is under 0.3W, making it compliant with the latest energy efficiency standards and ideal for systems that need to remain powered on continuously without unnecessary energy draw during idle periods.
Built for Harsh Environments
Engineered to withstand 300VAC surge input for 5 seconds and pass a rigorous 5G vibration test, the LRS-75-24 is built for reliability in demanding industrial conditions. The wide operating temperature range of −30°C to +70°C ensures consistent performance in hot UAE warehouses, temperature-controlled server rooms, and outdoor electrical enclosures alike.
What's Included
- 1× Mean Well LRS-75-24 Power Supply Unit
- Screw terminal connection block (pre-installed)
- Product datasheet and documentation
Typical Applications
The Mean Well LRS-75-24 is a versatile power supply used across a wide range of industries for powering 24V DC loads:
PLC & Automation Panels
LED Lighting Systems
Industrial Machinery
Server & IT Equipment
Telecom & Networking
Security & CCTV Systems
CNC & Motion Control
Building Automation
Built-In Protection Mechanisms
The LRS-75-24 comes equipped with comprehensive protection circuits to safeguard both the power supply and connected equipment:
Short Circuit Protection
Automatic recovery with constant current limiting ensures the power supply shuts down safely when a short circuit is detected on the output, then restores normal operation once the fault is cleared — no manual reset required.
Overload Protection
Operating at 105–150% of rated load, the overload protection activates hiccup mode to prevent damage. The supply automatically recovers once the load returns to normal operating range, preventing permanent damage to components.
Over-Voltage Protection
The output voltage is continuously monitored. If it exceeds safe thresholds (typically 27.6–32.4V for the 24V model), the power supply shuts down to protect sensitive downstream electronics, PLCs, sensors, and actuators.
Environmental Durability
- Surge Withstand: 300VAC input surge for 5 seconds — handles unstable mains power common in industrial zones.
- Vibration Resistance: Tested at 5G (10–500Hz) — suitable for machinery-mounted applications.
- Temperature Range: −30°C to +70°C — reliable from cold storage facilities to hot factory floors.
- Humidity: 20–90% RH non-condensing — performs in humid Gulf climate conditions.
