150W 24V Mean Well LRS Power Supply Indoor

The Mean Well LRS-150-24 is a 24V, 150-watt indoor AC-DC power supply engineered for LED strip lighting, control systems, and other low-voltage devices. This compact switching supply delivers up to 6.25 amps of stable 24V output for reliable, long-run installations in residential and commercial projects.

Designed around a slim, vented metal housing, the LRS-series form factor fits neatly into tight spaces such as cabinets, enclosures, and equipment racks while maintaining excellent heat dissipation. A wide 85–132V AC input range at 47–63 Hz supports typical North American line voltages, making it suitable for most indoor electrical environments.

• Stable 24V, 150W output: Supports longer LED strip runs and multiple 24V loads (up to 6.25A).
• High-efficiency design: Up to 87% efficiency for reduced heat and dependable long-term operation
• Built-in protections: Short circuit, overload, overvoltage, and overtemperature safeguards for connected equipment.
• Compact indoor form factor: IP20-rated, low-profile (approx. 6.3 × 3.8 × 1.2 in) chassis for easy mounting.

This 24V 150W LED power supply pairs well with single-color and RGB/RGBW strip lights, LED controllers, and other 24V DC devices such as CCTV cameras and small amplifiers, provided total load does not exceed 150 watts.

Unlike generic plug-in adapters, the LRS-150-24 offers screw-terminal connections, integrated EMI filtering, and UL-certified safety compliance, making it suitable for professional lighting and control installations that demand consistency and reliability.

The unit is non-dimmable on its own but can support dimming when used with compatible low-voltage controllers or dimmers between the power supply and the LED load. With its compact metal housing, indoor IP20 rating, and multi-protection design, this Mean Well LRS-series power supply provides a robust foundation for 24V lighting and low-voltage DC systems.

Ideal applications include under-cabinet lighting, display and accent lighting, control panels, and other indoor 24V LED strip or device installations where stable, efficient power delivery is critical. 

WHAT'S INCLUDED:

• 1 × Mean Well LRS-150-24 24V 150W Indoor Power Supply Unit

Q: What is the Mean Well LRS-150-24 power supply used for?
A: The LRS-150-24 is a 24V, 150W indoor AC-DC power supply for low-voltage systems. It is commonly used to power 24V LED strip lights, LED controllers, and other DC devices that require stable 24V output up to 6.25A.

Q: Who is this 24V 150W power supply designed for?
A: This power supply is designed for electricians, installers, integrators, and advanced DIY users building 24V lighting or control systems. It suits residential, commercial, retail, and display projects where a reliable, UL-certified indoor 24V source is required.

Q: Is the LRS-150-24 dimmable, and how can it be used with dimmers?
A: The LRS-150-24 itself is non-dimmable, so it does not respond directly to wall dimmers. For dimming, it is typically paired with a compatible 24V LED controller or dimmer placed between the power supply and the LED strips, allowing brightness and color control on the low-voltage side.

Q: What are the key electrical and physical specifications of this power supply?
A: The unit accepts 85–132V AC input at 47–63 Hz and provides 24V DC output up to 150W (6.25A). It features IP20 protection, a vented metal housing, and approximate dimensions of 6.3 × 3.8 × 1.2 inches (159 × 97 × 30 mm) for indoor installations.

Q: Can this power supply be used outdoors or in damp locations?
A: No, this model is rated IP20 and intended for indoor, dry-location use only. For installations in damp or outdoor environments, a power supply with higher ingress protection and an appropriate enclosure should be selected to protect against moisture and dust.

Q: What devices are compatible with this 24V 150W supply?
A: Any 24V DC device within the 150W power budget is compatible, including 24V LED strip lights, LED controllers, CCTV cameras, small amplifiers, and other low-voltage electronics. Total combined load across all devices should not exceed 150 watts or 6.25 amps at 24V.

Q: How should this power supply be installed and maintained?
A: The LRS-150-24 should be mounted in a well-ventilated indoor area, with wiring completed by a qualified person following local electrical codes. Periodic checks for secure connections, adequate airflow, and dust build-up around the vents help maintain long-term performance and thermal stability.
