Under-Cabinet & Shelf Lighting Install bright, functional task lighting in kitchens, workshops, and offices. The slim profile fits neatly behind cabinet trim or inside shelving units, providing ample power for high-brightness LED strips.
Retail & Signage Backlighting Ideal for backlighting commercial signage, retail displays, and exhibition stands. The compact, fanless design ensures silent operation and easy integration into custom fixtures where space is at a premium.

How to Wire & Install This Power Supply

  1. Step 1: Verify that your LED lighting system requires DC 24V and that the total power consumption does not exceed 120W (80% of the 150W capacity).
  2. Step 2: Ensure all power is disconnected from the AC source before wiring.
  3. Step 3: Connect your AC line voltage wires to the input terminals. Connect the Live/Hot wire to 'L', the Neutral wire to 'N', and the Ground wire to the 'GND' or ground symbol (〨).
  4. Step 4: Connect the DC output to your LED lights. Wire the positive (+) wire from your LEDs to the '+V' terminal and the negative (-) wire to the '-V' terminal. Double-check polarity.
  5. Step 5: Once all connections are secure, restore AC power and test the lighting system.
⚠ Precautions
  • This is a non-dimmable power supply. To dim your lights, install a separate 24V PWM dimmer between the power supply and the LED strips.
  • For optimal performance and longevity, do not load the power supply to more than 80% of its rated capacity (120W max recommended load).
  • This unit is rated IP20 and is not waterproof. It must be installed in a dry, indoor location with adequate ventilation.
  • Always ensure correct polarity (+ and -) when connecting the DC output to prevent damage to your LEDs.

Frequently Asked Questions

Q: How many feet of 24V LED strip can this 150W power supply run?

A:This depends entirely on the power consumption of your specific LED strip, measured in watts per foot or meter. For example, if your strip uses 4.4 W/ft, you could power up to 27 feet (120W ÷ 4.4 W/ft). Always check your strip's specifications and stay within the 120W (80%) recommended load.

Q: Is this LED driver power supply dimmable?

A:No, this is a constant voltage, non-dimmable power supply. To control the brightness of your lights, you will need to add a 24V PWM dimmer on the low-voltage side, between the power supply and the LED strips.

Q: Can I use this power supply for outdoor Christmas lights?

A:No, this unit has an IP20 rating, which means it is not protected against moisture. It is designed for indoor use only or within a suitable waterproof enclosure.

Q: What is the advantage of an 'ultra-slim' power supply?

A:The primary advantage is its compact, low-profile design. This allows it to be easily hidden in tight spaces like aluminum channels, behind trim, inside cabinets, or within signage, resulting in a cleaner and more professional installation.

Q: Does this power supply make any noise?

A:No, this model is fanless and relies on passive cooling through its ventilated metal case. This ensures completely silent operation, making it ideal for residential and noise-sensitive commercial environments.

Q: How do I determine the right size power supply for my project?

A:To find the right power source, you need to know how to calculate power for LED strip lights. We recommend reading our detailed guide for a step-by-step explanation.
