Seasonal & Holiday Displays An excellent power supply for Christmas lights and other elaborate holiday setups. Power multiple strings of 12V LED lights from a single, concealable unit, simplifying your wiring and creating a clean, professional-looking display.
Retail & Commercial Signage Perfect for backlighting signs, powering display case lighting, or under-shelf illumination in commercial settings. The compact size and silent operation make it ideal for customer-facing areas where space is tight and noise is a concern.

How to Wire & Install This Power Supply

  1. Ensure the AC power is completely disconnected before beginning installation.
  2. Verify your LED lights require DC 12V. Connecting to other voltages will cause damage.
  3. Calculate your total load. For best performance and longevity, do not exceed 80% of the power supply's capacity (80W).
  4. Connect the AC input wires to the corresponding terminals: Live (L), Neutral (N), and Ground ( stackrel{⏚}{=}).
  5. Connect your LED lights' DC input wires to the output terminals, ensuring correct polarity: Positive (+) to Positive and Negative (-) to Negative.
  6. Double-check all connections are secure, then restore AC power to test your lighting setup.
⚠ Precautions
  • This is not a dimmable power supply. Do not use with TRIAC or 0-10V wall dimmers.
  • This unit is rated IP20. It must be installed in a dry, indoor location, protected from moisture and dust.
  • Ensure adequate ventilation around the power supply to allow for proper heat dissipation.
  • Improper wiring or overloading can be a fire hazard. If you are unsure, consult a qualified electrician.
  • For a detailed guide, learn how to Choose LED Strip Light Power Supply correctly for your project.

Frequently Asked Questions

Q: Is this power supply dimmable?

A:No, the SW12V100W is a non-dimmable switching power supply. It is designed to provide a constant 12V output and should not be connected to a wall dimmer.

Q: Can I use this power supply outdoors?

A:This power supply is IP20 rated and intended for indoor use only. It must be protected from moisture and the elements. For outdoor applications, you would need a waterproof power supply.

Q: What is the benefit of the ultra-slim design?

A:Its slim profile (25mm height) makes it significantly easier to install in tight spaces like inside or on top of cabinets, within narrow sign boxes, or behind displays where a standard-sized power supply would not fit.

Q: What does having two output channels mean?

A:It provides two pairs of positive (+) and negative (-) terminals. This allows you to wire two separate LED runs directly to the power supply, simplifying wiring and helping to balance the electrical load.

Q: How many feet of LED strip lights can this power supply run?

A:This depends entirely on the power consumption of your specific LED strip (watts per foot or meter). To find out, you need to know how to calculate power for your total strip length and ensure it does not exceed 80W (80% of the 100W rating).

Q: Does this power supply make any noise?

A:No, it features a fanless design that relies on free air convection for cooling. It operates silently, making it perfect for quiet environments like homes, offices, and studios.

Q: What is the recommended maximum load I should connect?

A:To ensure optimal performance and a long lifespan, we recommend loading the power supply to no more than 80% of its rated capacity. For this 100W unit, the recommended maximum continuous load is 80W.
