How to Connect LED Light Strips to Power Supply

After choosing the appropriate LED light strip power supply, you’ll connect the red and black wires of the LED light strip to the corresponding terminals or leads of the power supply. It’s essential to pay attention to the polarity of the light strip terminals, ensuring they match the positive and negative terminals of the power supply. (The symbol + or +V indicates the red wire; the mark – or -V or COM represents the black wire).

Can I Connect Multiple LED Light Strips to the Same LED Power Supply?

Yes, you can. However, ensure that the wattage of the LED power supply is sufficient and that the LED light strips are connected in parallel with the LED power supply to reduce voltage drop.

How Far Can I Install LED Strips from the LED Power Supply?

The farther the LED light strip is from the power supply, the more noticeable the voltage drop. If you’re using long cables from the power supply to the LED light strip, ensure these cables are made of thick copper and use large gauge cables as much as possible to minimize voltage loss.


Installation Tips for LED Power Supplies

LED drivers, like most electronic products, are susceptible to moisture and temperature. You need to install LED drivers in a dry location with adequate air circulation and ventilation to maintain their reliability. Proper installation is crucial for air circulation and heat transfer, ensuring optimal performance and longevity.

Leave Some Spare Power for Your LED Power Supply

Make sure not to consume the full capacity of the power supply. Leave some room to use only 80% of the maximum rated power of the driver. Doing so ensures it doesn’t run at full power constantly and avoids premature heating.

Avoid Overheating

Ensure the LED power supply is installed in a ventilated environment. This aids in air helping the power supply dissipate heat, ensuring it operates at the appropriate ambient temperature.

Minimize LED Power Supply “On” Time

Install a switch at the mains input of the LED power supply. When lighting isn’t needed, turn off the switch, ensuring the LED power supply is genuinely off.

Addressing Common LED Power Supply Issues

Always ensure correct wiring before powering up. Incorrect wiring can permanently damage the LED power supply and LED light strips.

Ensure the voltage is correct. You must ensure the input and output voltage of the LED power supply are correct. Otherwise, incorrect input voltage may damage the LED power supply, and incorrect output voltage may damage LED light strips.

Make sure the LED power supply wattage is sufficient. When the LED power supply wattage is insufficient, it may damage the LED power supply. Some LED power supplies with overload protection will shut off and turn on automatically. You may see the LED light strips constantly turning on and off (flickering).

When selecting an LED power supply for LED light strips, consider the required current, voltage, and wattage. You also need to consider the size, shape, IP rating, dimming, and connector type of the power supply. Once you’ve considered all these factors, you can choose the right LED power supply for your project.
