Tresco Lighting 12VDC Power Supply Options

Choosing a power supply is generally the starting point when working with Tresco LED Lighting products. Deciding which one will work best for a particular project can result in a smooth outcome. Tresco Lighting has multiple power supply options to work with and we’ll cover some of these to help assist with common questions.

Tresco offers various power supply options with 60W, 18W, 15W, 12W or 6W capacities. It’s important to make sure you add up the total wattage of your LED light fixtures so they don’t surpass that wattage limit. The video below does an excellent job explaining the universal capabilities and the overall benefits.

The power supplies are compatible with all of the Tresco 12V DC LED light fixtures. You can simultaneously use various puck lights, stick lights or FlexTape. Each light fixture will have its unique wattage. For example: we can use eight 3W puck lights and eight 4W/ft. Eurolinx fixtures on a 60W power supply as this equals 56 total watts. You may need to account for voltage drop within connection extenders or controllers, so leave some breathing room. It is also recommended that you do not extend a light fixture more than 15 feet away from a power supply and that extension/linking cords are only from Tresco to ensure compatibility.

Before we take a look at some Tresco Power Supplies, it’s important to know exactly where and how to use the products within a particular application. Tresco has provided a basic schematic overview using the Power Supply (A) in conjunction with a controller (C). Detachable Mounting Blocks (B) are provided with 18W and 60W Power Supply products.

You’ll notice the two options. Option 1 allows the user to have multiple light fixtures being operated by different controllers. Option 2 allows the user to have one controller operating all six light fixtures. Remember, the Power Supplies are dimmable on the trailing edge or the 12VDC side.

As the schematic shows, one thing to notice about the 60W and the 18W products is that the mounting block can be detached. On the other smaller wattage versions they are attached to the power supply. The ability to have a detachable mounting block gives you the option, like above, to have a controller or on/off switch in-between your power supply and mounting block. You can then connect six lights to the mounting block. If you need more lights, use another mounting block in the last space from the original block.

Question:

“What does the green light on the power supplies indicate?”

Answer:

If the light is on, it indicates it has power. If it strobes in and out, it means it has either been overloaded or it may be defective. The best way to tell is to completely unplug the lights from the power supply, wait a couple of minutes, then observe the green light again. If it has stopped strobing, then it was overloaded, if it continues to strobe, then it is defective.

Question:

“Why are my lights strobing in and out?”

Answer:

This can be caused by a couple things… 1) The power supply is overloaded and too many lights have been used. 2) The power supply overheated (does it have proper airflow and not encased?).
