How do I choose a low voltage transformer?

What do you look for in a low voltage transformer?

The easiest way to start filtering out the right transformer is to determine if the low voltage light fixture you need to power requires 12 or 24 volts. You should be able to find this information in the description/specifications of any product. Also, determine whether your power source outputs 120 or 277 volts.

Are all low voltage transformers the same?

There are two versions of low voltage transformers, single-tap transformers (where all outlet taps are of the same voltage, 12V or 24V) or multi-tap transformers (which include multi voltage outlet taps like 12v, 13v, 14v,15v, 16v etc).

How many watts do I need for low voltage transformer?

Determine Your Transformer’s Current Capacity

First, you have to determine how many watts your transformer can hold. With low-voltage lighting, we recommend only using 90% of the available watts. This will ensure you don’t run into any issues by overloading your transformer and tripping the system.

What kind of transformer do I need?

On the back of your appliance, you should be able to find a label describing its specifications including its Wattage (W) or the Amperage (A) of the appliance. Example: If your appliance consumes 80 Watts then you need a AC100 transformer (100 Watts capacity) or higher.

What happens if you overload a low voltage transformer?

The transformer can’t cause damage to the power outlet. The overload transformer’s voltage would drop. The domestic plug’s voltage would be low.

How big of a transformer do I need?

Multiply the total wattage by 1.25 to adjust for loss due to cable distance. For the example, 240 x 1.25 = 300. The final number determines how large a transformer you need for your system. Choose a transformer that supplies no less than the required wattage and no more than 33 percent more.

What is considered a low voltage transformer?

A low voltage transformer is at the heart of every landscape lighting system. It converts 120 volt current to a low voltage current (between 12-15 VAC). The efficiency of this conversion determines how well the transformer controls the voltage output and how much energy is consumed in the process.

How many watts can a transformer handle?

Electronic transformers are cooler, quieter, and more compact than magnetic transformers. But, electronic transformers can’t power more than 300 watts, while magnetic ones can power as much as 1,200 watts.
