Add 12 (output voltage at transformer + 2.5, which equals 14.5V. For example, if you measured actual voltage at the fixture to be at 9.0V, subtract 9 from 11.5 and you get a 2.5V difference. If the voltage drops below 11.5 (due to wire resistance) then push it back up so it is around 11.5V – 12V. In this case the best technique is to measure the actual output voltage at the light fixture using a volt meter. The need for multi-tap transformers comes about when long feed lines are needed to bring current to fixtures that are located further from the transformer and when total load on the line is fairly high. Sebco Transformers 1023 Indoor/Outdoor 150W Magnetic Transformer 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). Many versions are even hidden in a rock shaped enclosure. They are normally mounted to a wall, but also come as in ground transformers. Low voltage transformers convert standard home line voltage (usually 120 volts) to a lower voltage (usually 12 or 24 volts) enabling the attached components to operate safely. Low Voltage Transformers – What Are They? In addition, low voltage lighting is a popular choice for exterior lighting due to its ability to reduce hefty electricity consumption costs. LED lights mostly operate on low voltage.Īn increasing number of home-owners prefer low voltage lighting for their outdoor landscapes due to its safety and ease of installation. In order to reduce the consumption of electricity, and due to other benefits, modern low voltage and LED lighting is being used to a greater degree.
