What are Low Voltage Transformers?

Any normal low voltage power transformers are mainly produced to reduce 120 volt line voltage to the secondary or the output voltage of the 12 volts. One among the many uses of low voltage transformer is for landscaping.

When using low voltage transformers for landscaping, remember that the transformer do not have any way of recognizing the line voltage. If in case the simply lessens the current by a feature of 10. So if your line power was about 115 volts, the secondary voltage would certainly be about just 11.5 volts. On the other hand, if the line voltage power was 130 volts, the low power transformer will be producing 13 volts. Line voltage might also differ with time of day and when other electrical heaps are on tract systems. Consequently is very imperative to calculate the line voltage at the power transformer simultaneously that the transformer would also be in use.

The voltage will keep decreasing the further the current travels. So as to recompense this and the differences in line voltage, some transformers provides numerous output voltages. These low voltage transformers are usually known as multi-tap transformers and might provide voltage outputs varying from 10 volts to 14 volts. This is proficient by having guides coming off the main or secondary coil at different points close to the end of the coil to generate various other different voltages. This is a precious feature for any system designer desiring to have superior control over light output and other lamp life.

On the other hand, it is very imperative to know that transformers could not steady voltage variations. They just move the current at a fixed ratio and don't experience changes. There are tools to manage such difficulty, but it is naturally too costly and pointless for landscape lighting tools. Low voltage transformers are provided with and with no cabinet. Those with no enclosure are associated to an electrical box and wired straight to the line voltage source.
