Connecting a Transformer for LEDs
LEDs require a power source to operate properly. A driver for LED lights supplies this power, converting alternating current (AC) to direct current (DC). The constant and uninterrupted supply of electricity prevents overheating, colour changes and degraded performance. These drivers also offer thermal shutdown protection to switch off lighting when the temperature reaches too high.
A transformer is a device that converts mains voltage to low voltage, often 12V DC. It is used in light fittings to take the high voltage of the mains and step it down to a level that LED lights can use safely.
It also can be used to regulate the voltage of a lighting circuit, making it ideal for dimming. It can be powered from a standard wall switch or plug-in system, and it allows you to control the brightness of your LEDs through a dimmer or other conventional wall control.
When choosing a transformer for your project, you’ll need to consider its output voltage and current capabilities. These can be specified in amps (A) or milliamps (mA), and should match the current requirements of your LEDs.
The output voltage of a transformer varies as the current of the transformer changes, and it is usually expressed in watts. The higher the wattage rating of your LEDs, the more powerful the transformer will need to be to provide sufficient power for them.
A transformer is an important part of any LED installation, and a good quality one can be crucial to the success of your project. Whether you’re installing LED lights in your home, business or public space, make sure you buy the right transformer for your needs to ensure maximum efficiency and long life.
Connecting a Transformer for LEDs
A transformer can be used to connect multiple single-colour or white / single-colour LED strips together, as long as the total wattage of each strip matches the wattage output of the LED transformer. You’ll need a connector-block for this purpose, which you can get from any electrical supplier. You’ll need to wire the starter-lead (+ve and -ve) of each strip to the connector-block’s input terminals, and the output terminals to each of the outputs of the connector-block.
If you’re planning to run more than two white / single-colour LED strips, it is advisable to purchase a multi-output connector-block with more than one output. It will save you money, because you won’t have to buy several different power supplies for each strip.
When selecting a transformer for your project, be sure to choose one that is IP rated to protect your LEDs from water and dust. It should be able to withstand high temperature spikes, such as from power surges caused by thunderstorms. A higher rating will also help your transformer last longer, as it’s less likely to overheat.
