What is the suitable driver or power supply for my LED strip?
The driver you need for a specific LED strip depends on the type of LED strip you have. Every LED strip requires a voltage. In most cases, this is supplied by a driver, adapter, or transformer. However, not every adapter is suitable for every LED strip. Therefore, in this article, we will explain what you need to consider when choosing the right adapter/driver/transformer for your LED strip.
LED strips are usually supplied in the following voltages: 12 volt, 24 volt, or 220-230 Volt. They often come in 5-meter rolls that you can shorten with scissors. The power/wattage per meter varies greatly depending on the type of LED strip. There are many different kinds of strips. Below, we explain what you need to take into account.
Step 1: Voltage
Check the packaging or specifications of the LED strip to see what voltage it requires. Then, choose a driver with the correct output voltage.
Step 2: Wattage per meter
The power rating is very important. Every LED strip has a power rating per meter, regardless of whether it is a 12-volt, 24-volt, or 220-240 Volt LED Strip. This is all expressed in wattage W/M (Per Meter). This is because you can cut LED strips to the desired length, making it useful to know how much wattage the LED strip consumes per meter.
Step 3: Strip length
The length of the LED strip is also certainly important. This ultimately determines the total wattage and which driver you need for your LED strip.
We always maintain a 10% safety margin, as loading a driver to its maximum capacity does not promote its lifespan and significantly reduces the risk of overheating.Step 4: Connecting the LED Strip
Check the polarity of the LED strip; the phase and neutral wires of the strip must be connected correctly to the driver. The red cable is the phase wire, black cable is the neutral wire. The LED driver indicates where to connect which wires using V+ or V-. V+ stands for Voltage + (Phase wire) and V- stands for Voltage – (Neutral wire).
LED strip power supply calculation:
Wattage p/m x number of meters of strip = ……..total wattage strip
(Wattage p/m x number of meters of strip) * 10% margin/voltage strip = ……… Ampere load

Wiring diagram LED Driver 12V/24V
How do I connect an LED driver to an LED strip? The image below shows you how this works. When you want todim an LED strip wirelessly , you will need a receiver with a remote control .The image below shows an LED dimmer; this is the receiver recommended for most LED Strips
LED strip driver with a standard wall dimmer
If you wish to dim a 12-volt or 24-volt LED strip using a standard wall dimmer, this is easily achievable. The only component you will need is a dimmable driver, which you install between the wall dimmer's power circuit and the LED strip. The 12-volt or 24-volt LED strip will then dim without any issues.
