How to choose the best LED power supply for your LED strip lights?
Step 1. LED lighting power supply or LED light adapter? Small or Large LED Lighting Driver?
The difference between choosing an LED strip light power supply or LED power adapter is the power of the LED strip light. LED power adapters are less powerful than LED switching power supplies.
LED Strips come in rolls of 5 meters/16.4 feet. One or two LED strips can be used in a power adapter. However, multiple LED strips should be used with a switching LED power supply. If you want simple wiring and installation, a power adapter is a good choice.
If you need to install more LED strips with longer running time, it's better to choose switching power supply, because generally, switching power supply has higher power output. And it can provide enough power for multiple or long running LED strips.
If you want a beautiful layout and hide the power supply, please choose mini power supply.
When you need led strip lights temporarily but afraid of not convenient to carry, choose a lithium battery. It is very convenient.
Power Distribution Box CCTV Power Supply It is the control center to command the reasonable distribution of electric power among the components in the power supply line, which is suitable for schools, hospitals, factories, workshops, families and so on.
Step 2. Select the correct voltage, power and current.
The size of the wattage and whether the current and voltage are stable will directly affect the performance and service life of the power supply.
The working output voltage of LED strip light is 5V, 12V, 24V. if your strip light is 5V, you need to choose 5V power supply. Choose 12V LED power supply for 12V light strip and 24V LED power supply for 24V light strip.
The rule for calculating the power LED strip is 80%. This means that the total power of your LED strip is 80% of the power supply. This has the advantage of increasing the life of the led transformer. If your LED strip is 100W, you will need a 125W power supply. Remember the 80% rule when choosing a power supply.
If you don't adjust the current, the current consumption will be increasing. And high current consumption will lead to excessive heat inside the power supply, which can damage the power supply and lead to failure.
Step 3. Dimmable LED power supply or non-dimmable power supply?
If your strip light is SCR dimmable, you should choose SCR dimmable power supply. Dimmable led strip lights are generally controlled by controlling Touch wall panel function buttons to control the brightness of the strip, but there are also remote controls to adjust the light.
There are many types of LED strip lights Dimmer, 0/1-10V dimmer, Triac dimmer, DALI dimming system and DMX512 system.
0/1-10V dimming is easy to apply and has a good dimming effect.
DALI dimming system has strong anti-interference ability, can feedback faults, single-lamp control makes the control more flexible.
DMX512 powerful control function to the building lighting, night lighting, studio, all kinds of stage to bring rich lighting effects. And DMX512 needs special wiring layout and certain programming ability to set the basic colors and scenes.
Choose the appropriate dimming power supply for your dimmable LED strip.
Step 4. Do you need a waterproof or rainproof power supply?
Your installation location will affect whether you choose a waterproof or rainproof power supply.
If you are going to install the LED strip light in outdoor or humid environment, you need to pay attention to the waterproof problem, it is better to choose waterproof or rainproof power supply.
However, if your power supply is installed in an indoor or dry environment, you can choose a non-waterproof power supply.
The quality of products on the market varies. In this case, all you need to do in order to choose a good product is to look for UL certified power supplies.
Improper use of the power supply or other reasons may lead to problems such as overheating and short-circuiting, so for safety reasons, make sure that the power supply you buy has these protective features.
Follow these steps to choose the right power supply for your project. With the right power supply, you can not only use the LED strip well, but also reduce the risk of use and improve user safety.
