The 8 Common Pitfalls When Purchasing LED Power Supplies!
Most LED light manufacturers have their own power supply units and LED driver for their LED products. Some customers would buy LED strips and power supplies separately. This is because there isn’t a single standard of design that would fit all LED products.
There are many LED power supply manufacturers that produce different quality products, they use different materials and components, the quality of the SMPS switching power supply on the market is uneven. There may be some problems had, some pitfalls will have when customers purchase LED power supply.
There are 8common pitfalls you may meet as below:
1. Complexity, making it difficult to use
There isn’t any instruction or it can’t know how to connect from the product. End-user doesn’t know how to connect to LED strip lights. The LED power supply isn’t the same as the LED driver, LED drivers are installed inside the LED products when the LED lights are finished.
2. Output isn’t full load, no enough power for the LED strip light
The LED power supply is constant voltage because the output keeps stable to 12V or 24V or 5V or 9V or 18V any voltage customer need.
In many cases, some factories just see the wattage rating on any power supply, they don’t care about other details. The high wattage LED products can be dissipated a lot of heat, so a larger fan is needed too for high wattage LED power supply. if the power supply doesn’t match the corresponding power of the LED light strip, it will burn out, also, it will hurt the LED strip lights.
Also, if the output isn’t full load, the LED lighting is dark than the intrinsic lumens of the LED strip light.
3. It costs more power after several months
If the power supply is of worse quality, it can use no problem. Some end users like to buy a cheap power supply, but they may find the power supply costs more power than the good quality power supply.
4. Power input and voltage regulation
Input voltage for some countries is 100–120vac like the USA, they can’t use a power supply or led strips with input voltage 200–240Vac. but they may get a power supply at input 200–240vac if the supplier didn’t pay attention to it. Besides, if the voltage regulation is bad, they can only input voltage 100–120vac and never reach 120–140vac or even worse to 80–90vac.
5. Unstable working environment
If the power supply work in the input changes frequently, it will be unstable. In this case, the power may shut off or reduce wattage if any voltage changed in time. Also, it needs a wide input range, for example, in Brazil, their input isn’t stable, so the led power supply must use a wide input range of 100–240Vac.
6. Safety, poor insulation, and isolation
Some power supplies may break even fired in working because the power supply used poor components, it is so terrible! It can’t bear the environment of humidity, dust, etc. it makes the power supply won’t work.
7. Noisy power supplies
Noise generated on the power supply leads to a high noise level on the output of LED lights. Noisy power supplies are also not good for our ears too. Especially when the power supply is installed in the bedroom, the noisy sound is easy to affect sleep at night!
8. Inadequate protection from short circuit, over current, and overheating
For general LED power supplies, it should have the over-temperature, over-current, over-voltage, over short-circuit protection function. The power supply does not have adequate short-circuit protection, overvoltage protection, and overcurrent protection. When the power supply is in the process of use, the temperature is too high, overheating protection doesn’t work or takes a too long time to take action, Or the instantaneous current is too large, over-current protection doesn’t work; When the instantaneous input voltage is too large, but the over-voltage doesn’t work. For these situations, the power supply can not immediately stop working, so it will be easy to burn some components to cause damage to the power supply, they can not be used anymore, it will request to change a new one.
In general, these are the 8 common pitfalls when purchasing LED power supplies from the market. All these lead to poor performance and failure of LED lighting system soon. It is not good for LED strip light because it will reduce the lifetime of PSU’s
When purchasing LED power supplies it is important to be aware of the common pitfalls. With so many options on the market, how can you determine which one will best fit your needs? The following are some common mistakes that people make when buying LED lights or power supplies.
How do I choose an LED power supply?
The LED lighting project or LED shop or LED retailer may need to buy LED power supply from a Chinese supplier directly. When choosing an LED power supply, the most important point should keep in mind the location where it will be used. For instance, indoor lighting is much different than outdoor lighting. If your light will be installed outdoors take into account that it may be exposed to rain or other weather conditions that indoor lights would not require.
For indoor use, you can choose a non-waterproof power supply For outdoor use, you can choose a Rainproof power supply or a waterproof power supply, waterproof can be used in pools underwater. Also, dimmable power supplies are a good choice now.
