Welded power led driver

Because they can control the electrical current, a constant current driver is best for LED downlights or high powered LEDs. A constant voltage driver is designed for LED lights that need a fixed voltage (of either 12 or 24v) but have a current that's already being regulated by another safety device, like a resistor.

What is a LED power driver?

LED drivers (also known as LED power supplies) are similar to ballasts for fluorescent lamps or transformers for low- voltage bulbs: they provide LEDs with the electricity they require to function and perform at their best.

Can I connect 2 LED drivers together?

Connecting multiple LEDs to a constant current LED driver in parallel is not recommended. Constant current LED drivers are used to power LEDs that have no internal current regulation. When you connect multiple LEDs to a constant current LED driver in parallel, you run the risk of reducing the life span of your LED's.

Is an LED driver just a power supply?

The LED driver is a self-contained power supply which has outputs that are matched to the electrical characteristics of the LED(s). This helps avoid thermal runaway as the constant current LED driver compensates for the changes in the forward voltage while delivering a constant current to the LED.

How do I choose an LED driver for my LED?

5 Important Factors When Buying LED Drivers

Output Voltage / Current. First, consider the voltage requirements of your light.
Input Voltage / Current. Next, consider the voltage supply of the location you'll be using your light. ...
Max Wattage. Lastly, consider the wattage requirements of your light. ...
IP Ratings.

What is the life expectancy of an LED driver?

The driver is the heart of the LED light, and driver life can range from 10,000 to over 50,000 hours, depending on the design features, heat sink efficiency, capacitor construction, and overall quality.

Is an LED driver just a transformer?

Although similar in operation, LED Drivers are different from transformers. Whereas transformers convert an “input” voltage to an “output” voltage, both functioning on an Alternating Current, LED Drivers convert AC to DC and subsequently supply a constant current to the LED.

What is the difference between LED power supply and LED driver?

LED power sources that provide a “constant-current” output have typically been referred to as LED drivers. In the past, AC-DC power supplies that provided a regulated “constant-voltage” to LEDs were referred to as LED power supplies. Today, the terms “LED driver” and “LED power supply” are used interchangeably.

How many types of LED drivers are there?

The main two types of LED drivers are constant current drivers and constant voltage drivers.

How do I connect my LED driver to my power supply?

Next you're going to connect. Your power source to your LED strip light you will connect your red

Are LED drivers AC or DC?

LEDs are designed to run on low voltage (12-24V), direct-current electricity. However, most places supply higher voltage (120-277V), alternating current electricity. An LED driver rectifies higher voltage, alternating current to low-voltage, direct current.

Can I use any power supply for LED lights?

You will either need a constant current LED driver or a constant voltage power supply (or a combination of both) in order to make your LEDs work properly.

How do you match LED driver to light?

Use an LED driver with at least the same value as your LED(s). The driver must have a higher output power than your LEDs require for extra safety. If the output is equivalent to the LED power requirements, it is running at full power. Running at full power may cause the driver to have a shorter life span.

Do LED drivers need ventilation?

LED drivers need to be mounted in a ventilated space. Access to the driver needs to be provided for general maintenance purposes.

Do I need a driver and a transformer for LED lights?

Yes, all LED lights do require a bulb driver to operate but it is not always necessary to purchase these separately.

What happens when a LED driver fails?

If the LEDs have failed the output voltage of the LED driver will be at its rated output (maximum voltage output for a constant current LED driver). The ELG-240-C2100A is a constant current LED driver, to it will be up at around 115V DC. If the LED driver has failed there will be zero volts on the output.

Can you fix an LED driver?

LED Driver Replacement is a difficult process. When an LED fixture fails you need to either purchase a new fixture or replace the driver. In most scenarios it's the LED driver that needs replacement (LED components have a longer shelf life).

Do LED drivers wear out?

While the light function of an LED may last for years, drivers can give out much sooner. This is why we recommend name brand LED bulbs for the home, especially those with 25,000 hour rated lives.

Can I use 12v transformer for LED?

LED drivers and electronic transformers for retrofit LED lighting are not interchangeable. They differ in output and load compatibility i.e. which LED lights they will work with. The fundamental difference between the two is that LED drivers output DC while electronic halogen transformers output 12VAC.

What wattage LED driver do I need?

It's also advised the total wattage of all bulbs combined doesn't exceed 80% of the transformer's wattage. So if you choose to power 4 x 4W MR16 bulbs (16W total) from one driver, you'll need a 20W driver. If you want to power 4 x 6W MR16 bulbs, you'll need a 30W transformer, and so on.
