Can you double up LED drivers?
For extra-long runs you can even link up multiple LED drivers on the same circuit by adding amplifiers. Some led lights like LED ground and marker lights are constant current and require a 350ma or 700ma supply. These types of products also require specific voltages so it’s important to get them to match.
Can you run LED drivers in series?
The requirements of a lighting application often dictate what type of circuit can be used, but if given the choice, the most efficient way to run high power LEDs is using a series circuit with a constant current LED driver. Running a series circuit helps to provide the same amount of current to each LED.
What are the different types of LED drivers?
There are two main types of drivers, those that use low voltage DC input power (generally 5-36VDC) and those that use high voltage AC input power (generally 90-277VAC). LED drivers that use high-voltage AC power are called Off-Line drivers, or AC LED drivers. In most applications using a low voltage DC input LED driver is recommended.
How is the maximum number of LEDs I can run determined?
The maximum number of LEDs you can run from a single driver is determined by dividing the maximum output voltage of the driver by the forward voltage of your LED (s). When using LuxDrive drivers, you determine the maximum output voltage by subtracting 2 volts from your input voltage.
Why do I need a constant current LED driver?
In the beginning, we mentioned using a constant current LED driver because these power modules can vary their output voltages to match the series circuit. As LEDs heat up their forward voltages change, so it’s important to use a driver that can vary its output voltage, but keep the same output current.
How many LEDs can you run in a parallel circuit?
Rule number 2 from the series circuit bullet points proves that 12V dc isn’t enough voltage to run all 9 LEDs in-series (9 x 2.98= 26.82V dc ). However, 12V dc is enough to run three in-series (3 x 2.98= 8.94V dc ). And, from the parallel circuit rule number 3 we know that total current output gets divided by the number of parallel strings.
