3 in 1 dimming circuit would drain 0.1mA per model. Dividing the rated current of the dimmer by the 0.1mA, and we could know how many units can be controlled by one dimming device. For resistance dimm […]

Most strip lights contain a resistor in series, as the result, constant voltage LED driver must be used in this kind of application. We recommend to choose dimmable constant voltage LED drivers such a […]

3 in 1 dimming is the most commonly applications used in LED dimming with the feature that it does not have to work with any specific dimmer. The only thing that has to be verified is that whether the […]

In the MEAN WELL LED power supply product line, the XLG optional products have the highest lightning surge withstand capability, which can reach 10KV/line 6KV/line-to-ground. If higher SURGE capabilit […]

MW LED power supply does not have parallel “current sharing” function so it is not suitable for parallel connection. For high power requirement, please select higher wattage power supply or divide LED […]

First calculate for required voltage by combining total LED forward voltage and driver voltage drop of 2V. LED forward voltage of each strip = 3.5V x 12pcs = 42V Driver circuit required voltage = 42V […]

First of all, the LED power supply must be able to work in constant current mode. LED forward voltage of each strip = 3.5V X 12pcs = 42V LED lamp total current requirement = 0.7A X 4 strips in paralle […]

Depending on circuit design, there could be different operational problems.   See below: Boost mode driver IC: The startup voltage of such driver IC is significant lower than the total LED forward vol […]
