What are LED drivers and what are they for?

Current is a complex thing and not all electronic devices can be connected to the current coming from the socket. Light emitting diodes, i.e. LEDs, do not tolerate the alternating current of the socket and would be destroyed immediately. To prevent this from happening, they need an operating device or ballast that provides the current from the socket as it is needed by the LED.

This device is our driver (sometimes also called power supply). The LED driver takes over the important task of converting the conventional alternating current into direct current and delivering it with a constant current in the desired voltage so that the LEDs can also use it. The driver also provides protection against short circuits, overvoltage, overload and overheating.

DC power supply or LED drivers with constant-current

Now these drivers are also available in different versions, depending on how many and which LEDs are to be operated with them. In our case this is simple: all our drivers are exactly matched to the LED chips of our range.

Important driver tip

If the LEDs are connected to a rather inferior driver, they tend to flicker. This can be observed when you film them with a camera. Not constant light is not very helpful when it comes to plant growth. Therefore a high quality driver is urgently needed. With the MeanWell drivers we have found such drivers and recommend them to others.

Finding the right LED driver

The most important thing when finding the right LED driver is that it can cope with the number of connected LEDs and their number of watts. Depending on how many of them the driver is supposed to supply with power, it has to deliver a corresponding output. Just take a look at how much output current and voltage you want or should drive the LED chips and how many of them. The sum must be equal to (or less than) the power of the driver.

Also there is the possibility to choose between different package types. At a certain power the manufacturers tend to put the driver into a metal socket anyway. The alternative is plastic.

For LED drivers we trust in MeanWell.

Nothing is more important for electronic devices than trustworthy and reputable manufacturers. At MeanWell we have found one. Since 1982, the internationally active company has been producing high-quality solutions for the power supply of electrical appliances, including our popular LED drivers.
In particular 3 of their series are suitable for our purposes:

The ELG series: solid middle class
The ELG series is available in the 150 and 200 edition. The numbers stand for the approximate number of watts for which the drivers are suitable. This results in a LED chip count of 2-4 per driver. The devices are also characterized by an efficiency of over 90% and are, of course, also capable of dimming the light.

H, like high performance: the HLG series

If you need more power, you best use drivers of the HLG series. They stand for high performance, because with their up to 480W output power they convert the current that drives up to 9 LED chips of 50W each. Therefore, these models are perfectly suited for our larger LED kits, which carry up to 8 chips.

The LPC series for Far-Red and single modules

For additional Far-Red LEDs or single modules, we recommend the LED drivers of the LPC series. The output power of the MeanWell LPC-35-700 is so high that it can drive up to 21 lamps with the deep red light colour. Even more moderate LED chips are operated flawlessly.
