LED RGB controller

In the case of RGB light sources, sources with a constant positive of the power supply (control by the negative of the power supply) should be used. The module has two local inputs: one to connect a button operating in the same way as in dimmers (short press switches on/off, longer press dims/brightens) and the other, a service one, to change the color of light without the use of a touch panel. Using the touch panel it is possible to fully control brightness, color and the times of brightening and dimming. The module requires connecting an independent 12 V DC power supply with a power matched to the connected LED load. The correct polarity of a power supply is very important. A reverse connection may damage the connected light source (the module is protected). There are two types of RGB modules: the older model from 2012 and a newer model from 2013. A newer model has an additional relay that switches on the 12 V power supply. The general principle of operation is based on the fact that RGB lighting is not switched on permanently and there is no reason for the 12 V power supply to be permanently switched on. The module is powered by a 24 V system power supply and the 12 V power supply is only switched on if required.
