Wat is ompoolbeveiliging?
It can still happen that electronic devices are connected incorrectly. A reverse polarity protection ensures that the devices are safe when connected incorrectly. It protects the electronics from breaking down. If the battery terminals are connected incorrectly, the reverse pole protection will not allow the voltage to pass through. For example, if the plus is connected to the minus and the minus to the plus. The consequence of not letting the signal through is that the connected device will not be damaged. If the poles are connected correctly, the protection will of course not do anything. The device or lighting will then operate as it normally would. So it does not affect the operation of the devices when it is connected properly. It only offers a piece of protection for the electronic device.
Safety in LED lighting
A reverse polarity protection can also be useful when connecting lights. You do not want your lights to break down because they are connected the wrong way round. There are lamps for which it does not matter whether you connect the plus and minus correctly. These lamps are not polarity sensitive. Examples of these are License plate light and markeerverlichting. The situation is slightly different with LED lighting. LEDs are namely oriented in one direction and therefore work in one direction. This type of lighting is therefore already reverse-polarised by nature. The signal is never transmitted in the opposite direction. The bulb can therefore not just break down when it is connected the wrong way round.
