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
When connecting lighting, reverse polarity protection can also come in handy. You certainly don't want your lighting to break because it's connected the wrong way. There are lights where it doesn't matter if you connect the plus and minus correctly. These lights are not polarity-sensitive. Examples of these are license plate lighting and marker lights. With LED lighting, this is a bit different. LEDs have a specific direction and work in one direction. This lighting is naturally already reverse-poled. The signal is never transmitted against the direction. So, the lamp cannot simply break if it's connected the wrong way.
