LED phase indicator: diagram and model overview. How to make the phase indicator yourself

When installing the outlet or switch in the apartmentIt is necessary to have a phase indicator at hand. These devices differ from each other in the power of the generator. Also, the models have their own frequency and threshold resistance. A lot of phase indicators are presented on the market.

They are produced with two or three clamps. The pulse width of the models does not exceed 90%. When choosing a modification, it is important to pay attention to the protection class. In order to learn more about phase indicators, it is necessary to consider the scheme of the device.

Phase indicator: circuit

The scheme of the phase indicator includeswire generator. To determine the voltage there is a damper. Sensors in devices are installed with different reducibility. For some elements, the LED is used with an amplifier. If we consider modifications with a display, then they have a microcontroller. To protect the device from overloads, capacitors of operational or impulse type are used.

Homemade modification

If necessary, the LED phase indicatorcan do by yourself. First of all, a qualitative wire generator is selected for this. The output voltage should be at least 12 V. It will also require a damper to assemble the device. There are different types on the market, and they are quite different in sensitivity. If we consider a simple model, then it is more expedient to select an element with a resistor. The microcontroller for the phase indicator will need multi-channel type. At the end of the work, the LED is fixed, as well as the clamps.
