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

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

They are produced with two, 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 phase indicator circuit includes a wired 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 installed. To protect the device from overloads, capacitors of operational or impulse type are used.

Homemade modification

If necessary, the LED phase indicator can be made independently. 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. A microcontroller for a phase indicator will be required by a multichannel type. At the end of the work, the LED is fixed, as well as the clamps.
