When installing an outlet or switch in an apartment, you must have a phase indicator on hand. These devices differ among themselves in the power of the generator. Also, models have their own frequency and threshold resistance. There are quite a few phase indicators on the market.
They are made with two, three clamps. The impulse rate 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 circuit 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 overload, capacitors of operational or pulse type are used.
Homemade modification
If necessary, the LED phase indicator can be done independently. First of all, a high-quality wired generator is selected for this. The output voltage indicator for it should be at least 12 V. Also, a damper will be required to assemble the device. Various types are available 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 require a multi-channel type. At the end of the work, the LED is fixed, as well as the clips.
