When installing a socket or switch in an apartment, you must have a phase indicator on hand. These devices differ from each other in terms of generator power. The models also have their own frequency and threshold resistance. There are quite a few phase indicators on the market.
They are produced with two or three clips. The pulse duty cycle 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, you need to consider the device circuit.
Phase indicator: diagram
The phase indicator circuit includes a wire 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. Capacitors of operational or pulse type are used to protect the device from overloads.
Homemade modification
If necessaryLED phase indicator can be made by yourself. First of all, a high-quality wired generator is selected for this. Its output voltage must be at least 12 V. Also, a damper is required to assemble the device. There are different types on the market, and they vary quite a bit 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 clamps.
