Digital protector and oscillator SM516 Somo

A power shield is a device that sits on the input path of a power outlet if there is a voltage or ampere or power consumption for any reason (such as power outages at a power plant or power plant or transmission lines, lightning and natural disasters, theft of power cables Urban, overconsumption, etc.) out of standard range, disconnects power line and reconnects power line to electrical equipment after specified time if standard conditions arise. Prevent damage to the device. The operating range of the voltage and ampere, as well as the time required to re-pass the electrical current, depend on our electrical device, because the amount and sensitivity of each electrical device varies. For example, the power consumption of a packer varies with a washing machine or vacuum cleaner or a gas cooler or mixer or a lamp with a conventional lamp.
