I want to make a overvoltage and undervoltage protection circuit. Overvoltage should trip at 460VAC and undervoltage at 180VAC. Any idea how to implement it.
ElectroPhysics said:Actually the circuit should operate normally between 180 to 260VAC. If input voltage goes above 260VAC or below 180VAC it should cut input supply. The circuit must be able to monitor input voltage upto 460VAC. A relay should be used to pass the mains voltage in normal operating mode.
The problem is that I have to make power for comparators and relay from the mains voltge. And for such a wide input voltage range it is very difficuilt to do that.

OVP (Overvoltage Protection) and UVP (Undervoltage Protection) for mains input are safety features that protect electronic devices from high or low voltage levels in the power supply. They prevent damage to the device and potential safety hazards.
OVP and UVP work by continuously monitoring the voltage level of the incoming power supply. If the voltage level exceeds or falls below a certain threshold, these protection features will activate and shut off the power supply to the device, preventing any damage.
OVP and UVP are important because they protect electronic devices from dangerous voltage levels in the power supply. Without these features, devices may experience malfunctions, overheating, or even catch fire, leading to potential safety hazards.
While OVP and UVP are not required for all devices, they are highly recommended for devices that are sensitive to voltage fluctuations, such as computers, televisions, and other electronic equipment. It is always better to have these protection features in place to prevent any potential damage.
In most cases, OVP and UVP are built-in features that cannot be disabled. These safety features are essential for protecting the device and should not be tampered with. However, some devices may have the option to disable them, but it is not recommended to do so.
