Tips: What is an over and under-voltage protector?
An over and under-voltage protector, also known as an overvoltage and undervoltage protection device, is a device used to protect electrical equipment from excessive voltage levels or voltage fluctuations that exceed predefined thresholds.
An overvoltage protector is designed to detect and respond to voltage spikes or surges that exceed a predetermined upper limit. When an overvoltage event occurs, the protector triggers a protective mechanism to limit the voltage to a safe level, divert the excess voltage to the ground, or disconnect the equipment from the power source to prevent damage or malfunction.
On the other hand, an undervoltage protector is used to monitor the voltage level and detect when it drops below a predefined lower limit. When an undervoltage condition is detected, the protector can take actions such as signaling an alarm, initiating backup power sources, or disconnecting the equipment to prevent damage or operational issues caused by low voltage.
These over and under-voltage protectors are commonly employed in various applications such as residential electrical systems, industrial machinery, data centers, and sensitive electronic equipment. They help ensure that the voltage supplied to the equipment remains within a safe and operational range, protecting against both overvoltage and under-voltage situations that can lead to equipment failure or damage.
It's important to note that the specific features and functionalities of over and under-voltage protectors can vary depending on the application, industry standards, and the specific requirements of the electrical system being protected.
