How to Choose an Over Voltage Relay? Understand the Necessary Conditions for Over Voltage Relays
Working principle and characteristics of over voltage relay (relay) When the input quantity (such as voltage, current, temperature, etc.) reaches the specified value, the controlled output circuit is turned on or off. It can be divided into two categories: electrical quantity (such as current, voltage, frequency, power, etc.) relays and non-electrical quantity (such as temperature, pressure, speed, etc.) relays.
