36V DC Under Voltage Monitoring Relay 2 C/O Output Contacts LED Indication
The voltage drop will damage the lines and electrical equipment. For example, if the motor is worn down or blocked, an overcurrent of several times the rated current will be generated and the motor will be burned out. When the voltage recovers, the self-start of a large number of motors will cause the voltage of the motor to drop drastically and cause damage. The voltage that causes the motor to wear out is called the critical voltage. When the line voltage is reduced to the critical voltage, the action of protecting the electrical equipment is called undervoltage protection. Its task is mainly to prevent the equipment from being burned due to overload.
Generator undervoltage protection mainly considers the following two purposes:
1. When the generator is in the power supply state, when the voltage is too low, it will be disconnected from the power grid to avoid adverse effects on the electrical load.
2. When the generator is in the cut-off state, when the voltage is too low, it cannot be switched on to ensure the power supply quality.
Undervoltage protection appliances are contactors and electromagnetic voltage relays. In the electrical control circuit of the machine tool, only a few circuits are specially equipped with electromagnetic voltage relays, and most of the control circuits do not increase the under voltage protector because the contactors have the undervoltage protection function. Generally, contactor (or voltage relay) contacts are released when the grid voltage drops below 85% of rated voltage.
And this product is used with contactor
