Undervoltage 12V DC Current Monitoring Relay 2 C/O Output Contacts

Low voltage protection
Also known as pressure loss protection and under voltage protection. When the power supply voltage disappears or falls below a certain value, a protection measure of the circuit can be automatically disconnected. Its function is to avoid accidents caused by the sudden start of the equipment when the voltage recovers; at the same time, it is prevented from being damaged due to bare operation under low voltage. At low voltage, the equipment can only maintain its operation when the current is increased. The current increases, and the heat rises naturally. In general, the equipment is damaged and the fire is caused when it is heavy. For important protection objects, the device consists of voltage relays, time relays, and circuit breakers, and the protection performance is more accurate. For general low-voltage devices, commonly used fuses, contactors, and loss of voltage (undervoltage) releases are used as protection devices.
Low-voltage protection refers to the use of low-voltage protection relays connected in parallel across the power supply. When the voltage is low, it automatically trips to disconnect the circuit-breaker switch. Low-voltage practice installation: There are thermal relays, fuses, relays and other low-voltage equipment.
When the power supply bus voltage of the motor is reduced for a short time or the interruption resumes, in order to prevent the motor on the line from self-starting at the same time, the power supply voltage is seriously reduced, and the low voltage protection is usually installed on the secondary motor. When the power bus voltage is low to a certain value, the low voltage protection action will cut off the secondary motor to restore the power bus voltage to a sufficient voltage to ensure the self-start of the important motor.
