Question:

What is overvoltage relay? What is low voltage relay?

What is overvoltage relay? What is low voltage relay?

Answer:

Overvoltage relay is when the voltage value is greater than the action value, the armature is sucked, moving contact closure, relay action; when the voltage is lower than the return value when the armature is released, moving contact open, relay return

When the voltage is higher than the return value, the armature is sucked, the dynamic contact is opened, and the relay returns. The voltage is lower than the return value, the armature is released and the movable contact is closed.

Relays are very important in electrical engineering and automation of low voltage devices. There are many types of relays. According to different classification methods, relays can be divided into different categories. For example, according to the working principle of the relay can be divided into electromagnetic relays, induction relays, electric relays, thermal relays and electronic relays. You can look at the Boer Power, set years of technical accumulation and continuous core research and development advantages, relying on unique patented technology, intelligent power distribution system solutions, energy management, and one-stop power environment facilities solutions for data center facilities And other areas of energy efficiency are very prominent.
