1. Before using the relay, check whether there is any damage during transportation, that is, set it at the first setting point, turn the movable system in the direction of the magnetic pole by hand, and then release it, the movable system should be turned back to the original position Until it stops... read more
The DC contactor adopts a modular design, which can assemble the number of contact paths required by the customer and the form of contacts required by the customer (normally open, normally closed and converted) with the fewest parts; the contact breaking voltage of this series of products is high , ... read more
1. DC contactor It is generally used to control DC electrical equipment. DC current is applied in the coil. The operation principle and structure of DC contactor are basically the same as that of AC contactor. Because it can quickly cut off the AC and DC main circuits and can be frequently connected... read more
Low-voltage electrical appliances are conventionally divided into the following two categories according to the relationship between the systems used: 1. Low-voltage distribution appliances Low-voltage distribution appliances are mainly used in low-voltage power supply systems. When the circuit ha... read more
Commonly used electromagnetic relays include current relays, voltage relays, intermediate relays and time relays. The intermediate relay is actually a kind of voltage relay, but it has a large number of contacts with large capacity, which plays the role of intermediate amplification. Commonly used e... read more
