1. Installation direction If the installation direction is consistent with the direction of the relay's impact resistance, the performance of the relay can be fully utilized. It is recommended to make the impact direction perpendicular to the movement direction of the contact and armature, which can... read more
Does the relay work make a sound? The answer is yes. The role of the relay is very wide, and there are many types of relays. We can see the relay in circuit control. The role of the relay is to use it as a switch. Pulling in will make a sound, but only mechanical relays will make a sound. Let's take... read more
1. Installation direction If the installation direction is the same as the direction of the shock resistance of the relay, the performance of the relay can be fully exerted. It is recommended to make the impact direction perpendicular to the movement direction of the contact and armature, which can ... read more
The power regulator thyristor regulator is the abbreviation of thyristor rectifier element. It is a four-layer structure high-power semiconductor device with three PN junctions, also known as thyristor. It has the characteristics of small size, relatively simple structure and strong functions, and i... read more
1. Electronic over-current protection function: Cut off the over-current measured by the load current detection CT to protect the thyristor components.Maintain constant voltage characteristics through voltage feedback: The voltage control function provides a stable output and achieves linear charac... 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
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
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
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
