Q: How to connect the DC contactor to the circuit?: and some sites are dangerous people can not go to the power cord can not run everywhere, which requires remote control, high current places, dangerous places with contactors We are in a safe place to control

Q: Basic classification of AC contactors: The contactor is mainly composed of electromagnetic system, contact system, arc extinguishing system and other parts.

Q: What is the power contactor: The main contact is generally only normally open contacts, and auxiliary contacts often have two pairs of normally open and normally closed contact, small contactor is often used as an intermediate relay with the main circuit

Q: What is the main structure of the contactor?: The power of the AC contactor is derived from the magnetic field generated by the AC core coil. The solenoid core is made of two "mountain" shaped silicon steel sheets, one of which is fixed with a coil and a working voltage. select

Q: Permanent magnet AC contactor working principle: The permanent magnet, which is fixed in the contactor linkage mechanism, is connected with the variable polarity soft magnet which is solidified on the base of the contactor so as to achieve the purpose of pulling

Q: What are the classification of contactors?: arc time is relatively long, in order to fully release the circuit The remaining energy. The combustion of the arc produces high temperature and strong light, the surface of the contact has a serious ablation,

Q: What does the contactor lock mean?: so after the start of the contactor point closure point, the coil can stop from the button Get the power, so that the formation of a self-preservation circuit.

Q: How to get the relay time parameter: The literature refers to a relay time parameter computer detection method, which uses self-developed acquisition board, which is mainly composed of single-chip and its peripheral circuit

Q: Similar terms for contactors and relays: The main function of the relay is the signal detection, transmission, transformation or processing

Q: Contactor mainly by the drive system, contact system, arc and other components.: contact system: contact is the implementation of contactor, including the main contact and auxiliary contacts
