Q:Nvestigation on Detection Technology of Relay Parameters of Single Chip: Measurement function is mainly realized by software programming, in the industrial computer as the core components of the hardware platform support, through the LabDes software development platform programming instrument testing functions.

Q:What is the noise-free function of traditional contactors?: The traditional AC contactor is closed by the coil power to make the silicon steel sheet to produce electromagnetic force

Q:What does the contactor NC ON mean?: insulation shell and accessories, all kinds of springs, transmission, short circuit, terminal, etc

Q:What about the release device and the contactor and the circuit breaker?: and undervoltage failure can automatically cut off the circuit, its function is equivalent to the fuse switch And a combination of overheat relays and the like.

Q:The difference between electromagnetic contactor and AC contactor: C contactor is also a kind of electromagnetic contactor, because the AC contactor is the use of alternating current to let the coil produce magnetic field (magnetic flux), so that contactor to pull.

Q:Computer-centric development trend: Compared with the traditional oscilloscope detection, the contact arc arc voltage waveform is accurate

Q:What is the difference between a release, a contactor and a circuit breaker?: Contactor in the broad sense refers to the use of electric current in the coil to generate a magnetic field, the contact closed to achieve the control of the load of electrical appliances.

Q:Use Star Triangle to start contactor's order and process method: Press the stop button SB2, the coil KM is out of power, the main contact and the self-locking contact are disconnected, the motor stops.

Q:What is the contactor's formula?: The setting current of the thermal release should be equal to the rated current of the controlled load.

Q:What is the formulation of the contactor?: contactor number of auxiliary contacts, and contactor installation options
