Q 1.How about your experience?

A.We have our own professional factory and R&D department & more than 10 years producing experience

Q 2. What's your advantage ? 

A. We have complete set of machines such as ,injection molding machines and punchers,

with these,we can make by ourselves from the inside parts to outside.

It greatly increases the efficiency and saves the cost.

Q 3. How's the delivery time ?

Q:What is the effect of the open contact of the AC contactor and the pushbutton switch?
Press the start button, the coil is energized, and the auxiliary contact is sucked together. The coil also communicates with the control line through the auxiliary contact.
Q:Get the method of the relay time parameter
In the process of contact will produce bounce, and finally to achieve a stable state, during which the microcontroller data collected or 0 or 1. Set the sampling period of the microcontroller 0.01ms, the data collected by the microcontroller address value multiplied by the sampling period, that is, the required action time. [2]
Q:What is the energy saving function of traditional contactors?
once the current becomes smaller so that the resulting electromagnetic force is not enough to overcome the reaction force of the spring, the contactor can not keep the closing state ,
Q:The Role of Virtual Instrument Technology in the Parameter Detection of Switchgear Cabinet
In the literature, a time parameter detection circuit is mentioned. The main components of the circuit are single-chip microcomputer
Q:What is the difference between the contactor and the relay?
Electromagnetic relays and contactors, their working principle should be said to be the same
Q:What about the release device and the contactor and the circuit breaker?
Circuit breakers can be used to distribute power, not frequently start the asynchronous motor, the power lines and motors and other protection, when they have a serious overload or short 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:How to use Star Triangle to start contactor orders and processes
Coil circuit in the KMY contactor Contact, when the KMY moving contact is closed, KMY moving contact is broken, after a pre-set delay, the time relay dynamic contact KT off, cut off the coil KMY, the circui
Q:Seeking Star Triangle to start the contactor on and off the order and process
In the control circuit, the first branch has a time relay coil KT, when it is energized, the dynamic contact contact will be delayed open
Q:What is the traditional AC contactor contact that does not vibrate?
And permanent magnet AC contactor suction, completely rely on permanent magnet force to achieve, once completed the pull, the voltage fluctuations will not affect the permanent magnetism
