Motor test measurements usually require ammeters to be equipped with multiple shunt units to solve the problem of ensuring the desired measurement accuracy over a larger measurement range. At this point, the rated voltage drop of all shunt used must match that of the ammeter (e.g. 75 mV).

Common-mode choke: In the common filter, usually only one common-mode choke is installed, and the leakage inductance of the common mode choke is used to generate an appropriate amount of differential mode inductance,

What is a shunt resistor? A shunt resistor is a resistor with a small resistance value for measuring DC current. It is made according to the principle of a voltage drop across the resistor when the DC current passes through the resistor, and converts the current signal into a voltage signal for DC current detection.

​Due to its special function of shunt resistors, when used in precision electronic products, such as instruments, meters, and measuring devices, the resistor should be selected with special emphasis on accuracy. If the accuracy is not enough, it may cause the size of the shunt current to pass through a large Difference value projection, which directly leads to larger measurement errors, which would be meaningless measurements. In the same way, for other precision electronic information technology products, because the development of Chinese enterprises has high requirements, it is necessary for us to choose resistors with high precision.

In order to increase the cohesion of the company's employees, strengthen their sense of belonging, and promote employees' understanding and communication, so that each employee can truly feel the warmth of the big family of China Science and Technology after stressful work, the company organized employees with the theme of "Thanksgiving for you" Birthday party activities, to celebrate the birthday of employees in November, share happy moments!
