    How to judge the quality of European-style terminal blocks?

    At present, the specifications of the terminal blocks on the market are similar. Whether the products are good or bad, we first look at the appearance. Generally, the plastic surface is smooth and free of burrs and no gaps. The color is pleasing to the eye without yellowing and dullness; the pins ar... read more

    Shunt principle

    A shunt is actually a resistance with very small resistance. When a direct current passes through it, a voltage drop is generated for the display of a direct current ammeter. The DC ammeter is actually a voltmeter with a full scale of 75mV. DC ammeter and shunt are used together. For example, the cu... read more

    Shunt

    The shunt is used to measure the DC current. It is made according to the principle that the DC current produces voltage at both ends of the resistance when it passes through the resistance. It is made of insulating ceramics with uniformly distributed holes. The protective gas from the welding torch ... read more
