Rated operating voltage Refers to the voltage required by the coil when the relay is working normally. Depending on the type of relay, it can be either an AC voltage or a DC voltage. 2. DC resistance Refers to the DC resistance of the coil in the relay, which can be measured by a universal meter. 3.... read more
The basic structural components of the electrical connector include: 1.Contact The contact is the core part of the connector to complete the electrical connection function. The contact pair is generally composed of a male contact and a female contact, and the electrical connection is completed by th... read more
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
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
Mutual inductor, also known as instrument transformer, is the general name of current transformer and voltage transformer. It can turn high voltage into low voltage and large current into small current, so it can be used for measurement or protection system. Its main function is to convert high volt... read more
