What is the role of shunt resistance Shunt Resistors is an important function of current sensing in electronic systems, but its complexity is often underestimated. Accurately measuring current flow is far less easy than measuring voltage, and it is even more difficult when trying to measure current ... read more
The safety relay is a combination of several Latching Relays and circuits in order to complement each other's abnormal defects and achieve the complete function of the correct and low malfunction relay. The lower the error and failure value, the higher the safety factor. Therefore, it is necessary t... read more
1. The principle of current transformer selection and inspection 1) The rated voltage of the current transformer is not less than the rated voltage of the line at the installation point; 2) Calculate the current IC according to the primary load to select the current transformer change; 3) Select the... read more
What is the working principle and function of the relay? The use of the relay in our home is still very important. It can provide the most basic living security for the home life, but we must pay attention to the use of the relay to avoid unnecessary trouble. First, What is the function and principl... read more
The role and working characteristics of the relay. The relay is an electronic control device. It has a control system (also called an input loop) and a controlled system (also called an output loop). It is usually used in automatic control circuits. A kind of "automatic switch" that uses a small cur... read more
