How to Select and Use Automotive Relays

Usually, we install relays in circuits with high currents, mainly because the capacity of the control switch contacts is not sufficient. If an intermediate relay is not installed, the control switch contacts are easily burned out, which affects the normal operation of the entire circuit. Usually, we determine and select the size of the relay contact capacity based on the size of the load power. The contact capacity of a relay refers to the maximum current allowed to pass through the relay contacts operating at rated voltage, known as the relay contact capacity. The size of the contact capacity is the voltage applied to the contacts and the ability to pass through the contact current, calculated by the load power, The capacity of the contact should not be exceeded (this calculation is very simple, the current is obtained by dividing the load power by the voltage). For example, automotive relays have many nominal capacities, ranging from a few A to around 150A, and their applications are manifested in various circuits. Improper selection and use can lead to certain consequences. Usually, there are two situations that we see: one is using small materials to make a big difference, and what is using small materials to make a big difference? It is a dangerous method of using small capacity relays in circuits with high current flow. Once powered on, the relay will instantly burn out, and in severe cases, it may cause safety hazards. Another method is to use large capacity relays in circuits with small currents, which is called "big talent small use". This use cannot be said to be impossible, it can only be said that there is no need to use a butcher's knife to kill pigs, as it is economically wasteful and unnecessary. In summary, when using various automotive relays, it is best to calculate the current based on the load power and choose a relay with a slightly larger capacity for optimal use.

2019 Hong Kong Autumn Electronics Exhibition

The annual Asian electronics industry autumn event, Electronic Asia, was held in Hong Kong Convention and Exhibition Centre from October 13 to 16, 2019. The 2019 Hong Kong Electronics Fair (Autumn Edition), jointly held at the same time, saw the top ten buyers coming from mainland China, Taiwan, the United States, South Korea, Japan, India, the United Kingdom, Russia, Australia, and Germany. The conference also organized over 1000 buyer groups and arranged for over 5700 international buyers from over 3900 companies to visit the exhibition, making it a leading exhibition in the Asian electronic manufacturing industry. The exhibition focuses on precision electronic production equipment and manufacturing assembly services, showcasing core technologies in electronic manufacturing.
