In our lives, especially in student dormitories, schools generally limit our electricity consumption. In some cases, although our electricity consumption is not limited, there are still restrictions on useful electric power. , then some people use relays at this time. This kind of relay can use smaller ones to slowly output larger currents. There are also many brands of relay products. Today we will take a look at the prices and prices of Hongfa's relays. How to measure pickup voltage and pickup current.

How to measure the pull-in voltage and pull-in current ?
Get an adjustable voltage-stabilized power supply and an ammeter, input a set of voltages to the relay, and insert an ammeter in the power supply circuit for monitoring. Slowly increase the power supply voltage, and when you hear the relay closing, note down the closing voltage and current. For accuracy, you can try several times and find the average. Measure the release voltage and release current: It is also connected and tested as mentioned above. When the relay pulls in, gradually reduce the supply voltage. When you hear the release sound of the relay again, write down the voltage and current at this time. You can also try multiple Several times to obtain the average release voltage and release current. Under normal circumstances, the release voltage of a relay is about 10 to 50% of the pull-in voltage. If the release voltage is too small (less than 1/10 of the pull-in voltage), it cannot be used normally, which will threaten the stability of the circuit. Makes work unreliable.
In fact, a relay is a switching element with an isolation function. This switching element is also automatic. It is not only used in schools, but also in remote control equipment, communications, and the control of many automatic equipment. , the use of relays is also very common. The relay can not only expand the range of control, but also input multiple signals into the relay, and achieve a comprehensive control effect after comprehensive calculation. I believe that after understanding the editor's introduction, everyone will have a better understanding of the price of Hongfa Relay and other related introductions.
