Price introduction of Hongfa relay

In our life, especially in student dormitories, schools generally limit our electricity consumption, and some do not, but the useful electricity is still limited. At this time, some people use relays, which can slowly output larger current with smaller ones, and there are many brands of relays. Today, we will learn about the price of Hongfa relay and how to measure the pull-in voltage and pull-in current.

How to measure the pull-in voltage and pull-in current?

Find an adjustable regulated power supply and ammeter, input a set of voltages to the relay, and connect the ammeter in series in the power supply circuit for monitoring. Slowly raise the power supply voltage, and when you hear the pull-in sound of the relay, write down the pull-in voltage and pull-in current. In order to be accurate, you can try several times and take the average. Measuring discharge voltage and discharge current: it is also the connection test mentioned above. After the relay is pulled in, the power supply voltage gradually decreases. When the relay is released again, write down the voltage and current at this time, or try several times to get the average discharge voltage and current. In general, the release voltage of relay is about 10 ~ 50% of the pull-in voltage. If the discharge voltage is too small (less than the pull-in voltage of110), it will not be used normally, which will threaten the stability of the circuit and make the work unreliable.

Relay is actually a switch element with isolation function, which is automatic and can be used not only in schools, but also in remote control equipment or communication. The use of relays is also common in the control of many automation devices. The relay can not only expand the control range, but also input multiple signals into the relay. After comprehensive calculation, the comprehensive control effect is achieved. I believe that after learning about Bian Xiao's introduction, you will have a better understanding of the price of Hongfa relay and other related introductions.
