[Mini DC fan manufacturer] The wind is not strong, just effective
The main function of the DC fan of the mini DC fan manufacturer is to dissipate heat. The fan is a high-speed motor, but when the DC fan has been working for a few years, it suddenly stops working. The products that have been working for a long time here are inverters, switches, etc. , The system will rise in temperature in a short period of time. If it is left unattended for a long time, it may cause excessive temperature rise and damage to the product. Therefore, it is necessary to monitor the DC fan. When the DC fan of the mini DC fan manufacturer does not turn We can know quickly.
u003cbru003eCurrently, there are two types of monitoring methods for DC fans: alarm sensor and speed sensor. The alarm sensor can be used to give an alarm signal when the speed of the DC fan is below a certain threshold, and the speed signal output can be realized. Real-time monitoring of fan speed.
u003cbru003eThe alarm signal output from the DC fan circuit of the mini DC fan manufacturer has two states, 'high level' and 'low level'. The meaning of the two levels is generally based on the positive logic system, and the high level is expressed 'Fault\u003cbru003e
