Problems solved by technology
However, the existing fan controller has a single function and cannot monitor the working status of the fan, such as the working current and working voltage, nor can it prompt and alarm at the first time when the fan is working abnormally.
In addition, the circuit structure of the internal circuit of the existing fan controller is simple, and the anti-interference ability is poor, which leads to poor working stability of the fan controller and increases the probability of damage to the fan during operation.

Description
technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a fan controller circuit. Background technique [0002] The fan is a relatively common product on the market, mainly used for ventilation and temperature adjustment. The fan controller is used to control the working status of the fan, such as controlling the start and stop of the fan, and controlling the output power of the fan. However, the existing fan controller has a single function, and cannot monitor the working status of the fan, such as the working current and working voltage, nor can it prompt and alarm at the first time when the fan is working abnormally. In addition, the existing internal circuit of the fan controller has a simple circuit structure and poor anti-interference ability, which leads to poor working stability of the fan controller and increases the probability of damage to the fan during operation. Contents of the invention [0003] The purp...
