1. Product introduction

Industrial-grade technical solution, using ARM core single-ch microcomputer as the main control ch, with a temperature display frame, which can be directly embedded on the panels of various chais cabinets. The speed governor controls the fan speed through the detected temperature. The higher the temperature, The faster the speed, when the temperature is lower than the starting temperature, the wind hine stops or maintains the minimum speed,

When it is higher than the starting degree, the fan runs at a low speed. If the temperature continues to rise, the fan speed will also increase slowly.

When the temperature rises to the set full-speed temperature, the fan will run at full speed. When the temperature starts to drop, the fan speed will also automatically drop, thus circulating work;

The speed governor supports RS485 serial communication, through the serial port protocol, you can control the fan speed, configure/query the governor parameters/status, the serial port instructions follow the modbus-rtu protocol, and the fan speed can be adjusted from 0-100%

2. Product performance/technical parameters
