Taidacent RS485 Modbus RTU Automatic Cabinet Fan Dimmer Switch PC Case Fan Controller PWM Temperature Control CPU Cooling Fan Governor with Relay (RS485 with Relay)

1. Industrial-grade solution, using ARM series single-chip microcomputer as the main control chip, with stable performance.

• Industrial-grade technical solution, using ARM core single-chip microcomputer as the main control chip, with temperature display, the 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 fan will stop Or maintain the minimum speed.
• When it is higher than the start-up speed, the fan will run at 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. The speed of the fan also decreases automatically, and it works in this cycle; the governor supports RS485 serial port communication, through the serial port protocol, the fan speed can be controlled, and the parameters/status of the governor can be configured/queried.
• The serial port instructions follow the modbus-rtu protocol, and the fan speed is 0-100 % adjustable, with fan fault detection function, when the fan stops abnormally, the relay output signal
• Wide voltage design, support 12V/24V/48V four-wire PWM fan/motor direct access, maximum drive current 8A
• The temperature of start-up and full-speed can be set freely, and it supports two working modes of minimum speed and shutdown fan
