Chassis Fan Speed Controller DC 12V 24V 48v 6A PWM temperature control speed regulation RS485 serial TEMP LED display
1. Product introduction
Industrial-grade technical solution, using ARM core single-chip microcomputer as the main control chip, with a temperature display
frame, which can be directly embedded on the panels of various chassis 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 machine 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
1. Industrial-grade solution, using STM8 series single-chip microcomputer as the main control chip, stable performance
2. Wide voltage design, support 12V/24V/48V four-wire PWM fan/motor direct access, maximum drive current 6A
3. With LED indication, it can directly indicate the working status of the governor
4. Power supply anti-reverse connection protection design, the power supply will not burn the board if it is connected reversely
5. Start and full speed temperature can be set freely, support two working modes of minimum speed and shutting down the fan
6. Support fan failure detection, with buzzer alarm and fan failure NPN signal output
7. Standard modbus-rtu protocol, support RS485 serial port to set various parameters and query fan status
8. RS485 serial TVS anti-surge design, the default serial parameters are 9600bps, 8, N, 1
9.100% shutdown of all 4-wire fans
10. PWM output frequency 25Khz, amplitude 5V
3. Specification and size
3.1, motherboard 70mm*46mm, mounting hole size: 63mm*40mm
3.2, display 79mm*42mm*26mm, installation opening 76mm*40mm
