Gongkar AC 110V/220V fan temperature control speed controller

* Functional overview: Industrial-grade technical scheme, using single chip microcomputer with ARM core as the main control chip, with temperature display, suitable for communication. The 110V /220V/&50HZ/60H fan is used for temperature control and speed regulation, and the speed regulator controls the output voltage through the detected temperature, thus realizing. The current fan speed control, the higher the temperature, the faster the speed, when the temperature is lower than the start-up temperature, the fan is shut down or the minimum speed is maintained. Speed, higher than the starting degree, the fan runs at a low speed. If the temperature continues to rise, the fan speed will also rise slowly. When the temperature rises to When the full-speed temperature is set, the fan will run at full speed, and when the temperature starts to drop, the speed of the fan will also drop automatically, so as to circulate. Work; This product can be used not only for fan speed regulation, but also for other extended applications based on temperature control AC voltage output.

*. Product performance/technical parameters

1. Industrial-grade scheme, integrated with high-voltage and high-current SCR chip, with stable performance, which can be safely used in outdoor and industrial scenes.

2. Wide voltage design, adaptive 110V /220V/50HZ/60HZ AC, maximum driving current 3A.

3. With LED digital tube indication, the temperature can be displayed in real time, and various parameters can be set conveniently with keys.

4. Built-in fuse, RC surge absorption current and power supply short-circuit protection circuit.

5. Support two working modes: no fan shutdown mode and fan shutdown mode.

6. It comes with a high-temperature early warning relay output (dry contact). When the temperature exceeds the set high-temperature threshold, the relay will pull in. (Relay parameters: maximum cut-in voltage 250V, maximum current 2A)

7. The temperature range is -9~99℃, and the temperature control accuracy is 1℃

8. Guide rail installation, suitable for all kinds of outdoor cabinets.

*Instructions for use

1. Connect the power supply of the governor and the wiring of the fan according to the interface instructions.

2. Plug the temperature probe into the governor and fix the metal part of the probe in the heating part.

 3. Turn on the power supply, and the governor will adjust the fan speed according to the temperature detected by the temperature probe.

 4. Pay attention to check whether the wiring is correct during installation. * Take the factory default temperature range of the governor as an example. The factory default temperature range of the governor is L=30℃ and H=50℃, which should be checked. When the current temperature is greater than or equal to 30℃, the governor adjusts the speed of the fan in linear proportion. When the temperature rises, the speed of the fan increases Will also speed up, when the temperature is greater than 50℃, the fan becomes full speed, when the temperature drops to 28℃(L-2), the governor is closed.

Fan

 * The power supply voltage of the governor should be consistent with the rated voltage of the fan. How many volts is the fan, and how many volts is the power supply!

 * when multiple fans are connected, the fan voltage connected to the governor must be the same, and it is not possible to connect one 110V and one 220V V.

*More extended applications

Based on the output of temperature control and voltage regulation, it can be extended to applications such as dimming and temperature regulation.
