Bảng Mạch Điều Khiển Tốc Độ Động Cơ Không Chổi Than 120w 5a

Note! ! !
1. Power supply and drive products are power products, please read the manual or product description carefully before use.
2. The positive and negative poles of the power supply cannot be reversed, otherwise it will be damaged.
3. The module has a large current of 5A, 120W, derating to use when it is severely heated to avoid overheating and burning.

Highlights:
·It has four modes: manual control, automatic control, host computer control and serial port control.
·With host computer software, you can control the motor or set automatic control parameters through the host computer software, and the set parameters will not be lost after power failure.
·The control circuit and the drive circuit have optocoupler isolation, which has strong anti-interference ability.
·With motor running status indicator light, with different colors, indicating the current running status.
·Choose a rotary potentiometer with a switch, which can be used as a power switch and convenient for speed adjustment. The frequency adjustment adopts a dial switch, which is simple and convenient to operate.
·External port is reserved, which can be connected with external control switch or TTL communication. After the software is set, the program is loaded into the module.
·The running state can be quickly switched, no noise, and stepless speed change is possible.

Parameter:
1. Input voltage range: DC5V-26V. (No protection against reverse connection)
2. Drive motor current: 5A, instantaneous current 50A. (No short circuit protection, it is recommended that the output end is connected in series with a 6A fuse)
3. Standby current: <5mA.
4. Speed ​​regulation range: through the rotary potentiometer, the speed is 0%-100% stepless speed regulation.
5. Frequency range:
[Manual control] There are 8 ranges of 300Hz-10KHz.
[Automatic, software, serial port control] 300Hz-10KHz can be adjusted arbitrarily.
Note: The lower the selected frequency, the greater the fluctuation of the input power supply.
6. Serial communication: TTL level. (Not directly connected to the 232 interface of the computer)
7. Working temperature: -40℃-85℃.
8. Dimensions: length, width and height 67*39*15mm.
9. Introduction of signal interface:
[VCC] 5V power supply output port, which can supply power to customers' 485 to TTL modules, USB to TTL modules, etc.; power supply current is 20mA.
[TX, RX] TTL communication interface, connected to the upper computer software.
[CW, CCW, STOP, SD] ​​Forward, reverse, stop, brake button outlet, when suspended, it is high level 5V, can be connected to the button to GND, equivalent to the button on the module, or connected to 5V MCU IO control , Low level trigger (to ensure reliable trigger, low level time>100ms, just set high after trigger; if it is always low level, it is also possible, but before the next action, be sure to set the port high; dial 4 When the code switch is set to the ON position, it is in automatic control mode, the button or this port is inva
