Mô Đun Điều Khiển Động Cơ Bước 2 Chiều 12v 24v 7a 160w L298

"Features:
1. Double H bridge, which can drive two DC motors, single 7A current, high power;
2. Wide voltage input 6.5V ~ 27V
3. Signal optocoupler isolation input, IO port can be directly controlled, without interference;
4. Undervoltage protection, to prevent instantaneous high-current burned module;
5. High-power TVS and electrostatic discharge circuit, inhibit the transient interference pulse and static, enhanced EMC performance, stable and reliable product, industrial design.

Specifications:
1. Power supply voltage 6.5V-27V, power supply must not be connected to or over 27V, otherwise it may burn out the module, it is recommended that the power input in series 15A fuse.
2. Dual motor interface, each rated output current 7A, peak current 50A, the motor interface must not short-circuit, the proposed series 10A fuse.
3. Control signal voltage 3-6.5V, respectively, is the enable signal and the positive inversion control signal.
4. Enable signal terminal (ENA) input PWM adjustable speed, PWM frequency range 0-10KHZ, PWM minimum pulse width 10us.
5. Working temperature -25 ℃ -80 ℃.
6. Installation hole diameter: 3mm, attention should be paid to prevent short circuit on the back of the circuit, you can add insulation pad or copper column to raise the circuit board.

Precautions:
1. Drive power must not be reversed, the proposed power connector in series 15A fuse, the voltage should be between 6.5 ~ 27V. If the voltage is over-voltage, power-on may burn the drive module.
2. It is recommended that the rated output current of the power supply should be at least 2 times of the rated current of the motor so that the power supply can not supply the required voltage when the motor starts. Off the output lead to the phenomenon of motor pause.
3. Do not short-circuit the motor interface, or may burn the driver module, the proposed electrical interface in series 10A fuse.
4. In the forward and reverse switch when the need to brake 0.1S above and then reverse, not in the motor has not stopped when the commutation, or it may damage the drive.
Suitable for motor parameters:
Rated voltage of 24V motor, the appropriate identification of rated power 115W and below or rated rated current 7A the following motor full length of work
Rated voltage 12V motor, the appropriate identification of rated power 40W and below or rated rated current 7A the following motor full length of work
