DC 12V~48V 100A High Power Dual Channel DC Motor Drive Module Board Optocoupler

100A DC motor drive Module High Power motor governor speed Control Dual H-bridge power supply 12V~48V 36V 24V optocoupler isolation

This module uses a 10M high-speed optocoupler to isolate the input signal, effectively preventing the interference signal of the drive board from interfering with the control board, making the system more stable and reliable.

This module can be used to drive general DC motors with a maximum current of up to 100A . It is unmatched by general integrated motor drives. Therefore, it is very suitable for robot competitions, chariot competitions, and Freescale competitions.

Of course, this motor drive module is also very suitable for novices who are learning motor control, because its control method is very simple, see the following description for details

Features of drive module:

1. The basic components of the drive module body are patches, high integration, well-designed board layout, very beautiful, small size, onboard two high-power DC motor drive, the size of the drive module is only 80mm*70mm;

2. The large heat sink can effectively dissipate heat for the drive module when the current is large, and maintain the stable performance of the module;

3. When driving the motor, the maximum rated current of the module can reach 100A and the on-resistance is only 0.0015 ohm;

4. The switching frequency is high, up to 60KHZ, which effectively avoids the unpleasantness caused by the low frequency of the commissioning motor;

5. The control interface is very simple:

When A1.A2=0.0, it is brake;

When A1.A2=1.0, it is forward rotation;

A1.A2=0.1 is reverse;

PA is PWM wave input (motor speed adjustment);

G is the common ground pin with the control board (B road is the same control);

6. Both 3.3V and 5V microcontrollers can control this module, and only one motor power supply (12V~48V)
