Product Parameters

1. The Power Supply Voltage Is 6v-36v (If the Voltage Is Too Low and the Load Current Is Large, It Is Easy to Damage the Module, So the Circuit Board Is Marked as 9-36v). The Power Supply Must Not Be Reversed Or Exceed 37V, Otherwise the Module May Be Burnt out, it Is Recommended to Connect the 20A Fuse in Series at the Power Input.

2. The Driver Does Not Heat Dissipation Rated Current 12A, Rated Current 12A ~ 15A Need to Do Simple Heat Dissipation, 15A ~ 20A Need to Do Thick Heat Dissipation. (Simple Heat Dissipation-for Example, after Mat 1mm Thermal Silicone Pad under the Module, Use 5mm Copper Cylinder to Fix the Module to the Device Wall)

3. the Control Signal Interface (Orange) Can Provide Users with 5V, the Single Chip Microcomputer Does Not Need Additional Power Supply, and the Power Supply Current Is 0.5A.

4. Control Signal High Level Voltage: 2.0V ~ 5.5V, Compatible with 3.3V and 5V TTL Level;

Low Level Voltage of Control Signal: 0V ~ 0.8V, and 0V When Suspended;

When the Control Signal Voltage Is 5V, the Control Signal Current Is 50UA.

5. Effective Range of PWM: 0.1%~;

PWM Signal Frequency Range: 0~100KHz (Recommend 20KHz);

PWM Small Effective Pulse Width: 200ns.

6. Working Temperature-25 ℃-80 ℃.

7. Product Size: 55*55 * 25mm (Length, Width and Height).

8. Mounting Hole Diameter: 3mm.

1. Motor with Rated Voltage of 36V

Mark Rated Power 300W Or below Or Mark Rated Current 12A Motor for a Long Time Full Work without Heat Dissipation;

Mark Rated Power 300W ~ 370W Or Mark Rated Current 12A ~ 15A Motor Need to Do Simple Heat Dissipation Treatment;

Mark Rated Power 370W ~ 500W Or Mark Rated Current 15A ~ 20A Motor Need to Do Thick Large Dispersion Heat Treatment;

2. Motor with Rated Voltage of 24V

Mark Rated Power 200W Or below Or Mark Rated Current 12A Motor for a Long Time Full Work without Heat Dissipation;

Mark Rated Power 200W ~ 250W Or Mark Rated Current 12A ~ 15A Motor Need to Do Simple Heat Dissipation Treatment;

Mark Rated Power 250W ~ 330W Or Mark Rated Current 15A ~ 20A Motor Need to Do Thick Large Dispersion Heat Treatment;

3. Motor with Rated Voltage of 12V

Mark Rated Power 70W and below Or Mark Rated Current 12A below the Motor for a Long Time Full Work without Heat Dissipation;

Mark Rated Power 70W ~ 90W Or Mark Rated Current 12A ~ 15A Motor Need to Do Simple Heat Dissipation Treatment;

Mark Rated Power 90W ~ 120W Or Mark Rated Current 15A ~ 20A Motor Need to Do Thick Large Dispersion Heat Treatment;

(This Driver Does Not Heat Dissipation Rated Current 12A, Rated Current 12A ~ 15A Need to Do Simple Heat Dissipation, 15A ~ 20A Need to Do Thick Heat Dissipation. The Rated Power Marked on the Motor Generally Refers to the Output Power, Considering the Work Loss of the Motor, So the Motor Efficiency Should Be Considered When Calculating the Rated Current, and the Rated Current = Rated Power/Rated Voltage/Efficiency)

Usage:

1. Use Single Chip Microcomputer to Control Motor Rotation Wiring Method

1. The Power Supply Voltage of the Driver Should Be between 6-36v. If the Voltage Is over-Voltage, the Driver May Be Burned after Power-on; If the Voltage Is Too Low and the Load Current Is Large, the Driver May Also Be Burned. It Is Recommended to Connect 20A Fuse in Series at the Power Supply.

2. When Switching Forward and Reverse, Brake for More than 0.1S before Reversing, Otherwise the Drive May Be Damaged.

3. Because the Control Signal Line Is Very Fragile, Any Signal Line (Orange Wiring Terminal) of the Control Signal Cannot Be Connected with the Wiring of the Power Supply Or Motor Interface during Use, Otherwise It Is Very Likely to Burn the Driver, and It Is Difficult to Repair.

4. When the Driver Is Powered down, Do Not Rotate the Motor Quickly, Otherwise the Electromotive Force Generated by the Motor May Burn off the Driver. If the Application Requires the Motor to Be Rotated Quickly When the Driver Is Powered down, It Is Recommended to String a Relay at the Motor Interface of the Driver, and the Relay Coil and the Driver Share the Power Supply. In This Way, When the Power Is down, the Relay Will Disconnect the Driver from the Motor.

5. The Driver Should Be Connected to the Motor before Power on, Otherwise the Fuse Or Driver May Be Burned.

6. the Motor Interface Must Not Be Short-Circuited, Otherwise the Fuse Or Driver May Be Burned.

7. Pay Attention Not to Damp the Driver, Do Not Short Circuit the Components on the Driver Board, and Do Not Touch Pad the Pins and Pads of the Components by Hand.
