PWM 0-30s Soft Start/Soft Stop Variable Speed DC Motor Speed Controller Battery Low Voltage Protection Recoverable Overcurrent Protection PWM Switch Control 9-70V 40A

【5~70V Configurable Battery Low Voltage Protection】This pwm dc motor controller is an advanced version of 2.0A, including the functions of 2.0A.In addition have built-in battery low voltage detection, to prevent the battery from over-discharging and thus affecting the battery life, when the battery is lower than the set value, it will stop working;

【variable speed pedals support】This dc motor speed controller supports variable speed control pedals, and also supports maximum speed settings in this mode to set the maximum safe speed your child needs;

【0~30 Seconds Configurable Soft Start/Stop Time】This power wheels speed controller have soft start/Soft Stop can Reduce the impact of starting inrush current, prolong the life of the motor, and enhance the safety of children when upgrading children's electric vehicles;

【Maximum 35A peak current automatic protection】After use this dc speed controller ,When the peak current exceeds 40A or the motor speed controller's continuous current exceeds 30A, the PWM will be automatically reduced, and the fuse will never need to be replaced;

【More Design Margin】 There are 4 PWM CMOS tubes and 1 Freewheel diode. More safety current margin is reserved for more complex environments.

Effect Demo

This dc motor controller has made a special optimized design for power wheels motor upgrade，but also suitable for speed regulation of other DC motors such as fan speed controller.

After upgrading a child's electric car with a drill battery, the child's laughter makes parents feel that it's all worth it. However, children often stop playing until the battery is exhausted, which often leads to the battery not being able to charge normally. This dc motor controller have built-in 5~70V Configurable Battery Low Voltage Detection, to prevent the battery from over-discharging and thus affecting the battery life, when the battery is lower than the set value, it will stop working;

Variable Speed Pedals Support
This pwm dc motor speed controller has independent variable speed control pedal interface and soft start/soft stop interface. Variable speed control pedal input interface voltage range can be configured within 0~5V by key and can be configured to reverse. Supports variable speed pedals and is compatible with other sensor inputs;

The Variable Speed pedals Interface is compatible with SH1.0 3 pin (pin pitch 1mm), and our corresponding pedals already include a connector compatible with this interface, no need to buy it separately. But if you don't plan to use the pedals provided by us, you may need to prepare this type of connector separately.

How to Integrate with Original Vehicle Wiring

Warning:

1. Please make sure that the positive and negative poles of battery correspond to "power+ power-". Reverse connection can damage the product or battery, and in serious cases can cause a fire.
2. The module can only drive brushed motors, not brushless motors.
3. The module is a DC motor speed controller and cannot be connected to AC power.
4. The module is a DC Motor Speed Controller, not a Voltage Controller.
5. This module adopts aluminum alloy shell to dissipate heat and has no built-in fan, so it is small in size. When the power used.
6. The input power must be greater than 1.5 times the rated power of the motor (note: the input voltage and the rated voltage of the motor must be consistent.)
7. If there is a forward-reverse circuit regulator on the children's car, please be sure to connect this module between the power supply and the forward-reverse circuit regulator of the children's car. Otherwise, The module may be damaged.
8. The maximum continuous working current allowed by this module is 30A. When the external short circuit occurs, the module will maintain a continuous current of 30A. At this time, if the rated current of other lines or loads outside the module is less than 20A, the external equipment or load will be damaged, burnt, and fire. If the rated current of the external line and load is less than 20A, it is recommended to use an external fuse.
9. Due to the compact design of the product, the product does not have a built-in fan, So it need a heat dissipation gap around it when installed. At the same time, when using high power, especially when using full power, if the product heats up seriously, please use it with an external fan. (When used for power wheels, it will only generate heat slightly, no external fan is needed).
