## Description

PWM Soft Start/Soft Stop Variable Speed DC Motor Speed Controller Recoverable Overcurrent Protection PWM Switch Control 9-70V 35A

## Features

- 【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;
- 【Soft Start/Soft Stop Support】This power wheels speed controller reduce the impact of inrush current when starting and stopping suddenly, prolong the life of the motor and gear, and enhance the safety of children when upgrading children's electric vehicles;
- 【Max 35A Peak Current Automatic Overcurrent Protection】 when the peak current of this speed controller for electric motor exceeds 35A or continuous current exceeds 20A, The PWM will be automatically reduced to maintain the output continuous current of 20A. When the current is reduced, it will automatically recover. Fuse will never need to be replaced;
- 【Mounting Holes】This dc motor controller can be installed directly using screws without external mounting positioning accessories.
- This variable speed controller have 0~100% duty cycle adjustment. 16.23khz frequency. 9-90V input voltage support, have working indication,Aluminum alloy shell. Stronger and more durable. Can bu used in power wheels replacement parts,pwm fan controller,power wheels replacement parts

## Questions & Answers

**Q: Is there an equation for the capacitor value to determine soft start time? I want to make it very small as 3 sec is too long.**
A: Hello, the calculated value is usually inaccurate, because the resistance and capacitance have errors, only by experiment. Reducing the value of C13 and C15 can reduce the softstart time. At present, they are all 10uF, you can change them to 5uF, and the withstand voltage is above 10V. At the same time, you can also try the 2.0B module, the softsart time of the 2.0B module can be adjusted through button configuration. The adjustment range is 0~30s, and the step is 0.1s.

**Q: Where an I download the instructions?  I've misplaced the one that came with the controller.**
A: Hello, please contact me via amazon message or email, I will send you a copy

**Q: I'm trying to install this on a power wheels hurricane which has a 2 speed forward and 1 speed reverse. will it work with the variable pedal?**
A: Hello, you can achieve one forward and one backward, refer to the answer video in the link: https://www.amazon.com/ask/questions/Tx24I1TKJW7JPHH/ref=ask_dp_dpmw_al_hza.
        When you use the variable speed pedal, the speed is controlled by the variable speed pedal, and the control range is 0~100%. So the device with two gears is meaningless and can be removed

**Q: Can this be used with 2 20v dewalt batteries in series with 2 775 motors with the pwm duty cycle down to 24v?**
A: Hello, the voltage range of the pwm module is very wide. The voltage of 20V Dewei batteries connected in series is 40V, and the working voltage of 40V is still within the normal working voltage range of pwm. But the pwm module only adjusts the duty cycle, and the output voltage is still 40V, so you need to confirm the working voltage range of your 755 motor. Generally, the allowable voltage range of 24V type 755 DC motor is 12~30V. 40V is a bit high, please check with the 755 motor supplier for details. If your motor is also connected in series, then yes, but if your motor and battery are connected in series, it seems pointless to do so? It is recommended to connect two Dewei batteries in parallel, and then connect the two motors in parallel.
