Feature

●WIDE VOLTAGE: Wide voltage input 7-70V (70V is the maximum working voltage, please leave a margin when using)so that adapt to more DC motors. The maximum output current is 30A, which can provide enough driving capacity for the motor.
●FUNCTIONS: The PWM DC motor speed controller has the functions of running, stopping and braking. The adjustable potentiometer flexible cable can be separated, the cord length is 15cm.
●CIRCUIT OPTIMIZATION DESIGN: Wide range of duty cycle adjustment, stable motor adjustment without noise and vibration, with power indication, stable circuit design, precision welding switch, stable and can be used for a long time.
●SPEED CONTROL KNOB: The motor speed control switch has a knob with switch function. It is easy to use and can be directly connected to the motor, which can control the motor speed from 0% to 100%.
●FEATURES: PWM frequency is 12KHZ. This adjustable PWM motor speed regulator with aluminum housing adopts imported high-voltage MOS tube, three pressure 100V high-frequency low-resistance capacitors, and automobile fuses. The parameters are accurate, not easy to heat up, and easy to replace. It is suitable for DC brushed motors.


Description

Enmja 7-70V 30A PWM DC Motor Speed Controller, can be directly connected to the motor and adjust the potentiometer to adjust the motor’s speed.

Specifications:

Color: Silver

Condition: 100% new

Packing Included:

-1pcs DC Motor Speed Controller

Instructions for Use and Precautions:

1. Make sure that the positive and negative connections between the power supply and the governor are correct before turning on the power. Reverse connection may burn the circuit board. Do not touch the heat sink with the wiring, or it may burn the circuit board.

(Motor) There is no need to distinguish between positive and negative. If the direction of rotation is wrong, please change the two wires of the motor.

2. Note that this is not a power supply module, it must be connected to the motor to adjust the speed. Without the motor, the output of the multimeter will not change. It is suitable for DC brushed motors and cannot be connected to 220V household electricity.

Used for Childrens Toy Car

If the product is used in the modification of childrens car, the output end of the speed controller can be connected with a Forward and Reverse Switch to realize the function of forward and reverse control.

If there is a forward and reverse circuit regulator on the childrens car, please be sure to connect the speed controller in front of the forward and reverse circuit regulator (In other words: between the power supply and the forward and reverse circuit regulator) of the childrens car.

Otherwise, the speed controller may be damaged.
