RioRand 7-70V PWM DC Motor Speed Controller Switch 30A 2PCS

RioRand 7-70V PWM DC Motor Speed Controller Switch 30A 2PCS

Wide voltage 7-70V high current 30A design for a wide range of applications, on-board switch with run stop brake function, adjust the potentiometer soft line can be separated, wire length 15CM. Circuit for optimized design, duty cycle adjustment range is wide, adjust the motor smooth without bath sound No vibration, with power indication, the circuit design is stable and suitable for long time work. This product is a DC brush motor speed controller, need a separate DC power supply to the governor/controller power supply can not be connected to AC power can not drive brushless motor. Before wiring power, please read the wiring label, the input is DC power positive and negative poles can not be engaged, the output is connected to the motor (motor) does not need to be divided into positive and negative, if the direction of operation is not right, please replace the motor of the two wires. On the voltage or current regulation, adjust the duty cycle is in the unit time to control the on-off time, the output is a pulse, no-load with a voltmeter to measure the output voltage and input close to the motor connected to change the duty cycle added to the motor on both sides of the average voltage changes to achieve speed regulation, the voltage changes in the current of course followed by changes. The role of the current, and the current is derived from the change in voltage.
Brand:RioRand
Product Name :DC Brush Motor Speed Controller

DC Controller is required in the following situations:
1. Need a wider speed range.
2. Need fast dynamic response process.
3. Automatic smooth transition is required during acceleration and deceleration.
4. High torque is required when low speed operation is required.
5. Good excavator characteristics are needed, which can automatically limit the overload current to the set current
6.And it is a DC Motor Speed Controller,Not a Voltage Controller.

The DC speed regulator is mainly because the motor speed control and the step-down or voltage regulator have some of the same functions, but there are also some differences. They are not equivalent to the step-down or voltage regulator. The most direct and simple way to judge the quality of the speed regulator is Whether the speed can be adjusted normally when the motor is connected, if the voltage of the output terminal must be measured, please test after connecting the motor. This is accurate.
This is a 7-70V, 30A controller. If you want to operate it, you need to have a certain understanding of this controller. If you have any doubts, please consider purchasing carefully, or contact us, we will give technical assistance.
