DC Motor Speed Controller Board Module (PWM, 48V 20A)

From the shop's description

Description: This High Power DC Motor Speed Controller lets you control the speed of a DC motor using a Pulse Width-Modulated (PWM) DC voltage. It can be used to drive all DC Brushed Motors that work between 10V-48V DC and consume up to 20A of current. Product Features Regulating the DC motor speed with a wide range through pulse-width-modulation Incorporating high power dc motor driver module Input voltage range from DC 10V to 60V, and output current 20A maximum (no more than 10amp, 450 watt if longtime working, and make sure the heat dissipation works well) Packed in an antistatic bag to protect it from static damage during transportation Well made and durable Specifications: Input supply voltage:10V-48VDC The maximum continuous output current: 20A Operating instruction: Connect your DC motor (or DC load) to the motor terminals. Connect a voltage of 10V-48V DC to the circuit making sure of the correct polarity of the connection. Note that the voltage applied to the motor will be supply voltage applied to the circuit. It is recommended to add an appropriately rated fuse inline with a positive supply in order to protect the circuit from any possible short circuits. You can now control the speed of the motor through a potentiometer. Applications: For Speed Control Of all Types of DC Brush Motors For Controlling Automotive Cooling Fan Speed, Auto Fan Speed, Windshield Wipers, Auto Air Conditioning. For Controlling Belt Speed, Pipeline Exhaust Fan Speed, Treadmill Speed, Multi-Speed Parallel Computer Fan, Electronic Fan Speed. Package includes: 1 x DC Motor Speed Controller Board Module (PWM, 48V 20A)
