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

From the shop's description

DC Motor Speed Controller Board Module (PWM, 48V 20A) with POT is a high-quality electronic component designed for Arduino, prototyping, and educational electronics. 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 Features: Input voltage: DC 6–48V Current rating: 20A PWM-based speed control Includes POT (Potentiometer) for manual adjustment High efficiency & low heat design Ideal for DC motors in e-bikes, robots, fans, pumps Smooth speed transition without noise Easy to wire and integrate
