RioRand DC 3V 6V 12V 24V 35V 5A Motor Speed Controller PWM Speed Control Ultra Small LED Dimmer（2PCS）

Description

h2>Product Overview

The RioRand DC 3V-35V 5A Motor Speed Controller is a compact, ultra-small PWM dimmer designed for precise speed control of DC brush motors and LED lighting systems. With a working voltage range of 3V to 35V and a maximum control power of 90W, this controller delivers a continuous 5A current. It features an adjustable duty cycle from 1% to 100% at a 10kHz PWM frequency, making it ideal for applications requiring fine-tuned speed regulation. The controller includes a self-recovery fuse that automatically disconnects if the current exceeds safe limits and resets once cooled, ensuring long-term reliability. Its low quiescent current of 0.015A in standby mode conserves energy. The device is lightweight (1.06 oz) and measures 4.72 x 3.15 x 1.18 inches, making it suitable for integration into small-scale projects or portable devices.

Usage

This controller is ideal for hobbyists, makers, and small-scale industrial users who need to control the speed of DC motors or dim LED lights. It is commonly used in RC vehicles, small fans, pumps, robotics, and DIY electronics projects. The compact size and low voltage compatibility make it suitable for battery-powered applications, including portable devices and educational kits. Its PWM functionality allows for smooth speed transitions, reducing mechanical wear and improving efficiency. The self-recovery fuse adds safety for users who may not have access to external circuit protection.
