Featuring a wide input voltage range (1.8V-15V), a robust 2A continuous current capacity, and a fully adjustable PWM duty cycle (0%-100%), it ensures smooth and reliable motor control. Equipped with a self-resetting fuse and a bright LED power indicator, this controller combines safety and usability, making it an essential tool for DIY projects and professional applications alike.

## Description

Cautions: 1.Please connect this DC controller to DC power supply. Never connect directly to household 220V AC power supply, or it will be damaged; 2.Don't power supply larger than 12V, or it will be damaged; 3.This is a 2A high current governor, which can't drive larger than 0.5A continuous current / the 775 motor / children's car motor. Please confirm again before purchasing. Specifications: Input supply voltage:1.8V-15VDC The max output power:30W The max continuous output current :2A Duty Cycle adjustable: 0%-100% Package Included: 2x PWM Low Voltage DC Motor Speed Controller 2x Speed Control Knob

Review: Great little PWM module! - Awesome little module that handles SS well, great for controlling small fans/motors. There could be two minor improverments: 1) The led indicator is SMD, in a weird location next to the pot (looking down on the board). Great as an indicator when testing but useless if mounting in a case. If there was headers for an LED is would be better. 2) The terminals are pre-soldered to the board - again ideal for quick/ease, however when using the board in a case/perm fixture I would de-solder this in fav of soldering the connections directly to the board. You find lots of modules come with the header terminals but you have the option of soldering. Apart from that it works really well, extremely well for the price!
Review: Can use a 5v usb-A charger as a power supply for fans. - 5V usb supply into this module then a 12v fan yields great results. Controller and knob moves smoothly and mounts easily with included nut. With this simple setup, the fan is able to operate through a full range of RPM'. LED power indicator built into the PCB is nice and bright. It is easily visible when I poked a pin hole next to it and works nicely with a blob of semi-transparent sealer / glue to act as a diffuser. Good value items for your home project. Have since acquired more.

## Features

- ♥Widely Applications:It is suitable for the speed regulation of DC motor, fan, fish tank oxygen pump and other products in DC1.8V--12V.
- ♥PWM Motor Speed Controller:Ultra-low voltage dc motor governor; Potentiometer with switch function; Use a 2A resettable fuse to protect the controller; Power-on indicator.
- ♥High Performance:Input supply voltage DC 1.8V-15V. Maximum continuous output current 2A. Maximum output power 30W. Duty cycle adjustable 0%-100%.
- ♥Secure Enough:The governor is equipped with a self-recovery fuse. When the current is too large, the fuse is automatically disconnected. After cooling, the fuse is automatically restored.
- ♥Pay Attention:①Please connect this DC controller to DC power supply. Never connect directly to household 220V AC power supply, or it will be damaged; ②Don't power supply larger than 12V. ③This is a 2A high current governor, which can't drive larger than 0.5A continuous current / the 775 motor / children's car motor.
