RioRand Premium PWM DC Motor Speed Controller 1803BK | 1.8V-15V (Recommended ≤12V) 2A with On/Off Switch for DIY Electronics
Product Description
RioRand Premium PWM DC Motor Speed Controller 1803BK | 1.8V-15V (Recommended ≤12V) 2A with On/Off Switch for DIY Electronics
- Ver.2.0 Premium Build: Features original 1803BK dedicated chip and high-grade components, delivering stable performance and extended service life for reliable long-term use.
- Precise PWM Speed Control: Operates on 1.8V-15V DC input (recommended ≤12V for optimal safety), with 0%-100% adjustable duty cycle to smoothly adjust small DC motor speed or dim low-voltage LEDs.
- Integrated Safety Protection: Built-in 2A self-recovery fuse and power-on LED indicator; the fuse automatically disconnects during overcurrent events and resets after cooling to safeguard your circuit.
- Compact & Practical Design: Mini 323214mm size (14g weight) with an integrated on/off switch, ideal for space-constrained DIY projects, small motor drives, and low-power electronic setups.
- Clear Usage Guidelines: Supports max 2A continuous current; not compatible with high-current motors (e.g., 775 motors, kids’ ride-on motors) or >0.5A continuous loads; for DC power only—never connect to 110V/220V AC.
DC Motor Speed Controller allows controlling the direction of a DC motor using a Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 0%-100%.
The motor speed controller is with a self-recovery fuse 2A and a Power-On LED light. It can easily provide a continuous current of 2A to your DC motor or other DC load.
Main technical parameters:
Input supply voltage: 1.8V-15VDC
The maximum output power: 30W
The maximum continuous output Current :2A
Duty Cycle adjustable: 0%-100%;
Specifications:
Item size: 32*32*15mm;
Package: 1 x motor speed controller ;
Operating instruction:
1. Connect your DC motor (or DC load) to the motor terminals as indicated on the wiring diagram.
2. Connect a voltage of 1.8V-15V 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 in line with the positive supply in order to protect the circuit from any possible short circuits.
3. You can now control the speed of the motor through potentiometer. Important Notes： An appropriately rated fuse (rated a little higher than the maximum current you expect to draw) is recommended to ensure safe operation. The controller is safe with a self-recovery fuse 2A. It will be damaged if connect the supply voltage with wrong polarity. Double check all connections before applying power and always turn off the power supply before making any wiring changes
