Product Description

1803BK PWM Low Voltage DC Motor Speed Controller

= 2A Adjustable Driver Module for Small DC Motors =

The 1803BK is a compact PWM speed regulator designed for lowvoltage DC motors operating from 1.8V to 15V . It provides smooth 0100% duty cycle adjustment via a built-in potentiometer with an on/off switch .

Wide Voltage Compatibility - Supports 1.8V to 15V DC input
Integrated Protection 2A selfrecovery fuse for overcurrent safety
Input supply range is 1.8V to 15V DC with maximum 2A continuous output
Use a multimeter to verify polarity before connecting power
Never connect to household 220V AC power

  1. Small DC motor speed control
  2. Fan speed regulation
  3. Aquarium pump control
  4. DIY electronics projects
  5. LED dimming applications
Safe and Reliable Selfresetting fuse protects against overloads
Simple Installation - Clearly marked terminals for easy wiring

√ Includes screw terminals for secure connections

√ Potentiometer with on/off switch function

√ Compact design for space-constrained projects

= Connection Guide =

Terminals are clearly marked :

  • Motor + and -: Connect to DC motor
  • Power + and : Connect to DC power source (1.8V15V)
Motor speed is controlled by turning the potentiometer
To change motor direction, swap the motor wires
Observe correct polarity to avoid damage
Do not exceed 2A continuous current rating

= Important Limitations =

The controller is rated for 2A maximum continuous current . It is not suitable for large motors like 775 motors or motors drawing more than 0.5A continuous current . Using it with 12V lead-acid batteries may cause damage .

SelfProtecting Design Built-in 2A resettable fuse

Clear Wiring - Labeled terminals prevent errors

√ Ideal for small DC motors, fans, and LED applications

√ Low-cost PWM solution for hobby and DIY projects
