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 [citation:1][citation:2]. It provides smooth 0100% duty cycle adjustment via a built-in potentiometer with an on/off switch [citation:1][citation:4][citation:5].

Wide Voltage Compatibility - Supports 1.8V to 15V DC input [citation:1][citation:2]
Integrated Protection 2A selfrecovery fuse for overcurrent safety [citation:1][citation:4][citation:6]
Input supply range is 1.8V to 15V DC with maximum 2A continuous output [citation:1][citation:2][citation:6]
Use a multimeter to verify polarity before connecting power [citation:1][citation:4]
Never connect to household 220V AC power [citation:1][citation:2][citation:4]

Connection Guide

Terminals are clearly marked [citation:8][citation:11]:

  • Motor + and -: Connect to DC motor
  • Power + and : Connect to DC power source (1.8V15V)
Motor speed is controlled by turning the potentiometer [citation:3][citation:6]
To change motor direction, swap the motor wires [citation:3][citation:11]
Observe correct polarity to avoid damage [citation:1][citation:4]
Do not exceed 2A continuous current rating [citation:1][citation:4]

Important Limitations

The controller is rated for 2A maximum continuous current [citation:1][citation:2]. It is not suitable for large motors like 775 motors or motors drawing more than 0.5A continuous current [citation:1][citation:2][citation:4]. Using it with 12V lead-acid batteries may cause damage [citation:1][citation:4].

SelfProtecting Design Built-in 2A resettable fuse [citation:1][citation:6]

Clear Wiring - Labeled terminals prevent errors [citation:8]

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