The 1203B PWM DC Motor Speed Regulator is a compact, highly efficient motor driver module designed to control the speed of brushed DC motors, fans, or LED brightness using Pulse-Width Modulation (PWM). It regulates speed seamlessly by altering the duty cycle from 0% to 100% without losing motor torque.

Core Technical Specifications
  • Input Voltage Range: DC 6V to 28V
  • Maximum Continuous Current: 3A
  • Maximum Output Power: 80W
  • PWM Frequency: 21 kHz
  • Duty Cycle Adjustable Range: 0% to 100%
  • On-Board Control: Built-in rotary potentiometer knob.
  • Safety Protection: Built-in self-recovery fuse for overcurrent faults.
Standard Pinout Configuration
The module features a 4-screw terminal block:
  • Power + (V+): Connect to the Positive terminal of your DC power supply.
  • Power - (Gnd): Connect to the Negative terminal of your DC power supply.
  • Motor + (M+): Connect to the Positive terminal of your brushed DC motor.
  • Motor - (M-): Connect to the Negative terminal of your brushed DC motor.
Critical Operating Rules
  • No Reverse Polarity: Reversing the positive and negative power inputs will destroy the controller.
  • DC Brushed Motors Only: This regulator cannot be used with AC power supplies or brushless motors.
  • Testing Requires a Load: You must connect a functional DC motor to accurately test the speed control. A multimeter alone will not show voltage changes.
