PWM DC Brushed Motor Speed Controller Switch with LED Display

Key Features

• Input Voltage Range: 10V to 55V DC
• Maximum Continuous Current: 60A
• Control Method: Pulse Width Modulation (PWM)
• PWM Frequency: 15 kHz
• Adjustable Duty Cycle: 0% to 100%
• Display: Digital LED screen shows output percentage
• Control Functions: Three-position switch for forward, reverse, and stop
• Input Interface: Rotary potentiometer knob for speed adjustment

Replaces / Cross-Reference Part Numbers

• This is a universal component for custom applications or repairs.
• Can replace existing PWM controllers with matching electrical specifications (10-55V, up to 60A) for brushed DC motors.
• Always verify voltage, current, and physical dimensions before replacing an existing controller.

Compatibility & Fitment

• Designed for use with two-wire brushed DC motors.
• Compatible with 12V, 24V, 36V, and 48V DC power systems.
• Suitable for applications such as:
  • Motorized ride-on toys
  • Small electric vehicles and scooters
  • Conveyor belt systems
  • Pump and fan speed regulation
  • Automation and robotics projects

When to Replace

• Motor fails to operate or responds intermittently.
• Inability to adjust motor speed; motor operates only at full speed.
• No output reading or erroneous data on the LED display.
• Overheating of the controller unit under normal load conditions.
• Visible damage, such as burn marks or broken components, on the circuit board.

Installation Tips

• Disconnect the power supply before wiring or making adjustments.
• Verify correct polarity for power input and motor output terminals.
• Ensure the controller is mounted in a location with adequate ventilation to prevent overheating.
• Use a wire gauge sufficient to handle the rated 60A current to avoid damage or performance loss.
• Do not exceed the specified maximum input voltage of 55V DC.
