CCM5D PWM DC Motor Speed Controller 6V–30V LED Display

CCM5D PWM DC Motor Speed Controller — Precision Variable Speed Regulation

Take full command of your DC motor's speed with the CCM5D PWM DC Motor Speed Controller. Featuring a bright 0.56-inch 3-digit LED display and a smooth 0–100% adjustable duty cycle, this compact module delivers reliable, accurate speed regulation for a wide range of DC motor applications — from hobby electronics and robotics to industrial automation and DIY builds.

Key Features

• Wide Voltage Range: Compatible with 6V, 12V, 24V, and up to 30VDC input supplies — versatile enough for most DC motor setups.
• Bright LED Display: Large 0.56-inch 3-digit LED readout shows the PWM duty cycle (000–100) clearly, even in low-light or high-glare environments.
• Full-Range Speed Adjustment: Continuously adjustable from 0% to 100% duty cycle via a precision potentiometer — smooth, stepless control at your fingertips.
• High Output Power: Handles up to 240W maximum output power, with a continuous output current of 5A and a peak (summit) current of 8A.
• 16kHz PWM Frequency: High-frequency switching minimizes motor noise and heat for efficient, quiet operation.
• Built-In Push-Button Switch: Integrated push key lets you toggle the controller ON/OFF independently of the power supply — convenient for quick motor starts and stops.
• Compact & Lightweight: Measures just 79 × 42 × 25 mm and weighs approximately 58g — easy to mount in tight spaces.

Specifications

Wiring & Operating Instructions

1. Ensure power is completely OFF before wiring the controller.
2. Connect the input power wires to the controller's supply terminals (observe correct polarity — do not reverse positive and negative).
3. Connect your DC motor or DC load to the output terminals.
4. Turn on the power supply and adjust the potentiometer to set the desired speed (duty cycle).
5. The LED display shows the current PWM output duty cycle in real time.
6. Use the push-button to toggle the controller ON or OFF as needed.

⚠️ Safety Warnings

• Do NOT reverse the positive and negative power connections — incorrect polarity will damage the controller.
• Do NOT exceed the rated current or voltage limits.
• Ensure adequate ventilation around the controller during high-load operation.

Frequently Asked Questions

Q: What voltage range is the CCM5D PWM motor speed controller compatible with?

A: The CCM5D is compatible with DC input voltages ranging from 6V to 30V, making it suitable for common supply voltages like 6V, 12V, and 24V systems. Always ensure your power source falls within this range to avoid damage.

Q: What types of motors or loads can I use with this PWM speed controller?

A: This controller is designed for DC motors and DC loads with a continuous current draw of up to 5A (peak 8A) and a maximum power of 240W. It is ideal for brushed DC motors used in fans, pumps, conveyor systems, robotics, and DIY electronics projects.

Q: How does the LED display work on the CCM5D?

A: The 3-digit LED display shows the current PWM output duty cycle as a percentage from 000 to 100. For example, a reading of "066" means the motor is receiving 66% of the supply voltage's power, giving you a clear, real-time readout of the motor's speed setting.

Q: Is the CCM5D PWM controller safe to use for beginners?

A: Yes — as long as basic electrical safety practices are followed. Always wire the controller with power OFF, respect polarity, and do not exceed the rated current and voltage. The built-in push-button ON/OFF switch adds a convenient layer of control. Refer to the included wiring diagram for correct installation.
