Frequently Asked Questions
Q: What voltage range does this PWM motor speed controller support?
A: The PFULTR PWM Speed Controller supports a wide DC input range of 6V to 60V, making it compatible with a broad variety of motors and power supplies commonly used in DIY, automation, and industrial projects.
Q: How does the encoder knob control work on this speed controller?
A: The rotary encoder knob allows you to make smooth, precise incremental adjustments to your motor's speed. Unlike a simple potentiometer, the encoder provides consistent, repeatable positioning and does not drift over time — ideal for applications requiring accurate speed settings.
Q: What is the difference between Option A and Option B?
A: The two variants (A and B) offer different configuration options to suit varying project requirements. Please refer to the product variant selector and any included documentation to choose the configuration that best matches your motor and wiring setup.
Q: What are the physical dimensions of this controller?
A: The controller measures 96 × 61 × 34 mm (approximately 3.77 × 2.4 × 1.33 inches), making it compact enough for integration into most project enclosures while still offering clear, accessible knob control.
