Frequently Asked Questions
Q: What DC voltage range is this motor speed controller compatible with?
A: This wireless DC motor speed regulator supports an input voltage range of DC 12V to 30V, making it compatible with a wide variety of 12V and 24V DC motor systems commonly used in DIY projects, automation, and industrial applications.
Q: Can this controller handle both forward and reverse motor direction?
A: Yes. The wireless remote control allows you to switch the DC motor between forward and reverse directions with ease, and built-in limit switch support enables automatic stopping at preset positions.
Q: What is the maximum current and power this speed governor can handle?
A: The controller has a rated and maximum current of 30A. It supports up to 200W for 12V motors and up to 400W for 24V motors, making it suitable for moderate to heavy-duty DC motor control applications.
Q: Is this DC motor controller waterproof?
A: Yes. The unit features a waterproof design, protecting it from moisture and dust — ideal for outdoor installations, workshop environments, or any application where exposure to the elements is a concern.
Q: What PWM frequency does this speed regulator use, and why does it matter?
A: This controller uses a 21 kHz PWM (Pulse Width Modulation) frequency. A higher PWM frequency results in smoother motor operation, reduced audible noise, and lower heat generation compared to lower-frequency controllers.
