Frequently Asked Questions
Q: What types of pumps is this motor speed controller compatible with?
A: This speed regulator drive board is specifically designed for three-wire 12V and 24V DC diaphragm pumps and vacuum pumps. It is ideal for applications requiring knob-based, stepless speed control via a terminal connection interface.
Q: How do I connect the motor speed controller to my pump?
A: The drive board uses a terminal block connection interface. Simply wire your three-wire diaphragm or vacuum pump leads into the corresponding terminals on the board, connect your 12V or 24V DC power supply, and use the rotary knob to adjust motor output speed as needed.
Q: Can this speed controller be used outdoors or in humid environments?
A: Yes. The controller is rated for ambient temperatures between -25°C and 65°C (non-icing) and operates in humidity levels of 35–95% (non-condensing), making it suitable for a range of indoor and sheltered outdoor applications.
