Singlebutton operation supports 100level speed switching for easy selection of speeds, with smooth acceleration and deceleration, belt power memory function, potentiometer governor mode, compatibility with 04.5V analog signals, and stepless speed regulation. This drive uses a threephase brushless Hallfree control board and is designed to operate reliably. BLDC controller with a wide input voltage range of 626V, compact and power design, featuring a singlebutton potentiometer option. Electrical regulation is specifically suitable for air pumps, water pumps, oil pumps, fans, and other industrial control tools that use threephase brushless motors in their development and designs. Practical applications and scenarios: Use with air pumps, water pumps, or oil pumps in cooling, irrigation, or fluid transfer systems requiring adjustable speed control. Control fans or other industrial cooling or ventilation equipment in manufacturing or processing environments. Ideal for small automation projects or robotics that utilize threephase brushless motors and require compact, reliable speed control.
