Designed for regulating threephase brushless motor driven devices such as air pumps, water pumps, oil pumps, fans and other industrial control electric tools that use threephase brushless motor development and designs. Key features and benefits Singlebutton model Supports 100level acceleration and deceleration switching Belt power memory function Potentiometer governor model Supports 04.5V analog signals Stepless speed regulation BLDC controller Wide input voltage range 626V power, compact size Small volume with singlebutton potentiometer control Threephase brushless controller design Easy operation and compatibility Drives operate when power is applied and do not require external control signals Potentiometer stepless speed regulation Buttontype operation enables acceleration and deceleration with a single button Specific use scenarios Industrial process line Use to regulate pump speed (air, water or oil) to match production requirements, improving process control and energy efficiency. Cooling or ventilation systems Adjust fan speed via potentiometer for varying thermal loads, maintaining stable temperatures with minimal energy use. Lubrication and fluid handling Control pump flow in lubrication or oil transfer applications, providing smooth, adjustable performance without external signaling. Technical highlights Supports a wide range of threephase brushless motors through a compact, power controller Voltage tolerance from 6V to 26V enables flexible integration with different power supplies Singlebutton operation plus potentiometerbased, stepless speed control for straightforward, reliable control No external control signals required for basic operation, simplifying installation and reducing wiring complexity Please note: This description preserves the original product's brand scope, specifications, models, and functions without introducing features or omitting details from the provided text.
