Singlebutton threephase brushless motor driver with 100level acceleration/deceleration control and power memory function. It supports a potentiometer governor and 04.5V analog signals for stepless speed regulation. Key features and benefits Wide voltage range and compact design: 626V input with power in a small footprint, ideal when space is limited. Simple singlebutton operation: acceleration and deceleration controlled by a single button, with a potentiometer for precise speed tuning. 100level adjustable ramping: smooth, repeatable changes in speed to reduce mechanical stress and extend motor life. Power memory function: retains settings across power cycles for convenient reuse. Analog speed control: supports 04.5V signals for external or automated control when needed. No external control signals required: the drive begins operation as soon as power is applied, enabling quick setup and straightforward use. 3phase brushless controller: designed for threephase brushless motors, delivering reliable performance in demanding applications. What it is compatible with Threephase brushless motors used in compact or power applications. Systems that can utilize a potentiometerbased speed control or an analog 04.5V input for regulation. What it is suitable for Air pumps, water pumps, and oil pumps requiring smooth and controllable speed. Fans and other industrial control equipment that use threephase brushless motors. Performance and construction notes Wide voltage tolerance (626V) supports various power supplies. Smallvolume package combines power with a compact form factor. Stepless speed regulation via potentiometer provides precise control without steps. Operation is automatic upon power connection; external control signals are not required. Use scenarios HVAC or irrigation systems using air or water pumps where smooth ramping and quick startup are needed. Industrial cooling or ventilation setups requiring steady fan speeds and easy manual adjustment. Manufacturing lines with oil pumps or other threephase brushless devices that benefit from simple, reliable motor control with a singlebutton interface.
