Designed for use with threephase brushless motors, this controller is ideal for air pumps, water pumps, oil pumps, fans, and other industrial control electric tools. It combines compact size with power and versatile control options. Key benefits and features Broad compatibility with threephase brushless motors: suitable for air, water, and oil pumps, fans, and various industrial control tools. Simple, poweronly operation: the driver runs when power is supplied and does not require external control signals. Potentiometer stepless speed regulation: continuous speed adjustment via a potentiometer for smooth performance. Singlebutton model options: 100level acceleration and deceleration with a single button Belt power memory function Potentiometer governor mode 04.5V analog signals for stepless speed regulation Wide voltage range and compact design: BLDC controller supports 626V input with power in a small form factor. Threephase brushless controller: robust, efficient control suited to demanding industrial applications. Specifications and attributes to note Motor compatibility: threephase brushless motors Voltage range: 626V Control interfaces: potentiometer for stepless speed control; optional 04.5V analog input Modes: singlebutton model with 100level acceleration/deceleration, belt power memory function, potentiometer governor mode Form factor: powerful yet small in size, suitable for compact installations Why you need this product Eliminates the need for external control signals, simplifying installation Provides precise, repeatable speed control for pumps and fans, protecting mechanical components through smooth ramping Offers flexible control options (manual potentiometer, singlebutton operation, and analog input) to fit different integration scenarios Delivers strong performance in a compact package, suitable for spaceconstrained applications Practical use scenarios Pump systems in industrial processes: use the potentiometer for finetuned flow and pressure control without complex wiring. Cooling or ventilation fans: ramp up and down quickly and smoothly to meet changing thermal demands while keeping noise and wear to a minimum. Automated equipment and conveyors: integrate the 04.5V analog input with existing controllers or PLCs to achieve precise speed profiles and synchronization.
