Equipped with multi-channel digital and analog I/O terminals,expansion slot for communication adapters such as Data Highway Plus. Integrated dynamic braking transistor,LED status display and keypad interface. Widely used in fans,water pumps,conveyors,packaging lines and heavy-duty process automation equipment.

Working principle

Three-phase AC mains power is rectified to DC bus. IGBT power stage outputs adjustable voltage and frequency AC to regulate induction motor speed and torque. Accepts analog,digital or network command signals. Closed-loop vector mode enables high starting torque and accurate speed regulation. Dynamic braking circuit consumes regenerative energy during motor deceleration.
