EG2T-40/400-EMC Variable Frequency Drive Unit

Module Feature

EG2T-40/400-EMC belongs to EG2T heavy-duty variable frequency drive series. It adopts high-performance IGBT power module, supporting V/F control and sensorless vector control. Built-in EMC filter suppresses electromagnetic interference on industrial site. Integrated braking interface connects external braking resistor to consume regenerative energy during rapid deceleration. Digital control board reserves multiple analog and digital I/O terminals, standard Modbus RTU communication interface for PLC and industrial network connection. Equipped with built-in cooling fan and metal housing, suitable for continuous heavy-load operation. Widely applied in water pumps, industrial fans, material conveyors and other heavy-duty motor speed control scenarios.

Working principle

Three-phase AC input power passes through rectifier bridge and converts to DC voltage. IGBT inverter converts DC into adjustable frequency and voltage AC power to drive the motor. The motor speed changes with output frequency adjustment. When the motor decelerates, regenerative energy returns to DC bus; external braking resistor consumes excess energy to avoid overvoltage trip.
