The EFU is the new generation of voltage and frequency converter designed to drive the WEBER MT IV motor in head internal vibrators. With a low weight and no moving wear parts the EFU offers an electronic system that protects the operator against short-circuits, ground faults and current leakage (fault-current principle). It also protects the converter from overloading and overheating.
Several internal vibrators can be connected, depening on the type. Consumers with 48 and 250 V can be connected simultaneously to the EFU with converter.
