The frequency converter of this modification is designed for electric drives with “the fan” mechanical characteristic: fans, centrifugal pumps, blowers, compressors, centrifuges, etc. This frequency converter is also applicable for machines, load torque which can be constant and equal to the rated motor torque in the speed range from zero to nominal.
The transmitter for general industrial and crane performance can be equipped with a regenerative braking energy into the network, which is being built with the input of the active rectifier, providing recovery of the flow of energy from the load to the mains supply. At the same time the drive is carried out in the four quadrants of the mechanical characteristics, which provides high dynamic performance drive and energy savings due to energy recovery in the mains supply to the generator mode of the engine.
