Use and scope of application

NMAKSG (also available with model NMACL as input and NMOCL as output) series of dry iron core series reactors are used for inverter input and output side terminals, connected in series with the inverter. When there are a large number of harmonic sources such as rectification and converter devices in the low-voltage network. At the time, the high harmonics generated by it will seriously endanger the safe operation of the main transformer and other electrical equipment. When the reactor is connected to the inverter, it can effectively absorb the harmonics of the power grid, reduce the leakage current caused by the input high harmonics, reduce the noise and eddy current loss of the motor, smooth filter, reduce the transient voltage dv/dt, and extend the motor. life.
