A mains choke is an inductive resistor which can be connected between the mains supply and the frequency inverter.
Less effects on the mains: the wave form of the mains supply is a closer approximation of a sine wave.
Reduced mains current : reduction of the r.m.s. current (lower costs).
Increased service life of the 8200 vector: The service life of electrolytic capacitors in the DC bus can be increased considerably by reducing the AC load.
Can be used with frequency inverter 0,37kW at Rated power 400VAC
