Overview
Line reactor for PM240-2 Power Modules, frame size FSA
Line reactor for PM240 Power Modules, frame size FSGX
Line reactors smooth the current drawn by the inverter and thus
reduce harmonic components in the line current. Through the re-
duction of the current harmonics, the thermal load on the power
components in the rectifier and in the DC-link capacitors is re-
duced as well as the harmonic effects on the supply. The use of
a line reactor increases the service life of the inverter.
■
Integration
A DC link reactor is integrated in the PM240-2 Power Modules
FSD to FSF and therefore no line reactor is required.
