Overview
Line reactors for PM340 Power Modules, frame sizes FSA to FSE
Line reactor for PM340 Power Modules, frame size FSF
Line reactors limit the low-frequency harmonic effects and
reduce the load on the other loads in the same supply system.
In addition, the line reactors limit the current spikes at the
inverter input, e.g. in the case of commutation notches.
It is advisable to use the line reactors in combination with
unfiltered PM340 units and line voltages with a high harmonic
content (industrial networks).
■
Integration
The line reactors for PM340 Power Modules of frame sizes FSA
to FSE are designed as base components.
The line reactor is attached to the mounting surface and the
Power Module is mounted directly on the line reactor. The cables
to the Power Module are already connected at the line reactor.
The line reactor is connected to the line supply through terminals.
