Single-phase and three-phase line chokes from TRAMAG
For the protection of the inverter input
Line chokes protect the inverter input. Mains perturbations caused by commutations are limited. They reduce the TDHi to a typical value between 35 % and 45 %, depending on the size of the coil.
We provide line chokes for the following industries

Technical characteristics and quality features
Line chokes: Applications
Line chokes and commutating chokes are used on the line side of the rectifier/frequency converter. They are installed before the (AC drive) converter.
Our chokes reduce the proportion of low-frequency harmonics in the network and thus improve network performance.

- Current up to 10,000 A
- Short circuit voltage typ. 2% or 4%
- Mains voltage up to 1,000 V
- Frequency typ. 50-60 Hz
Line chokes: Quality characteristics
- DIN EN 61558-2-20
