NettetThe drive operates with a high degree of stability – even during line supply fluctuations; Improved EMC and grid (harmonics) performance due to integral DC choke (FSA-FSG, up to 400 hp / 250 kW) SINAMICS G120X's operating temperature extends from -4°F to 140°F (-20°C to 60°C )(depending on the exact version). Nettet15. nov. 2024 · Like an AC line reactor, a DC bus choke limits the peak value of the line (supply) current, which mitigates harmonics transmitted from the line — especially the 5 th and 7 th harmonics. This is important because the 5 th and 7 th harmonics are the main contributors to total current harmonic distortion, and DC bus chokes do a better job of …

NettetSmaller kW drives can be particularly susceptible to supply variations and also to connection to supplies with low impedance / high short circuit current and line chokes are recommended in these cases. Notes: Fitting an Input line reactor will cause a drop in the incoming supply voltage level to the AC drive (generally between 2 and 5%). NettetOverview. A mains line reactor (choke) is required for application architectures with more than 16 A mains current. Up to 16 A, a mains line reactor is necessary to reduce the harmonics of the mains current. The rated power of the drives is limited. Without mains line reactors, the rated power of the drive is further reduced (refer also to the ...
