Nettet2. jun. 2024 · If specified, DC choke will be built in to the drive and for large drives there will be slots available to install DC choke if customer decides to install it in future. Below is a brief description of the advantages of DC link choke. 1) Reducing line side harmonics: DC choke behave similarly to AC line reactors from a harmonic mitigating ... 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).

NettetTo evaluate the influence of an additional AC line reactor on a drive already equipped with a DC choke, the maximum input lines voltage unbalance of 2.1% is kept constant. The additional AC line reactor value is increased from 0 to the same value already used to compare the DC choke and AC line reactor in the previous section. NettetAdvantages of using a DC link choke.
