Air Choke Type NTT LD
The air choke is designed for use in vehicles in direct current (DC) voltage systems. This includes railed vehicles such as underground and commuter trains, but also trolleybuses. The term “air choke” refers to the complete, ready-for operation unit comprising the inductor, cooled air flow, suspension and connections. The air choke is an inductive component which stores magnetic energy. It filters voltage peaks and prevents voltage dips so that deviations from the ideal converter input are kept as low as possible. Furthermore, it also reduces the circuit disturbances, which are created as a result of parasitic circuit components and switching operations. These products are manufactured according to customer specification.
