Chokes for the Rail Industry
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.
Rated current: 10 - 2000 Rated inductance: 0,04 - 80 Rated voltage: 25 AC / 750 - 3600 DC
The REO air choke in toroidal design has a very low magnetic leakage and is very well suited for applications that requirelow EMC limits. The complete unit of inductor, cooled air flow, suspension and connections is designed for use with railed vehicles.
Manufactured to customer specification.
Rated current: 10 - 1000 Rated inductance: 0,01 - 1,2 Rated voltage: 25kV AC / 750 - 3600 kV DC
Completely encapsulated chokes, with water pockets, these are connected to a liquid-cooling system. Constructed within the windings and encapsulating compounds. This technology combines the advantages of encapsulation technology to achieve a high ingress protection ratings and effective heat dissipation at its source.
Rated current: 100 - 3000 A Rated inductance: 5 - 200mH
The iron choke 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. A REO ED Choke provides particularly high inductivity and low magnetic leakage.
Manufactured accoding to customer specification.
Rated current: 30 - 2500 Rated inductance: 0,1 - 280 Rated voltage: 5 kV AC / 3600 kV DC
