The IGBT controller also named as DC Chopper Speed Control for locomotive it got 2 type the normal type and the explosion-proof type the explosion-proof type is usually applied in the place with great moist or the place with explosion gas.
The IGBT Controller has a simple circuit no runaway phenomenon and rarely replaces contacts which greatly reduces the maintenance workload. Using this device the locomotive starts smoothly the speed is uniform the overload capacity is strong the electric energy is saved by about 30% and the service life of the battery is prolonged. It is deeply welcomed by drivers maintenance personnel and grassroots management personnel.
