ZBT serial pulsing speed governing driver controller
The electric locomotive controller has basically experienced the three phrases of resistance cam speed governing, silicon controlled pulsing speed control and ZBT intelligent speed governing as the core technology of IGBT. The Corporation has developed ZBT intelligent speed control driver controller with independent intellectual property rights by actively absorbing the latest science and research achievement at home and abroad. The shortcomings such as high power consumption, fast mechanical wear, strong starting impact and huge repair expenditure for the original driver controller have been overcome. Therefore, Traction force and running speed of the electric locomotive has been greatly improved for protective function to be strengthened to ensure the electric locomotive’s safety, smoothness and reliability. The new generation of ZBT intelligent speed governing driver controller is the substitute for resistance speed governing driver controller and also the upgraded products of silicon control pulsing speed governing driver controller, which is regarded as the most advanced mine electric locomotive speed control driver controller currently at home. It is warmly welcomed for new and old customers to order the electric locomotive provided with a new generation of ZBT intelligent speed governing driver controller, or purchase a new generation of ZBT intelligent speed governing driver controller for transformation of your old electric locomotive.
