LOBO CONTROLLER CONCEPT
The “LOBO” Controller is a compact Solid State DC Traction Motor Controller custom designed for use in underground mining and tunnelling locomotive applications. The controller design makes use of the latest microprocessor technology to control the main power semiconductor.
The controller comprises of a programmable control computer (Logic), the IGBT Power Semiconductor Module, drivers control and LCD display/driver interface. The modular design offers maximum safety and improved maintainability. User interface can be adapted for a specific application which includes diagnostic codes for ease of fault finding.
