Digital Control Systems for Rail Traction Engines
HEINZMANN control systems for rail traction engines are characterised by high precision and long-term stability. For every application project, they provide specific control, protection and monitoring functionality. The compact, robustly designed hardware components are tailored to suit the harsh environments of the power car. For diesel-electric drives, both speed and load control for the on-board generator (AD and DC) are combined – ensuring maximum traction efficiency with variable excitation control. Systems operate in installations worldwide, chosen by leading locomotive manufacturers for retrofitting of diesel-electric and diesel-hydraulic locomotives.
