Power converters to stabilize machines in opencast mining

 

Durable drive systems and efficient onboard power supply for harsh conditions

PowerTech converters are equipped in various kinds of machines like dredgers, cranes, heavy duty in opencast mining where the electronics are exposed to the highest loads, like sudden temperature changes, vibration, humidity and splash water, sulfur or even mechanical shock. The required on board supply of such machines has a bridge range – started from low voltage up to several hundred kilowatts or even several megawatts. The PowerTech converters can be used for the electric propulsion systems, also to provide the necessary auxiliary power supplies and for various operating on board (from drive to air conditioning). Using the technology of PowerTech elaborate protective structures for electronics can be saved. Due to the flexible design of the PowerTech converters also many other applications are possible like in civil engineering, tunnel drilling, oil and gas subsidies or generally in the chemical industry.
