Dambach Lagersysteme: Smart Energy management (DSE)

DSE, the DAMBACH Smart Energy Management system for rail-guided stacker cranes, considerably improves the economics of an automated warehousing system. Rail-guided stacker cranes are therefore much more efficient – and achieve that without a loss in performance.

• Peak currents from the mains reduced by a factor of five
• Smaller mains supply points and energy infrastructure
• Reduced energy consumption without complicated feeding into the mains
• No idle power compensation system
• Automatic compensation for mains fluctuations
• Can also be retrofitted to some existing controls

Efficiency:

well-conceived energy management
By using the existing mains supply, railguided stacker cranes can increase their performance. The additional energy needed for improved performance is gained from the power caps. The power caps are charged by recovering energy from the rail-guided stacker cranes as they lower their loads and/or brake. A smaller mains supply is possible with new systems.

Benefits:
