Aluminium applications

– AC 800PEC unit controller ↔ AC 800PEC master controller communicates via PEC – PEC fibre optic link

(100 μs)

– Can be independent of the main controller control unit

– Allows emergency operation (full smooth current control in emergency mode without AC 800PEC,

only in combination with DCS800 pre-magnetisation)

– Predictive maintenance functions can be included

– Open circuit, overcurrent, undervoltage and overvoltage protection packages included in software

– Newly developed OPC (Open Circuit Protection) stand-alone PLC (Programmable Logic Controller)

that can be used in conjunction with AC 800PEC main controller functions or

as a stand-alone protection during main board maintenance

– Controlled shutdown in the event of an event without immediate tripping → reduced disruption to the

production process

– Potline load fluctuation detection and load shedding integrated into the application software

– Load tap converter fast tap function to prevent DC current overloads during disturbances

– Special Potline-to-Earth Resistance Measurement System (PERMS) based on the AC 800PEC series

– Maximum power regulation

– Prevents excessive power consumption and supports your generator

– Maximum DC voltage regulation to stabilise the process
