EEI MASTER M750 (8YS750Q00AF2)
Application
The EEI power converters are used to:
• Solar power plants
• Hybrid power plants
• power quality (eg voltage regulation)
• peak shaving
• load levelling
•off grid power supply(UPS)
• management of power unbalance
Inverter
Inverter enclosure made of steel panels.
Front opening through lockable doors
to ease access to all parts. Side and rear
access through bolted panels.Inverter drive specifications:
•IGBT power circuit, film capacitors andlow inductance connections
• Digital management of controlparameters, alarm diagnostics,
analogue and digital I/O signals fromdedicated microcontroller and DSP
software
• 400V three-phase and neutral AC output
Reliable and safe
Inverters are manufactured followingsystematic and rigorous production andtesting processes. All products developed by EEI are ISO 9001 certified.
Power surge protections from both grid andbattery side are installed to preventdamages on the inverter drive.
