Description
The series covers power up to 4000 kVA, and the datasheets list EMS 2101 up to 272 kVA and EMS 2102 up to 544 kVA. The connection scheme is matched to the network, either 1 or 3 phases, 1×3P or 3×1P. The wide ±40 % range is combined with 0,5 % accuracy, and each phase is regulated independently. A class II SPD and parameter measurement come as standard, so no separate module is needed to watch input and output voltage. A protection rating of IP20 for indoor use or IP54 for outdoor use decides whether a separate room is needed.
How to choose
Power, connection scheme and installation place decide the choice. IP20 suits an indoor room and IP54 suits outdoor use. Small power of 44–100 kVA is covered by Light Industrial (EMS 2100) with a range from ±30 % to ±15 %, while the EMS series is needed when ±40 % and higher power are required. For housing the stabiliser in a container there is Containerised AVR/VO in 20 or 40 ft.
