Vivid™ 4 Power Distribution
5-7-1
Electrical Power
The Vivid™ 4 system can be set up to operate from the following 50/60 Hz AC voltages: 100V, 120V,
220V, 230V and 240V.
The local input voltage is converted to an internal voltage of 230V, via the Trafo. This voltage is
distributed to different system components and converted into DC voltages in the BEP and the Front
End, to support their operation.
