• Measuring all major factors required for power &
energy management • Transducer combined with
3 displays in one enclosure • RS-485 or DC current
output • Totalized counter values stored in non-vola-
tile memory • Occupying less panel space, requir-
ing fewer connection• Easily replacing standard 110
mm (4 /16 in.) square size, long scale meter • Pa-
rameters are field-selectable
