The CA268-L is built for 2 phase 3 wire alternative current network, featured for its low cost and high effeciency performance with availability for expanded smart metering functionalities. It is designed to sustain in under-voltage as -50% Vn and 30Vm of RF immunity withstand, to be installed in very harsh environments for light commercial and industrial applications. The meter measures active energy and reactive engery (optional) in both directions. It is produced in accordance withISO 9001 and IEC IEC62053-21 and IEC62052-11 standards and offers Class 1.0s accuracy.
