CA168-D01
Single Phase Keypad Electricity Meter
The CA168-D01 is a multi-function single-phase smart meter with embedded communication. The meter is used to measure electrical energy accurately for commercial and residential customers. The CA168-D01 can be applied to payment (STS compliant). The communication with an optional external keypad (customer interface unit CIU) can be done via power-line communication(PLC), radio frequency(RF) or by cable connection.
