Symmetrical Wiring Prepayment Electricity Meters LCD Display Digital Kwh Meter
The CA268-L is a typical South America oriented two phase three wire electric meter. It is equiped with 8 digits' LCD display and alternative IR optical communication port.It is built with superme electrical EMC parameters allowing it to be installed in very harsh environment. It is produced by ISO9001 standards and IEC metrological standards. It measures active and reactive energy by Class 1 accuracy and Class 0.5 is also availabe on request.
The meter is reserved for communication unit, such as PLC, RF, RS485, enabling it to communicate witha head-end server system. It can be utilized as an indispensable component of smart metering solution for automated meter readout, power limitation, remote load control, and advanced disconnection features.
FUNCTIONS AND FEATURES:
1) IEC standard compliant
2) Uni directional measurement of active and reactive energy
3) Preset power threshold, target usage on monthly basis
4) Load profiling record at programmable intervals
5) Multi-rate and holiday settings on Time of Use (TOU) basis
6) Self-diagnostic functionalities
7) Maximum demand measurement
8) Measure with neutral missing (optional)
