IEC Standard 2 Phase Electric Meter , Three Wire Prepayment Electricity Meters
The CA268-L is a powerful 2 phase 3 wire electricity meter for residential and light commercial industrial environments. The meter comines high precision metering metrology and data management technologies, allowing for automated meter reading and interval usage and power quality data retention. Using open protocols such as DLMS/ COSEM enables it to interface with other sensors or head-end systems.
It is built with surge protection arrestor sustaining up to 13kV lightening and with 30Vm RF immunity withstand performance, allowing it to be installed in severe environments.The meter allows flexible setting for usage target alarms on monthly basis, aiming to remind the consumers of budgeting their consumption.
FUNCTIONS AND FEATURES:
a) Class 1.0 as per IEC standards
b) Multi-tariff plans and holiday settings on Time of Use (TOU) basis
c) Available for communication unit upgrade for AMR AMI smart metering features
d) DLMS / COSEM open protocol
e) Optical port and RS485 for alternative meter readout
f) Uni-directonal measurement
g) Large character LCD , auto-scrolling display supports display during power outage
User Benefit
