Card Prepayment Wireless Electricity Meter , 6 Digits Single Phase Kwh Meter
The PLC-G3 communication is added to the CA168-C, enabling it to be connected to an AMR/ AMM/AMI back end server for smart metering features such as real-time data readout, load management, remote tariff setting, load control by disconnection / reconnection,etc. The meter is a single phase two wires 60 Amp per phase card type prepayment electric meter that combines STS standards with 3DES security encryption technology. The meter is manufactured by IEC 62052-11, IEC62053-21 metrology criteria and ISO9001 standards, an integration of high precision technology and high quality standard. It supports flexible tariff plans on TOU (Time of Use) basis.
The meter is built with 13kV / 6.5kA Varistor providing surge protection agaisnt lightening and other line surges. Switch mode power supply (SMPS) option is also available ,allowing the meter to work with voltage down to 80V , good for African continent where brownouts and voltage dip is very frequent.
Features
a) STS standard encryption
b) PLC G3 communication up to 200 meters between the MCU and CIU
c) Disconnects on power threshold breach and no credit
d) Power limit and low power warning programmable
e) Measure reverse energy as positive ( SRE )
f) Anti-tamper function
g) Multi-rate and multi billing cycles
h) IEC 62056-21 and DLMS/COSEM compliant
i) Automatic meter readout remote upgrade (optional)
Utility benefits
1) Interoperable with STS prepayment system
2) Easy to install and retrofit due to BS footprint mounting
3) Meter provides various information as A, V, PF, usage freeze on daily monthly basis
4) Reduce operational and inventory costs
5) Hardware and software security protection
6) Long life time of 15 years
