Low Voltage 3 Phase Electric Meter / Backlit LCD Surge Safe Sts Keypad Meter
The CA368 is a standalone solid state three phase four wire / three wire (optional) keypad based electric meter. It adopts STS standard encryption for prepayment applications. The meter supports 100 Amp per phase and 30Vm withstand of rugged RF immunity. Furthermore the meter is built with varistor (VDR) that allows surge & lightening up to 13kV. Switch mode power supply is also avaiable for the option allowing the meter to work under low voltage down to 80V and below. The meter is manufactured by ISO9001 standards with stable quality and durability , fitting into very harsh and severe environments. .
With CA368 a utility or a service provider or a landlord is given freedom of setting free basic value, Time of Use (TOU) based tariff plans, emergency units, extra charge and debt collection principles into the meter and the vending system.
The meter is also available for a split type of connection to a customer interface unit as CIU. This feature greatly lowers the tamper and fraud by managing many main meters away from the customers.
Major Features
1) Surge protection for lightening
2) Immune to voltage dips and brownouts
3) Operates in four wires and three wires (optional)networks
4) 3 elements 4 quadrant measurement of active and reactive energy ( optional)
5) 20 digit (Standard Transfer Specification) STS encryption
6) IR optical and RS485 port for alternative data interrogation
7) Trips on overload and zero credit
8) Programmable power limit and low balance warning
9) Anti-tamper features such as opening cover alarm, SRE measurement, outage record, etc.
10) Recall 12 months historical usage data and last 5 entered token
11) Load profiling record at programmed intervals (optional)
Utility Benefits
a) Quick and easy to install using existing wires
b) Meter can be ordered with more communication facilities for AMR AMI features
c) Multi-rate and tariff plan settings on TOU basis
d) Information can be toggled by entering short codes
e) Meter provides critical information helping servcice providers improve their management
