Multi - Rate Power Three Phase Energy Meters Keypad Digital Electricity Meter
The CA368 is a keypad based STS prepayment three phase watt-hour energy meter. It is the basic type of Calin's poly / triple phase prepaid meters. The meter allows 100 Amp per phase and 30Vm withstand of rugged RF immunity, fitting into even very harsh environments. It is built in a compact BS footprint housing, ideal for both new and retrofitting installations. The meter is manufactured by ISO9001 standards, and it is used for large residential houses, small commercial and industrial environments.
The CA368 allows the service provider and landlord to set starting value, up to 4 rates on Time of Use basis, free basic units, emergency units, extra charge and debt collection principles. The meter offers the utmost revenue protection and collection convenience.
The meter is also available with a split type of connection to a customer interface unit as CIU. CIU is a keypad based display unit. It is installed with customer's premises with main meter locked away . This feature greatly lowers the tamper and fraud by managing many main meters in one place away from the customers.
Major Features
a) Operates in four wires and three wires networks
b) Multiple measurement channels with full quadrant energy measurement
c) 20 digit (Standard Transfer Specification) STS encryption
d) RS485 and infrared optical for data extraction
e) Disconnects on overload and no credit
f) Programmable power limit and low credit warning
g) Tamper and fraud detection such as opening cover, reverse connection, black-out
h) Recall 12 months historical usage data and last 5 entered token
Utility Benefits
1) Easy to install and deploy, especially for retrofitting installations
2) Communication port prepared for AMR AMI functions
3) Build-in clock allows for time based multi-rates
4) Retrieve historical data locally and remotely
5) Full house metering data for better management
