Optical RS485 3 Phase Electric Meter 10mm Cable STS Prepayment Meter Keypad Based
Calin designs and produces prepaid electric meters which are cost-efficient and ideal for the use in solutions for AMR/AMI at residential as well as industrial applications.Calin's prepaid meters own anti-tamper features .The CA368-G series is available with measurement of both active and reactive energy, and 2400 bps baud rate optical port for data extraction.
The CA368-G is the non-wired model of Calin's three phase prepaid meter. It is a four-wire, 100 Amp per phase, keypad based prepayment meter finished in a compact BS5685 footprint housing. The meter is manufactured in accordance with ISO9001 standards and IP54 rated protection class, in a wide voltage range ( Un -40% +20%) and improved RF immunity of 30V/m, allowing it to work in very harsh environments.
The GPRS feature of CA368-G enables the meter to connect to the back-end server via TCP/IP or vpn through point-to-point communication networks. Metering data and grid supply parameters can be remotely read and collected into the head-end server automatically as scheduled task. The meter Information can be toggled by punch in different combinations of codes.. Users can easily retrieve metering data from the display screen such as daily usage, monthly usage, present current and voltage, balance, and last five entered tokens.
Features
a) 20 digit (Standard Transfer Specification) STS standard encryption
b) Disconnects on overload and credit exhausts
c) Communication ports for easy data interrogation
d) Preset power limit and low credit warning level
