The CA368-S is split type keypad prepaid electricity meter compliance with STS (Standard Transfer Specificatio) prepayment protocol. The CA368-S have two parts, MCU (meter) and CIU (Customer Interface Unit), the CIU connect the MCU by RF communication, which can prevent effectively anti-tamper actions, because you can install the MCU (meter) in a locked box or on the top of electric pole and only give the CIU to the users, the users even cannot touch the meters so that they cannot steal the power.
Thanks to the built-in RF communication module, the meter can not only connect with the CIU, but also can upload the data to the data concentrator. And then the data concentrator can upload the data to our system by GPRS because of the built-in RF and GPRS module in the same time in the data concentrator.
Main Features
• 20 digits code for recharing credits
• Up to 13kV/6.5kA surge protection for lightening and other line surges
• Compliance with IR port and RS485 communication port
• Open the relay automatically if the credit be used up
• Programmable power limit and low credit warning
• Tamper actions record
• Different Tariffs for dual power source solution is avaiable
• Maximum demand measurement and load profiling (on request)
User Benefit
• Easy to install and maintance
• More convinent for operating of recharge thank to the CIU.
• Can be ordered with PLC/ RF/ GPRS/GSM com munication for AMR/AM I features
• Meter provides various valuable information by punching in Calin's short codes
• instant investment back, debt collection
