STS Split Keypad Three Phase GPRS Prepaid Energy Meter with CIU

Split Keypad Three Phase Prepayment Electricity Meter

The CAM368-S offers options for extended surge protection for lightening up to 13kV with a build-in 6.5kA VDR and a wide voltage working range. It is intended for unstable grid voltage environment such as African and Central American continent where brownouts and voltage dips are extremely frequent. The meter works in a three phase four wire or three wire (optional) network with 100 Amp per phase, and 30 Vm withstand of RF immunity, allowing it to operate in very severe environments. It is a perfect revenue protection device for sub-metering of residential, light commercial and industrial applications. 

 

Features

  • 20 digit (Standard Transfer Specification) STS encryption
  • Up to 13kV/6.5kA surge protection for lightening and other line surges
  • IR optical & RS485 port allowing for easy data interrogation
  • Disconnects on overload and no credit
  • Programmable power limit and low credit warning
  • Tamper detection and event record such as opening cover, reverse connection
  • Dual power source working on both prepayment and credit mode
  • Maximum demand measurement and load profiling (on request)

 

Split Configuration for Increased Revenue Protection

The meter consists of two parts, the MCU (Metering & Control Unit) and UIU (User Interface Unit). The MCU and UIU is linked via galvanically-isolated 2-wire communication cable. Power line carrier (PLC) and Radio Frequency (RF) communication module is also available on request.

The UIU is installed within consumer’s home, while MCU is installed in a meter cabinet away from consumers.

 

User Benefit

  1. Easy to install for both new reticulation and retrofitting due to BS mounting
  2. Low operational and inventory cost
  3. Can be ordered with RF communication Module for AMR/AMI features
  4. Meter provides various valuable information by punching in Calin's short codes
  5. Flexible payment control setting
