Three Phase Keypad Prepaid Electricity Meter

The CA368 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.

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, black-out
  • Dual power source working on both prepayment and credit mode
  • Maximum demand measurement and load profiling (on request)
