GSD7666 Single Phase Prepaid Keypad Electricity Meter

Single Phase Prepayment Keypad Electricity Meter

The DDSY168 is used for a wide rang of applications, due to an improved dynamic range allowing a basic current of 5 Amp while retaining a maximum current of 80 Amp and extended functional features.

Main Features

  • 20 digit (Standard Transfer Specification) STS encryption
  • Detection of significant reverse energy (SRE)
  • IEC62056-21 compliant optical & RS485 port allowing for easy data interrogation
  • Disconnects on overload and no credit
  • Prepayment and credit mode hot swap
  • Programmable load limit and low credit warning
  • Detection and record tamper event such as opening cover, reverse connection, black-out
  • Easy access to 12 months historical consumption data and last 5 token entered

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.

AMR/AMI Smart Metering Function (on request)

  • Easy connection to User Interface Unit (UIU) for split type applications
  • PLC/ RF / GPRS communication with a head-end AMR/AMI server
  • Time of Use (TOU) , multi-tarif, holiday setting.
  • Advanced load control and disconnection features
