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
