Details
GSD7666-WJ1 is a single-phase two-wire smart energy meter integrated with high-precision metrology & excellent wireless communication technology. The meter case has protection against 13kV surge & lightning and anti-interference against RF of 30Vm, being able to operate in very severe environment for residential, commercial & industrial applications.
Modular Design
GSD7666-WJ1 is equiped with a plug & play module for communication. This modular design provides power utilities and power service providers with a free choice of PLC/RF/GPRS communication and 3G/4G LTE cellular data networks according to local infrastructure conditions,which greatly reduces their operational costs.The module can be easily removed and replaced without changing the entire meter.Through its wireless communication with an AMR/AMI system’s back-end server,the power utilities & power service providers are capable of making management settings including, but not limited to,free basic unit,emergency credit, prepayment ELECTRICALPARAMETER control, power limit, tariff rate & Automatic Meter Reading,etc.
Main Features
·Plug & Play GPRS/4G communication module
·DLMS/COSEM compliant
·Double relay on demand
·Disconnecting on overload & no-credit condition
·Programmable warning of load limit & low credit
·Detection & recording of tampering events like cover opening, reverse connection & power failure
·Double CT for phase & neutral line
