| Numero ng Modelo | Single-phase Keypad Smart Energy Meter GSD7666-G |
| Larawan na Pagsasahimpapawid | 50/60Hz |
| Serye | GSD |
Ang GSD7666 - G ay isang advanced na single-phase smart meter na may modular na disenyo upang ma-accurately measure ang enerhiya para sa mga komersyal at residential na customers, may malawak na saklaw ng mga function, smart measurement, at flexible communication modules para sa remote reading at management. Ito ay maaaring gamitin para sa prepayment (compliant sa STS standard) o postpayment applications (optional), kasama ang outstanding anti-tampering functions tulad ng detection ng pagbubukas ng terminal cover upang matulungan ang utilities sa revenue protection. Ito ay maaaring mag-communicate sa CIU o DCU (Data Concentrator Unit para sa AMR/AMI system) sa iba't ibang communication modes tulad ng PLC/GPRS/3G/4G/RF batay sa requirements.

Split-type Structure for Anti-tampering Protection
Ang CIU (Customer Interface Unit) ay optional, linking to the MCU (Metering & Control Unit) with communication modes of M-bus, PLC or RF based on requirements.
Ang CIU ay inilalapat sa loob ng bahay ng customer para sa input ng prepayment token at paghahanap ng impormasyon, habang ang MCU ay karaniwang inilalapat sa isang meter enclosure malayo sa bahay ng customer.
