| Numero sa Modelo | Single-phase Keypad Smart Energy Meter GSD7666-G |
| Nasodnong peryedyo | 50/60Hz |
| Serye | GSD |
GSD7666 - G usa ka advanced single-phase smart meter nga may modular design aron sa eksaktong pagkuha sa energy para sa komersyal & residential nga mga customer, may wide range of functions, smart measurement & flexible communication modules para sa remote reading & management. Kini mahimong gamiton alang sa prepayment (compliant with STS standard) o postpayment applications (optional), samtang adunay outstanding anti-tampering functions sama sa detection of terminal cover opening aron makatubag ang utilities sa revenue protection. Kini makipag-communicate sa CIU o DCU (Data Concentrator Unit for AMR/AMI system) pinaagi sa different communication modes sama ngadto sa PLC/GPRS/3G/4G/RF batas sa requirements.

Split-type Structure for Anti-tampering Protection
Ang CIU (Customer Interface Unit) usa ra ka optional, linking to the MCU (Metering & Control Unit) with communication modes of M-bus, PLC or RF based on requirements. Ang CIU is installed inside the customer's home for inputting prepayment token and searching for information, while the MCU is normally installed in a meter enclosure away from the customer's home.
