Single Phase Smart Electric Meters Two Wire Commercial STS Keypad Meter
The DDSY168-G is a high end newly upgraded generation of smart electric meter that integrates high precision metrology with non-wired communication and contractual control principles. It is a single phase two wire electric Watt-hour meter that operates in prepayment and credit mode. The payment mode can be altered remotely by the command transmitted from head-end server. The meter displays full house metering data including V, A, PF, total consumption, balance and last 5 successfully entered tokens. It also records load profiling data at preset interval periods.
GSM GPRS connectivity allows DDSY168-g to transmit data real-time to the head-end server and utility to audit and control the meter remotely. This wireless solution adds value and benefits to both service providers and consumers.
