Pluggable communication module(4G/GPRS/RF/PLC).
Consisting of two parts, the MCU(Metering & Control Unit) + CIU( Customer Interface Unit)
The DTZY876 is used for a wide range of smart prepaid metering applications. Is split type, consisting of two parts, the MCU(Metering & Control Unit) and CIU( Customer Interface Unit). The CIU is installed within consumer’s home, while MCU is installed in a meter cabinet away from consumers.
DLMS/COSEM standard compliant.
IEC62056-21 compliant optical port &VTC allowing for easy data interrogation.
Operate in both prepayment and postpayment.
Measurement of electrical parameters (Active energy, reactive power, current, voltage, maximum demand.)
Programmable load limit and low credit warning.
Detection and record event such as opening main cover&terminal cover, current reverse, bypass, phases&neutral interchangeable, neutral missing, phase missing, power outage, magnetic disturbance,last gasp.
Downlink communication (between MCU and CIU) is RF/PLC, uplink communication 4G/GPRS/RF/PLC.
Digits: 6 integers + 2 decimal.
With replaceable battery.
