Din Rail with RF, Split type(MCU+CIU)
The DDZY876 is used for a wide range of smart prepaid metering applications, due to an improved dynamic range allowing a basic current of 5 Amp while retaining a maximum current of 100 Amp and extended functional features. 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 & VTC port allowing for easy data interrogation
Disconnects on overload and no credit
Operate in both prepayment and credit
Programmable load limit and low credit warning
Detection and record tamper event such as opening main cover&terminal cover, current reverse, missing neutral, bypass, power down
Downlink communication (between MCU and CIU) is RF
Digits: 6 integers + 2 decimal
Ultrasonic welding for main cover and base
