Main Features

Multi-Tariff DLMS/COSEM 20 digit STs encryption Tamper detection and record lmport & export measurement Infrared port/RS485/RF(optional) Disconnects on overload and no credit Programmable power limit and low credit warning Dual power source swap between grid supply and solar Maximum demand measurement and load profiling (on request) LCD display, read without power   Split Configuration for Increased Revenue Protection The meter consists of two parts, the MCU (Metering & Control Unit) and CIU (Customer Interface Unit). The MCU and CIU is linked via galvanically-isolated 2-wire communication cable or RF communication is also available on request. The CIU is installed within consumer’s home for prepaid token input and info inquiry, while MCU is installed in a meter cabinet away from consumers.
