Dual relay Multi tariff DLMS/COESM Infrared port/RS485 Tamper detection and record LCD display, read without power Active/reactive energy measurement Double CT for Phase and Neutral line Disconnects on overload and no credit Prepayment / post-payment mode switching Plug & Play module PLC/ GPRS/ 3G/ 4G/ RF Display scroll button or STS keypad (optional) Programmable load limit & Low credit warning   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.
