Main Features Multi-Tariff STS payment DLMS / COSEM Built-in load control Infrared port/ RS485 Tamper detection and record LCD display, read without power Active/reactive energy measurement Disconnects on overload and no credit Prepayment/post-payment mode switching Plug & Play module PLC /RF /GPRS /3G /4G Display Scroll button or STS keypad (alternative) Programmable power limit and low credit warning Dual power source swap between grid supply and solar Maximum demand measurement and load profiling (on request) 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.
