YTL - prepaid meter 3*240(415)V Split Type ThreePhase 4 Module Electrical Meter PLC/RF/GPRS modem Nigeria standards
It is three phase four wire prepayment keypad meter with multi-functions, which measure forward and reverse power, total active power,remain credit and consumption credit etc. Inner meter use credit to calculate for managing well.Meanwhile, the prepayment meter has many communication options like RS485 ,RF, G3 PLC and GPRS communication. This meter must work with IHD together.
