Three Phase Keypad Prepayment Electricity Meter
The RHF368J offers options for extended surge protection for lightening up to 13kV
and a wide voltage working range -50% ~ +130%. It is intended for unstable grid
voltage environment such as African and Central American continent where
brownouts and voltage dips are extremely frequent. The meter works in a three
phase four wire network with 100 Amp per phase, and 30 Vm withstand of RF
immunity, allowing it to operate in very severe environments. It is a perfect
revenue protection device for sub-metering of residential, light commercial and
industrial applications.

Split Configuration for Increased Revenue Protection
The meter consists of two parts, the MCU (Metering & Control Unit) and UIU (User Interface Unit). The MCU and UIU is linked via galvanically-isolated 2-wire communication cable or Radio Frequency (RF) communication is also available on request.
The UIU is installed within consumer’s home for prepaid token input and info inquiry, while MCU is installed in a meter cabinet away from consumers.
