    Extended terminal cover backplate, Prepaid Electricity Meters , Sts Digital Electric Meter voltage dip stable


    The CA168 is a one phase two wire prepaid electricity meter compliant with STS prepayment standard. It is finished in a compact, keypad-based  BS5685 footprint housing with steel backplate. It maintains the rugged RF immunity withstand of 30V/m and IP54 rating, up to 13kV surge & lightnening protection, and down to 50V operatable voltage, allowing it to be installed in very harsh and voltage-dip or brownouts frequent environments, such as in Afrcia and Central America continents. The meter is used for residential, light commercial and industrial environments and is ideal for submetering and tenants  applications. 


    The meter provides one-pack solution for kWh measurement and prepayment. Credit and all prepayment data is encrypted within a 20-digit numeric token that is generated using the Standard Transfer Specification (STS) encryption protocol. The token is input into the meter with a 4x3 three-color keypad.  Information as V, A, PF, daily, monthly usage data, etc can be toggled by Calin's short codes. A utility or a service provider can make settings with the meter such as emergency unit, free basic unit, debt collection, billing cycles, power limit, low balance warning, etc.




    1) 20 digits STS compliant encryption

    2) Reliable Surge & lightening protection

    3) Operates under extrem low voltage

    4) Detection and measurement of reverse energy( SRE )

    5) Operate in prepayment and post-payment mode

    6) Disconnects on overload and zero credit

    7) Tamper proof

    8) Reserved for wireless communication with a head-end (HES) AMR AMI server(optional)


     Key benefits

    a) Quick and easy to install for new reticulation and retrofittings

    b) Multi-rate and usage record on Time of Use (TOU) basis

    c) Flexible management settings

    d) Upgradable and scalable to high end smart metering infrastructures

    e) Reduce operational and inventory cost due to wide voltage range, surge protection and long service life design
