STE38-S Stron STS Standard Prepaid Split Three Phase Electricity Measurement Meter with CIU Hotsale

STE38-S STS Split Three Phase Prepaid Electricity Meter with CIU

With a specialized and high performance three phase measurement feature, STE38-S is composed of a Three phase prepaid electricity meter and the split keypad CIU(Customer Interface Unit) that provide a keypad for remote recharging and information checking which is the core competitiveness, advanced and easy to use . The communication between meter and CIU is Lora-RF which is effective and cost-friendly, the communication range is about 1km.

The CIU shares the same function as the keyboard on the meter itself, users can input 20 digits TOKEN for recharging or information checking. Various information can be toggled by input different combination of figures. Users can easily retrieve metering data such as daily usage, monthly usage, present current and voltage, balance, and last five entered tokens.

The meter can also be integrated with African local mobile money for prepayment, like M-pesa, MTN, Airtel through API(Application Programming Interface), which is the agreement connecting the third party APP and our Stronpay vending software. In this way, users can top up electricity credit by mobile money without leaving the house and could check information by their telephone at hand with internet accessibility.
