Model Number:
STE38-S
Ste38-s has professional and high-performance three-phase metering function, which is composed of three-phase prepayment watt hour meter and sub key CIU (customer interface unit). It provides keys for remote recharge and information query, which is its core competitiveness, advanced and easy to use. Lora radio frequency is used for communication between the instrument and CIU, which is effective and low cost. The communication distance is about 1km.
The keyboard function of CIU is the same as that of the meter itself. The user can input a 20 bit token to recharge or query information. Various information can be switched by inputting different graphic combinations. Users can easily retrieve metering data such as daily usage, monthly usage, current current and voltage, balance and last five input 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.
