Keypad Prepayment Three Phase Electricity Meter Support Anti-Tamper
Product Introduction
STE38-A is a three phase prepaid electricity meter with STS standard,it has integrated keypad to recharge by TOKENS and check information by short codes. Its prepayment advantage is that user must pay first and then can use electricity,if no credits in the meter,electricity will be cut off.Stronpay vending software could be integrated to local mobile money payment platform via API, like M-PESA, Alipay, MTN, Airtel, etc.This energy meter can be both applied for residential and commercial place.It has low power consumption, high reliability, high precision and stable function, convenient to use and maintain.
Three phase watt-hour meter is applicable to commercial buildings and public infrastructure buildings to realize the measurement and statistics of electric energy consumption in different areas or different loads in buildings. Three phase watt-hour meter is suitable for the statistics and internal accounting of electric energy consumption of different production lines or loads in industrial buildings.
