STS TOU Tariff Single Phase Keypad Prepayment Energy Meter
Product introduction
STE18-A is an STS Standard compliant, keypad type, automatically connection or disconnection prepaid electricity meter. It can be top up with Stronpay vending software directly and communicate with AMI system via RF-LoRa or PLC module.
Our electricity meters can be topped up directly using the Stron pay vending software and can be topped up remotely via the RF-LoRa and PLC module communicating with the AMI system.AMI is advanced metering infrastructure and is mainly composed of Smart Meter, communication system and equipment, meter database management system, and meter database management system.MDMS).
Application:
Counting electricity consumption over users’ period time. When the meter runs out of power, a warning is issued, and the main system can remotely control the switch and disconnect the network, so the user can no longer use the power. Only when the user recharges and enters the corresponding TOKENS, the network will be connected remotely and the user can continue to use it. In this way, the user can avoid the situation that the user defaults on the electricity bill but continues to use electricity endlessly, and help the supplier to better manage the user.
