Prepaid STS Meter

EM124033 IR RF Wire Communication STS Prepayment Meter with in-home Display

EM124033 is a Single Phase STS Single Phase Smart Prepayment Meter adopts the latest edition STS technology. Then STS smart meter becomes more robust, reliable, modern and innovative. Additionally, purchased kWh transmits by using a 20 digits code&STS encryption algorithm protocol. In this way, it enables to automatically shut off power supply in the event of fraudulent manipulation. And the events include opening of the terminal cover or exceeding of power, etc.Meanwhile, it supports both Standard Transfer Specification (STS) and Currency Transfer Specification (CTS) . When available credit exhausted, meter will disconnect power supply immediately and meters must not have the “emergency credit” function. It switches between postpaid and prepayment mode, and it offers Customer Interface Unit (CIU) as an optional device. With plug-in&play-out communication module among PLC, RF, GPRS or 3G, it realizes advanced AMI features.
