JOY311 Integrated Triple-Phase Prepaid Electricity Meter provides an integrated solution for kWh measurement and prepayment. Credit and management data is transferred from a point of sales (POS) to the meter via a 20-digit numeric token that is generated using the Standard Transfer Specification (STS) encryption protocol. The token is entered to the meter via a keypad. The meter is ideal for large residential home and small commercial application.
