Demand calculating.
Auto detection.
Realize use
rs’ load detecting and controlling.
Detect grid parameters including real-time power, voltage, current and power factor.

1.1.5 Major Features
Prepaid mode- it is a power consumption mode by paying first and using electricity later.
APL SEM 3P V2 Three-phase Keypad Prepayment Energy Meter takes amount as its
electricity billing. In conditions of prepaid mode, electricity consumer purchases amount
at first and the meter subtracts the remaining credit amount equivalent to the
consumption. When remaining amount is 0 or the overdraft energy allowed by both
parties, it will send out power off signal to control load switch automatically cut off.
APL SEM 3P V2 Three-phase Keypad Prepayment Energy Meter adopts CTS algorithm,
which has a set of security management system with a high-level security and is
completely compatible with the CTS management system deployed in Bangladesh
