Single Phase Power Line Carrier Prepayment Electronic Meter

Model: DDSY1282
Name: Single Phase Power Line Carrier Prepayment Electronic Meter
Introduction: high precision, high reliability, long service life, low power consumption, light weight

Adopting special integrated circuit and manufactured with advanced SMT and re-flow soldering technology, DDSY1282 Single Phase Power Line Carrie Prepayment Electronic Meter can be used for measuring active and reactive electric power that requires both timesharing and prepayment. The circuit design and component selection allow maximum tolerance thus the meter can run with stability, accuracy, high overload, low power consumption and reliability.

♦ Positive/negative active energy consumption measurement( negative active energy consumption will be counted into positive active energy consumption)

♦ CPU card prepayment, purchasing before using.

♦ Alarm at low remaining power to remind user of timely purchasing

♦ Carrier Wave communication through power lines with automatical relay function

♦ The meter can allow credit consumptions and the debit can be subtracted in the next transaction

♦Load Control function and load can be set

♦ Real time clock

♦The real status of relay can be checked automatically.

♦Energy consumption frozen and stored function

♦ Self verifying function

♦ RS485 Communication and infrared.

♦ Display: LCD display
