 DDSY566-L01

 

 
Single phase prepayment watt-hour meter (LCD)
¡¡ ¡¡
    
    
DDSY566 single phase prepayment electronic watt-hour meter adopts LSI, latest micro-electronic technology & SMT technique, with advanced processing and simple structure and modern special IC chip to raise the meter¡¯s dynamic working scope. Long-life and high-reliability components are adopted to ensure the long-term operation stability of the energy meter. It used for measuring rated frequency 50Hz/60Hz active energy with high accuracy and little power loss, meanwhile, realizes the functions of prepayment management and load control that pay for energy first & use it afterwards.
     DDSY566 Single Phase prepayment electronic watt-hour meter conforms to the standards as follow: GB/T 17215-2002 (IEC61036-2000)
