Single phase three
wire prepayment watt-hour meter |
| |
| |
DDSY566
single phase three wire 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 three wire prepayment electronic watt-hour meter
conforms to the standards as follow: GB/T
17215-2002 (IEC61036-2000)
