Application:
DDZY2031 series single phase smart meter adopt large-scale integrated circuits and digital technology. we design smart meter is based on Smart Grid, Informatization, Automation, Interactive. This meter is according to standard:GB/T15284-2002, DL/T645-2007, Q/GDW355-2009, Q/GDW354-2009, Q/GDW364-2009,Q/GDW365-2009
Products feature:
1).With positive and negative active power, combined total active power and sub-rate electric energy metering and storage functions, combined active power characteristics can be set up
2).It has function of remote control fee
3).It hasstorage functions of 12 period settle accounts, it can store positive and negative active power data for total and sub-rate electric energy.
4).It hasactual time test function for voltage, current, power and power factor.
5).It has the function of timing, instantaneous, agreement, whole point and day freezing, and the character of freezing can be setted.
6).It has two set of rate time zones, timesheets that can be automatically converted at agreed time.
7).It display power off, it can be roused by button orinfrared remote
8).With infrared communication port and carrier communication port, it is convenient to exchange data with the outside world
9).It adopts software meter checking automatically, high checking speed and more accuracy.
10).It adopts the integrated design of cover and cover plate. It is novel in shape, beautiful and practical in appearance.
11).It mainly use in smart grid electric net single phase user for calculate the electric energy.
