1. Overview:

DDS series single-phase electronic watt-hour meter (hereafter: Electronic Energy Meter 1P)

 adopts advanced ultra-low power consumption solid-state integrated circuit technology and SMT advanced technology,

 which is used to measure single-phase active power of AC.

 It is widely used to measure the electricity consumption of residential buildings, offices, shops, etc.

Its performance meets the technical requirements for single-phase electronic watt-hour meters in GB/T 17215.321-2008 "

Special Requirements for AC Measuring Equipment Part 21: Static active watt-hour meters (Grade 1 and 2)". 

With communication, the protocol complies with DL/T 645 -- 1997 or DL/T 645 -- 2007 Multifunctional Electricity Meter Communication Protocol.

2. Functional characteristics:

2.1Electric energy measurement is accurate and stable, the whole machine does not need to adjust after leaving the factory, 

can prolong the verification cycle, greatly reduce the power department testing and verifying the workload of electricity meters,

 reliability is significantly improved compared with similar products.

2.2 Bidirectional measurement function, accurate measurement of positive and reverse bidirectional electric energy, 

with the total electric energy accumulated power, with the function of preventing electric theft.

2.3Photoelectric isolation of electrical pulse output signal, error detection can be carried out, light tube indicating electricity use.

2.4The instrument has the advantages of wide load, high accuracy, high reliability, high sensitivity, flat error curve, small size, 

light weight, low power consumption, strong overload capacity, easy installation and so on.

2.5 If the instrument communicates with infrared or RS485, ask the manufacturer for the communication data.
