Overview:

DTS, DSS series three-phase electronic watthour meters(hereafter:watthour meter), 

using advanced ultra-low power consumption solid state integrated circuit technology

 and SMT advanced technology, used for measuring AC three-phase active energy, 

widely used in measuring the power consumption of enterprises, substations,

 power plants transmission and distribution and distribution automation.

Its performance meets the technical requirements of three-phase electronic electricity meters in 

GB/T 17215.321-2008 "Special Requirements for AC Measuring Equipment Part 21: Static active power 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.

The meaning of watthour meter:

Watt-hour meter, device that measures and records over time the electric power flowing through a circuit.

 Although there are several different types of watt-hour meters, each consists essentially of a small electric motor and a counter.

Functional characteristics:

2.1 Accurate and stable electric energy metering, the whole machine after leaving the factory without adjustment. 

Three-phase power supply, one or two phase power off, measuring accuracy is not affected, and has a lack of phase indication function.

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.

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

2.3 The 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.

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

FAQ:

Q:What is watt and Watthour?

A:A watt-hour is the unit of measurement used commercially because it's easier to quantify.

 It's the equivalent of the total energy supplied if electrical power of one watt is maintained for one hour; that's equal to 3600 joules.
