Three Phase Din Rail Multi-function Enegy Meter, Type DT(S)S238-4 ZN

The meter is used in three phase four wire /three phase three wire /two phase three wire power grid. The meter is designed to measure AC active energy and reactive energy with
time of use (TOU) function (the power flow of sharp time ,peak time, flat time and off-peak time) and variable parameter. All of its functions comply with the relative technical
requirement for class 1 three phase watt hour meter in IEC61036 and its data communication rules obey the requirement of DL/T645 or MODBUS-RTU. It is a long life meter with the
advantage of high stability, high over load capability, low power loss and small volume.

Basic Function 
1.LCD display , backup battery for LCD display at power failure 
2.Bi-directional total active/reactive energy measurement and TOU active/reactive energy measurement ,reverse active/reactive energy measure in the total active/reactive energy 
3.The meter also display three phase real voltage, real current, real power, real power factor, real frequency, real time and date
4.The meter has 4 kinds of tariff defined as sharp,peak ,flat and off-peak. the meter can be programmed as single tariff , double tariff and three tariff or four tariff. 
5.The meter has 14 programmable interval tables, of which can set up to 14 intervals as four tariff during 24 hours，The minimum units of each tariff interval can be set up as 1
minute
6.Four-quadrant reactive energy measurement, it should read from RS485 port
7.Pulse LED indicates working of meter，Pulse output with optical coupling isolation
8.Loss phase indication in LCD
9.Energy frozen monthly(last 12 months),all data store for 15 years at power failure
10.Infrared and RS485 communication port
11.The meter can automatically switch calendar and leap year
12.Event log
13.35mm din rail installation 

Optional Function
1.the meter can measure and display the total forward/reverse active/reactive energy
2.Accumulative working time display and reset total active energy function (these two data can be reset to zero with keypad in meantime)  
3.LCD display with backlight
