The energymeter is suitble forSolar system, The meter can displayPositive KWh andreverse KWh.
DDS238-2 SW type singe phase din rail kwhmeter is designed to measure single phase two wire AC active energy and variable parameter. All of its functions comply with the relative technical requirement for class 1 single phase watt hour meter in IEC61036. It is a long life meter with the advantage of high stability , high over load capability , low power loss and small volume .
Basic Function
LCD display with backlight
Bi-directional total active energy ,reverse active energy measure in the total active energy
The meter also display real voltage , real current , real power , real power factor , real frequency
Pulse LED indicates working of meter .Pulse output with optical coupling isolation
35mm din rail installation
Optional Function
the meter can measure and display the total forward/reverse active energy
reset energy function (the reset energy kWh display is dependent with the total energy display, this reset will not affect the total energy )

1 Real Frequency Hz
Range: 00.00~99.99
2. Reset Energy KWH(Only reset Energycan reset to zero, Total energy can't reset to zero)
Range: 00000.0~99999.9
What is the reset Energy KWH?
1.You can check How manyelectricity consumptionin anyperiods of time.
2.For example: If you want to know your electricity consumptionin one hour. Reset tP to zero, then let the energy meterworks, after an hour, tP will display the tP Energy. Then you know how is theelectricity consumption in one hour. Of course, you can reset the tP to zero again to check in any periods of time'selectricity consumption.
3.Advantage: You know whenelectricity consumption is much, then to change your electricity usage. Savingelectricity.
