The energy meter is suitble for Solar system, The meter can display Positive KWh and reverse KWh.
DDS238-2 SW type singe phase din rail kwh meter 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 )
