Three-phase Four Wire Electronic Kwh Meter

The Three-phase Four Wire Electronic Kwh Meter adopts the up-to-date microelectronic technology, which is used to measure active electric energy or reactive electric energy of three-phase A.C with a rated frequency of 50/60Hz.
Functions and features:
-This type of three phase kWh meter is used to measure three-phase active electric energy, needless to calibrate after long-term operation.
-Super performance. It could deliver unaffected performance if two (any two of the four wires) phases fail to work.
-Wide temperature serving range.
-Standard "impulse" LED indication, "Reverse current" LED indication and "phase loose" LED indication.
-Infrared data communication terminal or RS485 data communication terminal if required.
-Step motor type impulse register display, and LCD digital display and LED digital display (visible in darkness) is also available if required.
-Extended terminal cover is equipped protecting from electricity-theft.
-Phase voltage pothook can be connected upon request in the internal of meter for safer uses.
