SEO-1
Possible designs: with current transformer, shunt circuit, with complex current sensor, with electromechanical readout, with LSD, two current sensors.
Accuracy class 1 or 2.
Designed for measuring electric energy consumption in two-wire AC circuits with 50Hz frequency. Meters are made using surface-mounting technology from components of world leaders and at modern equipment. All meters, even when phased differently, will only increase reading.
All meters comply with accuracy limits when load has a constant component.
Electric energy consumption is displayed on an LCD or an electromechanical readout protected from electromagnetic interference.
Telemetric port allows to use SEO meters in any kind of automated systems.
