The LM-3431-A portable three phase analyzer / recorder is fully Class A compliant with the IEC 61000-4-30 power quality standards. Class A measurement methodology allows operators to easily identify and isolate power system problems and anomalies with confidence.
Intended to be installed outdoors or indoors, the LM-3431-A is packaged in a rugged, compact polypropylene IP67 protective case with provisions for locking that can withstand temperatures from -40°C to +70°C.
The LM-3431-A provides 600 VAC, three phase monitoring with remote alarm exceedance notifications. Three voltage channels (Phases A,B,C) and four current channels (Phases A,B,C, Neutral) are sampled simultaneously at a rate of 128 samples per cycle at 60 Hz. Per IEC 61000-4-30 Class A specifications, the LM-3431-A provides computational intervals of three seconds, 10 minutes and two hours in addition to many other interval durations.
