The LM-3431 portable three phase PowerNodeTM 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 is packaged in a rugged, compact polypropylene IP67 protective case with provisions for locking that can withstand temperatures from -30°C to +80°C.
Data is stored in both internal non-volatile flash memory and up to 32Gb of removable SD card memory. Standard USB or optional Bluetooth local serial communications allows easy pre-installation configuration setup or operational verification. The cellular LTE 4G telemetry option provides a convenient and cost-effective way to transport data to SQL-based cloud servers, reducing the number of on-site visits. Configuration changes and firmware updates can be accomplished either locally or over the air.
The LM-3431 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 provides computational intervals of three seconds, 10 minutes and two hours in addition to many other interval durations.
