The LM-3431-S portable three phase power quality analyzer / recorder allows operators to easily identify and isolate power system problems and anomalies with confidence.
Intended to be installed outdoors or indoors, the LM-3431-S is packaged in a rugged, compact polypropylene IP67 protective case with provisions for locking that can withstand temperatures from -40°C to +70°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/M1 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-S measures 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.
