PSL PQUBE-02-0000 690V 50/60Hz AC Power Monitor Offers

The PQube AC Power Monitor is a 690V, 50/60Hz power monitor for single- and three-phase systems. This power quality monitor records daily, weekly, and monthly trends, and It features time-triggered snapshots, impulse detection, and the frequency event monitoring. The PQube also provides waveforms and RMS graphs of voltage dips, swells, and interruptions and monitors THD, TDD, RMS Flicker, and voltage and current unbalance. The PQube features two analog inputs, two temperature/humidity monitoring channels, and up to 4 relay outputs. The PQube automatically saves data onto a standard SD card, so no software is required. The PQube includes one signal relay.
