The PQ1 power quality sensor detects power quality problems on standard AC power mains. It is a single-phase monitor that can also be used phase-to-phase or phase-to-neutral on three-phase power systems. The PQ1 costs less than one-tenth as much as traditional power quality monitors. It quickly pays for itself by reducing service calls on automatic manufacturing systems, semiconductor tools, medical equipment, elevator controls, and other complex systems. You can select one of 16 pre-programmed industry-standard depth/duration response curves, covering voltage sags, swells, high-frequency impulses, and power interruptions.
