Power Standards Lab's PQube pinpoints the root causes of electrical malfunctions
The PQube from Power Standards Lab records power quality events and energy consumption in automated plant equipment. The PQube is designed to pinpoint the root causes of electrical malfunctions in plant-critical PLC systems, sensors and alarm systems, and other sensitive plant equipment. The PQube is also designed to accurately track energy and carbon emissions.
The PQube recorder is one tenth the size and one fifth the cost of comparable traditional instruments. It has an easy-to-use color organic LED (OLED) display and Ethernet-based remote monitoring, e-mail reporting, G3 wireless communication and there is no software required. All recordings are on standard digital camera SD memory cards, using open file formats.
The PQube measures voltage and current with lab-grade accuracy. It detects all power quality glitches including voltage sags, interruptions, voltage swells, harmonics, frequency variations and high-frequency impulses. The technology automatically adjusts to every frequency — 50 Hz, 60 Hz, and 400 Hz — and every standard voltage in the world, from 100V in Japanese homes to 690V in Australian mines. The PQube works with single-phase and three-phase systems.
