Delivering Power Reliability
For over three decades, PQSI has been a trusted leader in power quality solutions, dedicated to keeping industrial facilities operational despite the challenges of voltage fluctuations. Our journey began with a mission to address a pervasive issue in industrial settings: momentary voltage drops that disrupt processes and cost businesses millions. Through innovation and a commitment to excellence, we developed the Coil-Lock—a revolutionary device that ensures magnetic contactors remain engaged during voltage dips, transforming how industries manage power reliability.
Since its inception, PQSI has sold over 30,000 Coil-Locks worldwide, serving industries from manufacturing to energy. These devices have saved businesses millions by preventing production losses—some facilities once lost a day of output per week due to voltage drops. Our lifetime guarantee underscores our confidence in the product.
