PQ1
The PQ1 is a compact and cost-effective power disturbance sensor that instantly detects and reports power quality events such as sags, dips, swells, and impulses. Simply connect the PQ1’s input terminals to the AC power line feeding your system, and wire its relay outputs to the digital inputs of your control system or monitoring software. Every disturbance on the mains will be captured and reported in real-time, enabling your system to react or log issues immediately. Designed for ultra-low cost but delivering high operational value, the PQ1 is the ideal choice for simple yet effective power quality monitoring in automation, control panels, and embedded systems.
