Comprehensive protection: The relay guards connected equipment against overvoltage, undervoltage, and overcurrent, helping prevent damage and downtime in fluctuating electrical networks. Immediate power cut: If voltage or current exceeds safe limits, it disconnects the load quickly to minimize damage and safety risks. Dual LED display: Realtime voltage and current are shown on two LEDs for quick monitoring and informed power decisions. Efficient and durable: Low standby power under 2 W and a long mechanical life over 100,000 cycles support reliable, lowmaintenance operation. Compact form factor for easy panel integration. Compatibility and installation: Designed for standard AC loads in control panels, power strips, or equipment racks; suitable for typical mains environments and simple wiring with standard terminals. Use cases: Home electronics protection: TVs, gaming PCs, and AV receivers during voltage fluctuations. Office and small business: Printers, scanners, routers, and network devices. Light industrial: Motors, drives, pumps, and sensors in control cabinets.
