- ● The system host and extension are manufactured by advanced SMT production process.
- ● The system adopts a special approximation optimization algorithm to intelligently select and control the different work of each extension.
- ● The use of work in the nationally recognized wireless frequency band wireless data transmission technology, the use of multi-frequency frequency hopping technology for networking, communication, data transmission is accurate and reliable, low power consumption.
- ● Each extension of the system adopts a special high-power magnetic latching relay to form a switch assembly, and the system itself runs with low energy consumption.
- ● The extension has the function of zero line live detection, which can quickly locate the zero line live fault point.
- ● The whole system should have encryption control to prevent the switch from switching at will and eliminate potential safety hazards.
