[Automatic loading transmission] The load immediately goes from the primary safety source source source when defaulting electricity or voltage fluctuations. [Personalized parameters] Pray the different power sources and define the voltage thresholds for automatic switching to meet specific requirements. [Precise control] Adjust the conversion time, the reset time, the protection against overvoltage / sub-tension for a stable electricity transmission. [Long -term construction] Made of fire -fire PC material for high sensitivity, precise measurement and generation with low heat. [Different applications] Ideal for use in commercial, industrial buildings, facilities, data centers and basic stations.
