Ensure uninterrupted and reliable power supply with the CHLT-GX3 Automatic Transfer Switch (ATS), designed for seamless switching between main and standby power sources in three-phase power systems. Constructed with a flame-retardant PC shell, this ATS offers high safety, precise operation, and durable performance, making it ideal for commercial, industrial, medical, data center, and communication applications requiring continuous power. Key Features: · Automatic Transfer Function: Automatically transfers load from the main power supply to the standby source when voltage abnormalities or power failures occur, with priority sequence L1 > L2 > L3, ensuring smooth and stable power transitions without fluctuations or interference. Upon recovery of the main supply, the load is seamlessly switched back to maintain system stability. · Flexible and Customizable Settings: Freely prioritize mains power, generator, or inverter inputs and set voltage thresholds for automatic switching during under-voltage or over-voltage conditions. The switch speed is adjustable from 1 to 600 seconds (default 30 seconds), allowing tailored performance to suit specific power management needs. · Adjustable Protection Parameters: Transfer time, reset time, over-voltage, under-voltage, and overcurrent protection parameters are all configurable within specified ranges, providing enhanced control and protection for connected equipment. · Flame Retardant and Durable Construction: The high fireproof PC material housing offers excellent safety by resisting combustion, while delivering sensitive operation, accurate voltage measurement, and minimal heat generation for reliable long-term use. · Wide Application Range: Perfect for power systems requiring stable and continuous power supply, including commercial and industrial buildings, medical facilities, data centers, and communication base stations.
