Se prensip la k ap travay nan STS ki baze sou demann lan pou oblije chanje pouvwa. Lè ekipman pou pouvwa prensipal la echwe oswa echwe, STS can automatically switch the load from the main power supply to the backup power supply to maintain continuous power supply. The main steps include: 1 Monitoring: STS will continuously monitor the status of the main power supply, including parameters such as voltage, abitid, phase, elatriye. 2. Deteksyon fòt: When STS detects a fault in the main power supply or does not meet the preset working range, it will immediately respond. 3. Switching decision: STS determines whether power switching is necessary based on the fault detection results. 4. Oblije chanje operasyon: If it is determined that switching is necessary, STS will control the switching process. It will disconnect the main power supply and ensure that the backup power supply is ready, then connect the load to the backup power supply. 5. Switching completed: Once the switching is completed, STS will monitor the status of the backup power supply to ensure it can provide power normally. Collaboration with UPS
