STS(Static Transfer Switch) in UPS system, is an automatic static switching equipment designed to transfer critical loads between two independent AC power sources without interruption or with a transfer time of less than a cycle (20ms) to ensure permanent power availability when a power outage occu

In many important occasions, the reliability of the load of electricity consumption is very important. In order to improve the reliability of the load, the general power supply system adopts dual power supply, such as dual main power, one main power and UPS. However, the more reliable method is to u

In an conventional UPS configuration with N+1 configuration, where N=2, we put in place a parallel configuration with 3 UPSs in parallel and an common output from the parallel bus is taken and provided as a input to the critical loads.Although this configuration provides the redundancy at UPS level,
