FEFA - Model FE-STS Series - Static Transfer Switches
The FE-STS series static transfer switches are designed to enhance power supply reliability by providing seamless transfer of critical electrical loads to either of two independent AC power lines. This system continuously monitors dual AC input lines, and in the event one falls below configured tolerance levels, it automatically shifts the load to the other line, ensuring uninterrupted power supply for critical processes. This approach minimizes process interruptions and the impact of power fluctuations and short interruptions. The system is crucial for applications where power stability is vital and utilizes advanced technology to ensure operational continuity by offering an always-available backup power source. It contributes significantly to improved power availability and reliability for sensitive and critical operations in various industries.
FE-STS series is the state-of-the-art method of increasing the power supply reliability by protecting electrical loads and increasing their availability using FEFA Power solutions static transfer switch, seamlessly transferring uninterruptedly critical loads to either of two independent AC power lines. The system continuously monitors two AC inputs, if any goes out of the configured tolerance, the FE-STS transfers the critical load to the other available source. By increasing the power availability, critical loads will keep on running without the possibility of process interruptions, using FE-STS34/FE-STS33 series static transfer switches you reduce the effects of interference and short interruptions, and a backup power source is gained.
