- 1-Ph out / 3-Ph out, 1/2/3/4 Poles
- Very Fast Uninterrupted transfer.
- Advanced Communication
- Microprocessor Control
- ECO FRIENDLY
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.
