The Bwitt power supply STS series is designed to ensure that users can perform uninterrupted switching between two AC power supplies under the condition of dual UPS (se rua na ivurevure ni livaliva, kei na so tale.) me vakadeitaka na sega ni vakataotaki na kaukauwa ki na iyaya. The STS module is a redundant system composed of two completely independent power supplies. Na kena vakayagataki na STS power static transfer switch e dua na iwali rawarawa ka mana. Na module ni STS e tauyavutaka na noda kabani e vakayagataki me vakadeitaka na cakacaka sega ni vakataotaki ni nomu iyaya bibi. Vakayagataka na STS na tekinolaji vou ni kaukauwa kei na vakatulewa vakalivaliva torocake. It is mainly composed of intelligent control board and high-speed thyristor to provide users with the best solution. .

The static transfer switch is a dual-input transfer switch. Kena ivakarau, e dua na sala e semati ka sega ni semati na kena ikarua. E dua na UPS e solia na kaukauwa ki na iyaya. Ni leqa na UPS e solia e dua na sala, na STS e tagutuva vakatotolo na sala ni sema taumada, semata na sala sa tagutuvi taumada, ka semata na icolacola ki na dua tale na ivurevure ni livaliva.
