Single-phase3U Rackmount 63-125A static transfer switch  Uninterruptible power supply airport  data center 
The STS product is designed with two independent power inlets to supply power to the load from a primary power source.
The transfer time from one line to another is seamless to the connected equipment. Afterswitching to a secondary power source,
the STS can also switch power back to the primary input when power to the primary input is restored.Should primary power source fail,
the secondary will automatically back up the connected equipment without any interruption.
STS static transfer switch is mainly used for two-way power supply switching, for the power supply two-choice automatic switching system. Under normal working condition, the load is always connected to the main power supply when the main power supply is in normal voltage range. When the main power supply fails, the load is automatically switched to the backup power supply, and after the main power supply returns to normal, the load is automatically switched to the main power supply.
