The STS is designed to guarantee the uninterrupted operation of sensitive equipment. It is powered by two independent power sources and automatically makes a rapid switch from one source to the other when the original power supllying to its connected load fails. The user can know the power flow and STS's status from the front panel's LED indicators and monitor the STS via the built-in InsightPower SNMP IPv6 card. The unit has a network interface for the user to read and write parameters and the network interface can be implemented via the Ethernet protocol through and RJ45 connector. The STS is designed to be efficient and reliable.
