Product Descriptions

SmartPower Source Transfer Switch (STS), also known as the Redundant switch or Automatic Transfer Switch (ATS) or Static Transfer Switch (STS), is a high availability switch that has two input power sources for each AC line, which provide a redundancy electrical power for equipment. The power source of STS can be from the same or different source of transformers. The STS is designed to supply an electric power for equipments from a primary source and once the primary source is outage, then the STS will automatically transfer an output power supply to the secondary source. The transfer time during the power source transfered is limited within the standard of the safty factor range and the switching occurs safely between the two input sources regardless of any phase differences. The STS unit have provided network connectivity (as optional), which allows for remote management through Web, SNMP or Telnet interfaces.

Robust & Reliability out-of-phase switching
SmartPower STS is designed to provide redundancy as close as possible to the equipment, The STS deploys a “Break Before Make” technology based on relays to prevent relay welding, so there is no cross-connection of sources, regardless of the phase between sources. In an event of a short-circuit, the STS ensures that the fault could not affect an alternative source, therefore you can ensure to have a fault-free power source.
