Country: Spain · Model: SPS ATS / STS
The SPS ATS / STS automatic transfer switch of 16 or 32 A holds a single-phase critical load between two independent power lines. A typical scheme is two UPS units feeding one rack with servers or telecom equipment that has a single power supply.

Description
The device acts as an automatic transfer of reserve in a single-phase circuit. When the main line disappears or goes outside the permissible limits, the load is moved to the backup line without staff involvement. Switching can also be done manually, for example before servicing one of the UPS units, to take it out of operation without stopping the consumers. For monitoring there are USB and RS-232, an emergency shutdown input EPO and dry contacts for passing the status to a dispatching system. An optional SNMP card brings the switch into the monitoring network together with other server room equipment, so the operator sees which line is feeding the rack at the moment.
How to choose
The choice comes down to the rated current. The 16 A version is designed for circuits with lower total consumption, and the 32 A is taken for a denser rack or a group of cabinets. The total current of all consumers behind the switch must fit within the rating with a margin, and both sources must be single-phase. If integration into network monitoring is needed, the SNMP option is ordered at once.

FAQ
What is the rated current of the SPS ATS / STS switches?
The devices are made for 16 A and for 32 A. Both versions work with single-phase power lines.
Can one load be fed from two UPS units through the SPS ATS?
Yes, the switch is made for this. It selects one of two single-phase lines, for example two UPS units, and moves the load to the backup one automatically or on an operator command.
What communication interfaces does the SPS STS have?
As standard there are USB, RS-232, an EPO input and dry contacts. The SNMP module is installed optionally for work in a monitoring network.
Is the SPS ATS suitable for a three-phase load?
No, the specification states switching between two single-phase lines. Three-phase consumers are not connected through this switch.
