SPS.16.STS: Redundancy in power supply sources
The Salicru SPS.16.STS is basically an automatic, single phase switch with two input AC lines, which uses two sine-wave power
supply sources to provide output voltage to load/s.
The SPS.16.STS is factory programmed with mains 1 as priority and mains 2 as reserve. Users can change this using the communication
software. Each time the SPS.16.STS is started, the system will start up with the criteria established the last time it was programmed.
It is possible to switch from mains 1 to mains 2 or vice versa using the BP2 pushbutton, and this change is recorded in the internal
memory. The power supply of the load/s is transfered from one mains to the other if the voltage and/or frequency of the priority source
is off-margins.
The LEDs on the control panel report the state of the equipment and operation at all times, and this panel is an easy-to-understand,
practical interface for any operator.
Performance
. Break Before Make.
. Automatic backfeed protection, as per standard EN 62310-1.
. Overloading and short-circuit protection in both mains (using
accessible fuses and 10A thermal relays).
. Redundant internal power supply (from mains 1 and 2).
. Alternating current detector (voltage and current detector).
. Output detector (current detector).
. Control panel with LED.
. Auxiliary contact for external RPO.
. IP30 protection index.
. The SPS.16.STS can transfer with P/N input wiring error.
. The two system inputs can be different phases of the same
three-phase N/R and N/S mains.
. Audible alarm silencer.
