The Riello MASTER SWITCH 100-600A from Value Power Systems is a static transfer switch range commonly associated with power continuity applications to improve resilience. The system can be used in conjunction with UPS or as separate standalone devices. Used effectively the desirable 5 9's of reliability can be achieved
The Master switch adds a source of redundancy to a critical installation and automatically transfers the connected load between two separate AC power sources. The transfer can be automatic when an input power supply fails outside set tolerances or be manually forced using the front panel keypad or remotely via a communications network.
In the event that one of the two power sources does not return to the accepted tolerance values, the MASTERSWITCH will transfer the other loads over to the second power source (this happens instantly if the two sources are in phase). This can help prevent power interruption to critical loads
In the event of overloads and load faults. In the event of an overload or fault condition, the internal protection system within the STS device can be configured to disconnect power at defined levels. In the extreme situation of a downstream short circuit Master Switch can disconnect the load to prevent disruption.
The Riello Master Switch has double redundant ventilation called “fan redundancy plus”. Thanks to this function, in the remote possibility that two fans both fail at the same time, the others would still be able to dissipate the heat generated at nominal load. The fans can be hot swapped so as to ensure no break in system operation during the repair.
