MASTER SWITCH is a static transfer switch commonly used within power continuity applications to improve resilience. The system can be used in conjunction with UPS or as separate standalone devices.
Master Switch guarantees a source of redundant power, allowing the load to
be switched between to alternative and independent power sources.
Switching can be automatic (when a supply source falls outside of acceptable
tolerances) or manually done by an operator from the front panel or remotely.
PROTECTION AGAINST POWER SUPPLY FAULTS
If one of the two power sources falls outside tolerance levels, Master Switch will transfer the consumers to the second power source (switching is instantaneous if the two sources are in phase).
PROTECTION AGAINST ENVIRONMENTAL DISTURBANCES
Overloads and load faults In the event of an overload, the user can
decide the level of intervention of the internal protection devices in order to block the power supply. In the extreme case of a downstream short circuit, Master Switch disconnects the load in order to avoid jeopardising the operation of the other loads (i.e. in the event of poor selectivity of
the protection devices).
