Ensuring a constant power supply is critical in typical change-over switch applications Use in critical applications The most typical application for changeover switches is utility and stand-by generating set applications where change-over switches commutate between two sources. Often the back-up power source is a stand-by generator set. These generator sets (Gen-sets) are a fundamental part of many Critical Power applications where a constant and reliable source of electrical energy is required. Ensuring back-up power Change-over switches are used to switch from the grid to the back-up in case...
