automatic phase selector switch

PROTIME's APSS is micro controller based Automatic Phase Selector Switch used for Single phase Loads with Three Phase Input Supply. It is used for uninterrupted Supply to Single phase Load, when the phase form which the load is driven fails, it switch-over the load immediately to the other phase available in the 3-phase supply system. The unit also shifts the load even when voltage of the supplying phase goes out of U/V-O/V range (Settable-inside). Thus its useful for un-manned operations & saves the energy of alternate sources , when only 1 phase fails for load shedding or may be failure of fuse or any other cause. The connection is very simple with 3-phase input & 1 Phase output. It is available for Standard ratings of 6A, 16A, 32A & 63A.
