Conforming to SEMI F47 Voltage Sag Tolerance

Power supplies used in semiconductor manufacturing equipment are generally required to conform to the SEMI F47-0706 voltage sag tolerance standard. These standard details the conditions under which a power supply must continue to operate in the event of a temporary degradation of its single-phase AC input voltage level. (SEMI F47 does not apply to three-phase input power supplies.)
