This read-write Integer32, ranging from 20000 to 50000, sets the load threshold at which all rectifiers in the Dc1 plant are brought online simultaneously, rather than sequencing them on gradually. An admin tunes this value to balance fast response to sudden load increases against efficiently running fewer rectifiers under light load. For example, setting this near the high end of the range would delay bringing all rectifiers on until load current climbs quite high, favoring energy efficiency under normal conditions.
