The air-cooled thyristor rectifier (diode) bays are intended (SVP, SVPR, SVPD) to be used as part of power control channel in rectifiers for DC drives and industrial electric installations.
They can be designed either as reversible or non-reversible ones. Rated output current — 1000 – 4000 A. Rated output (DC) voltage — 115-1150 V.
