OSB: 9115 SERIES OSM 9115 SERIES OSS 9115 SERIES N AMER PHILIPS/DISCRETE eSE D 6653931 0022884 ca 723-05 HIGH-VOLTAGE RECTIFIER STACKS The OSB9115, OSM9115 and OSS9115 series are ranges of high-voltage rectifier assemblies incorporating controlled avalanche diodes mounted on fire-proof triangular formers. They are supplied with M6 studs. The 0S89115 series is intended for application in two-phase half-wave rectifier circuits. The OSM9115 series is intended for application in single-phase or three-phase bridges or in voltage doubler circuits. The OSS9115 series is intended for all kinds of high-voltage rectification. The OSB9115 series and OSM9115 series are supplied with a centre tap (8-32UNC). The maximum crest working voltages of the OSB9115 and OSM9115 series cover the range from 3 kV to 27 kV, and of the OSS9115 series the range from 4.5 kV to 54 kV in 1.5kV steps.
