IS 2511 : 1963 Specification for Polycrystalline Semi-conductor Rectifier Stacks

1 Scope

1.1 This standard applies to polycrystalline semi-conductorrectifier stacks and stack assembly used for supplying dc powerfrom ac sources at frequencies up to 2000 c/s.

1.2 This standard does not apply to telecommunication rectifiersother than those for power supplied to such apparatus, nor torectifiers used as auxiliaries to measuring instruments. Further,it does not include the main transformer or other associatedtransformers and apparatus, nor does it apply to rectifiers basedon mono-crystalline semi-conductor materials.
