ELEMENTS & STACKS , W & H SERIES

The H and W series are the result of continuous research and development programme aimed at reliable , lowcost , compact selenium rectifier elements and stacks . High standard of quality are further insured by Westing house plants & machinery and the expert technical know how available at Insel Rectifiers

The aluminium based selenium rectifiers elements are manufactured by an improved , closely controlled vaccum deposition process . This new process ensure stable , non- agening , low loss chacractristics permitting highr current density operation while maintaining a reliability standard which has been a by in the selenium rectifiers field for over thirty years .

IRI selenium rectifiers elements are available in two categories , series H & w . Both series are available in Voltage grades upto 36 volts
