Selenium Rectifier
The H and W series are the result of continuous research and development programme aimed at reliable, low-cost, 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 rectifier elements are manufactured by an improved, closely controlled vaccum deposition process. This new process ensure stable, non- ageing, low loss characteristics permitting higher current density operation while maintaining a reliability standard which has been a by in the selenium rectifier field for over thirty years.
IRI selenium rectifier ’s elements are available in two categories, series H & w. Both series are available in Voltage grades up to 36 volts.
