WESPACK Rectifier Diodes - Capsule Types WESTCODE Home
Introducing a new range of Rectifier Diodes using the innovative slimline WESPACK housing to provide devices with the maximum power rating for weight and volume without compromising on quality and reliability.
Two of the new devices are available in 38mm pole face diameter housings, and one in a 50mm pole face diameter housing, mounted in a low profile 14mm cold weld capsule. WESPACK Rectifier Diodes have a maximum voltage rating of 2.8kV or 3kV and will be available in the four outlines currently offered in our Phase Control Thyristor WESPACK range.
Typical applications include; input rectifiers and bridges, Welding, DC power supplies, chemical power supplies, battery charges, etc.
