Caledon Controls have been manufacturing thyristor stacks for OEM for many years, and the latest designs incorporate the benefits of considerable applications and design experience
The Company currently produce two standard ranges of thyristor stack for heating applications namely the Thyristor SCR series for resistive loads and the STA model for transformer coupled loads. These stacks have been specifically designed to meet the requirements of the European EMC and low voltage directives.
These Thyroid Stack incorporate many feature’s to ensure long term reliability. They are conservatively rated, with large heat sinks, and the full current rating is available up to fifty degrees Celsius at an ambient temperature. All stack units are protected against voltage spikes with snubbers and MOVs , and are fitted with integral semi conductor fuses for protection against short circuits. The cooling fans are fitted with long life ball bearings. In the event that replacement should become necessary, the printed circuit cards can be changed in a few minutes, and a straight forward mechanical design ensures that the isolated base thyristor modules can also be changed quickly in situ with a minimum of specialist knowledge.
