Crydom offers many different technical resources such as the Heat Sink and Assembly Selector (top hyper link) that can help users choose the appropriate heat sink for their solid state relay. However, if designers choose to simplify the process of selecting a relay and corresponding accessories, then this tool can help select a solid state relay/heat sink ready-to-use assembly. If designers are still hesitant that a solid state switching solution could be the best decision, then Crydom invites one to try analyzing a specific case using the available Total Cost of Ownership Calculator (bottom hyper link). This calculator will help the designer quantify the benefits of having a switching solution with the advantages of solid state technology not only considering ones initial investment, but ones overall cost in the long run. To better understand the concepts used by the calculator Crydom suggests reading the available White Paper on the same topic.
