Soft Starter Module Benefits

Semikron’s SEMiSTART are power modules integrated with heat sinks, the provide an ultra-compact design for soft-start applications. They feature double-sided cooling along with pressure contact technology allowing for a high current capability with overload currents of up to 3080A for 20s overload duration. SEMiSTART is a robust plug and play subsystem that helps reduce development time and system costs.



Semikron’s SEMiSTART range of anti-parallel thyristor modules are designed for soft-start applications.


GD Rectifiers first started distributing Semikron’s semiconductors (including diodes, IGBTs, MOSFETs, thyristors, thyristor diode modules and rectifiers), heat sinks and power assemblies in 1964. With over 50 years’ experience in the power electronics industry, GD Rectifiers are one of the UK’s leading Semikron distributors, offering unrivalled high pricing, fast delivery and customer service.
