Faster to the right solution
Identify the application. Find the right product.
01
Electric motors
Soft start for machines, tools and motor-driven loads.
02Transformers & power supplies
Limit load peaks, protect installations and plan restart readiness.
03Speed control
Control and regulate AC motors with robust electronics.
04Custom solution
When standard products are not enough, the right electronics are developed.
Power, tamed
When inrush currents must stay under control.
When electric motors, transformers and electronic loads are switched on, currents can occur that reach several times the nominal current. GEFI limits these load peaks, reduces failures and protects machines, tools and installations.
Engineering flow
From load peak to production-ready solution.
Good electronics are not built from show effects, but from precise engineering judgment: understand the application, clarify electrical limits, select a product or design a custom solution.
