Delcon produces solid state relays which operate with energy principle. Reliable galvanic isolation is made by means of the pulse transformer. The high quality of the products is made by the good design, the choice of right components and good workmanship. The function is safeguarded by double functionality tests and 4.3 kV dielectric strenght test between them.

Due to effective sub-supplier network the company has remained small and flexible. The Delcon customers are typically leading companies in their field.

Delcon is situated near Helsinki in Nummela, where the development, final assembly and testing takes place. Sales is done by professional distributors.
