Tipos-00

The range of standard HR conventional transformers goes from 2,5VA to 18VA, builded in primary for 125V and 220V. Them cover the wide range of classic transformers used in most of countries. In our standard range there are aviable the setups of simple, dual and center tapped secondaries for tensions from 4,5V to 24V.

Our assembly system and impregnation guarantees a mantaintment of the specifications of energy performance and funcionality what make outstand the HR transformer in the most reliable ones of this classic technology.
