Resistors

MicroelettricaHeine has more than 100 years of experiences in design and manufacturing of Power Resistors for the most demanding applications.

We focus on customised solutions and the precise implementation of your requirements, based on our product ranges of aluminium resistors, wirewound resistors, plate resistors, band resistors, load banks and neutral earthing resistors. Therefore, we are using a compact and modular design to be most cost-efficient.

Among other applications our power resistors are widely used in industrial applications such as automation, in the infrastructure sector or in rail vehicle applications. Our resistors are available from 50W to the multiple MW range. For relevant applications, resistors with UL certification are available.
