REO has been manufacturing resistors for more than 75 years. Its wide experience and application knowledge of high-capacity braking resistors that are wound on tubes or ceramic cores has led it to develop more modern technologies. The Kyritz subsidary has been producing braking resistors in profile construction for more than 20 years. Better heat dissipation and better dynamic behaviour of the resistors have been achieved by filling heat conducting material surrounding the wound body. Impressive temperature reductions are possible due to efficient power dissipation.
REO can provide resistors for inverters that can offer the following advantages:
REO's aim is to always integrate new technologies in development of its resistor range, especially with regard to the dimensions, heat evolution, dynamic behaviour and not least, design and layout. Moreover, innovations are promoted and the technological compositions of various new products are presented to the market in the form of systems, such as, e.g. from these developments emerged the series of REOHM resistors BW 150 in 9 different versions for:
REO resistors are typically used in conjunction with brake choppers, which are either located in frequency converters, or – particularly with large systems, are present as stand-alone units - braking resistors are connected and disconnected and thus consume the excess voltage at the capacitors of the DC intermediate circuit. Together with the braking resistors, REO will also supply you the corresponding brake chopper or resistors with integrated brake chopper.
