For the use of HCS03 converters in regenerative operation, we offer a selection of particularly compact brake resistors for various different levels of power consumption. The brake resistor is mounted directly above the converter. This space-saving arrangement also simplifies the installation work. At the same time, the converter’s extracted air flow makes an effective cooling system. The robust construction and high dielectric strength of the resistor elements enable extreme pulse loading. The resistor elements are flameproof and are protected from harmful environmental factors by their full encapsulation.
