The Alpha range resistors from Danotherm consist of fully welded wirewound resistors, mounted in silica sand, insulated with Micanite and mounted in an anodised aluminium housing. The base material is high temperature Micanite which is long time stable at +700°C and short time resistant up to +1000°C. The construction has high resistance to temperature changes. These braking resistors comply with IP50 giving electrical and thermal protection. Danotherm has developed thermal simulation corresponding to all resistor types and resistor values. By using these models, Danotherm were able to calculate the temperature rises in the resistor wire and on the surface for all possible load applications.
Danotherm CBR-H resistors are ideal for applications in electronic variable speed drives as braking resistors. This allows you to control the speed or position of escalators, elevators, conveyor belts and cranes where regenerated energy requires dissipation. They are also suitable for renewable energy systems such as kite power, solar inverters, solar power, tidal power and wind turbines.
