크기 = 110 x 76 x 15mm Overall Width = 76mm These dynamic braking resistors from Danotherm are insulated and can easily be mounted in compact constructions. The nominal load can be improved by forced air cooling or by mounting the resistors on a heat sink.For higher ohmic values, the resistor elements are wirewound on mica support sheets. Lower ohmic values are made with helix wound elements with ceramic support. The outer housing is an aluminium profile insulated with micanite sheets on all inner surfaces. The resistor elements are fixed symmetrically in the profile by the mica construction. This ensures a symmetric expansion of the resistors and maximum stability to high load impulses. The aluminium profile with the fixed resistor element is filled with quartz sand. This ensures a minimum change of the resistor surface temperature even if the resistor element reaches its maximum temperature during a pulse load.Small sizeOverload 10-16 x P nom (5 seconds pulse, 120 s cycle), depending on ohmic valueAluminium case ensures high IP ratingLow thermal drift of 100 ppm/K ensured by nickel-chrome 8020 alloyMica insulation ensures high dielectric strengthLow noise levelLow surface temperatureCapable of withstanding high vibrationFilled with Si02 for high-power overload capability and high thermal capacityThermal relief expansion mounting feetOptional thermal switch for thermal protection is availableFlying leadsFully insulated with no external live partsCCH resistors belong to Danotherms medium range of Alpha aluminium housed brake resistors. They are insulated, compact, and can easily be integrated in compact constructions. They are constructed for high pulse loads compared to the average load. CCH braking resistors comply with IP50, IP52 or IP65 giving electrical and thermal protection.Danotherm CCH 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.CCH brake resistors feature power rating options of 100 W to 1045 W. The flat construction of CCH series braking resistors also makes them suitable for heat sink cooling and they can be used in water-cooled equipment. Danotherm has developed thermal simulation for 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. This range is generally approved to UL 508 (E208678).
