Safe attachment brake resistor

At this year's Hannover Messe, Michael Koch GmbH is presenting a new safe braking resistor for mounting on control cabinets.

At this year's Hannover Messe, Michael Koch GmbH is presenting a new, safe braking resistor for mounting on control cabinets. The resistor's footprint, measuring 550 x 440 mm, fits directly onto the roof of standard control cabinets. Continuous power can range in 400-watt increments up to 8 kilowatts, which, at 35 times the braking power at one percent duty cycle and a 120-second cycle time, corresponds to a peak power of 280 kilowatts for 1.2 seconds. The resistance values range from less than one to several thousand ohms, allowing for a highly flexible adaptation to the electrical requirements of the drive and its braking transistor. The supply cable is designed according to customer requirements. Its thickness and length are determined according to the application and can be sheathed for mechanical protection. The supply cable is connected in a spacious terminal box. Overall, a high degree of protection is achieved, making it suitable for use even in harsh environments. The safe add-on braking resistor can be equipped with a suitable touch guard, which brings it to a height of 275 mm. Without it, it is 252.5 mm high. Additional mechanical covers are also possible, allowing the safe braking resistor to be individually adapted to the ambient conditions.
