Slip rings can be used in any electromechanical system that requires unrestrained, continuous rotation while transferring power or data from a stationary to a rotating structure. High-current slip ring series are characterized by higher current, adopt specific design and advance technology to meet different application requirements. At present, this series we produced could be up to 800 amperes current. Please let me know your requirements, we will provide the best solution for you. The JSR-BC060-3P200-15S provides 2 Circuits 400VDC 200A , and 15 circuits 24V 2A control signal .The Slip ring assemblies use carbon conduction , IP66 protection is optional .
