LRS Series
MK007 is a power supply system designed for railway and subway application. The applicable railway standards, mainly EN 50155, EN 50121-4, and the respective AREMA standards are observed. The power supply system is designed to accommodate special LK converters, for instance LK5542- 9ERD8TG or LK5662-9ERD8TG. A main feature is the enhanced voltage isolation (3000 VAC) between outputs, alarm signals, and the metallic chassis respectively the ground. The system consists of one or two racks. Each rack can accommodate up to 4 converters, which allows redundant configuration in terms of input and output energy. The power supply rack system supports also battery charging with temperature sensors controling the LK converters. A floating relay contact is available to monitor the function of each converter.
