LRS Series - Subrack Systems MK007

Share

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.

Specifications

  • Compliant to AREMA, EN 50155, and EN 50121-4
  • 19-inch DIN-rack system, convection cooling
  • Wide input voltage range 85 to 264 VAC, 50 to 60 Hz
  • Power factor >0.93, harmonics IEC/EN 61000-3-2

Features

  • Extremely high isolation of all output circuits
  • Excellent surge and transient protection
  • Active output current sharing
  • Output voltage monitor with relay contacts
  • Inrush current limitation
  • Hot swappable
