RCM150/300 Series 150/300 W DC-DC Converters The RCM Series converters are reliable power supplies for railway and transportation systems. There are 2 input voltage ranges covering all common railway batteries. The output delivers 150 or 300 W at 12, 15 or 24 V. The converters are designed for chassis mounting and exhibit a closed housing with cooling openings. Many options are available, such as an output ORing FET for redundant operation, output voltage adjustment, interruption time of 10 ms (class S2), shutdown input, and an output voltage monitor controlling a relay (change-over contact). Features RoHS lead-free-solder product 2 input voltage ranges, covering all railway batteries Single output 12, 15 or 24 V Closed housing for chassis mounting Extremely high efficiency and high power density Low inrush current 3 connectors: Input, output, auxiliary Overtemperature, overvoltage, overcurrent, and overload protection Many options available Dimensions: RCM150 96 x 36.1 x 164.5 mm (3.78 x 1.42 x 6.48 in) RCM300 116 x 38 x 188.6 mm (4.57 x 1.5 x 4.43 in) Compliant to EN 50155, EN 50121-3-2, AREMA Fire and smoke: compliant to EN 45545 and NFPA 130 5 year warranty Safety-approved to the latest edition of IEC/EN 62368-1 and UL/CSA 62368-1 1 1 pending Table of Contents Description........................................................................................1 Electromagnetic Compatibility (EMC) .............................................12 Model Selection ................................................................................2 Immunity to Environmental Conditions ...........................................14 Functional Description ......................................................................3 Mechanical Data .............................................................................15 Electrical Input Data .........................................................................4 Safety and Installation Instructions .................................................16 Electrical Output Data.......................................................................7 Accessories ....................................................................................18 Description of Options ......................................................................9 belfuse.com/power-solutions BCD.00791 Rev.
