RCM500/1000 Series 500/1000 W DC-DC Converters The RCM500 and RCM1000 Series converters are reliable power supplies for railway and transportation systems. They are optimized for 72 or 110 V railway batteries. The output delivers 24 V with 500 or 1000 W. 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, shutdown input, and a monitoring relay (change-over contact). Features Optimized for 72 V or 110 V railway batteries Output voltage 24 V Closed housing for chassis mounting Extremely high efficiency and high power density Low inrush current 3 connectors: Input, output, auxiliary (option) Overtemperature, overvoltage, overcurrent, and short-circuit protection Many options available Compliant to EN 50155, EN 50121-3-2, AREMA RoHS-compatible for all 6 substances 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) ............................................. 11 Model Selection ................................................................................2 Immunity to Environmental Conditions ...........................................13 Functional Description ......................................................................3 Mechanical Data .............................................................................14 Safety and Installation Instructions .................................................15 Electrical Input Data .........................................................................4 Electrical Output Data.......................................................................6 Accessories ....................................................................................17 Description of Options ......................................................................8 belfuse.com/power-solutions BCD.00803 Rev AG, 10-Jun-2021RCM Series 500 / 1000 W DC-DC Converters Model Selection Table 1: Standard models 2 Input voltage Output Power Efficiency Model Options 1 1 V V V V I P typ i min i cont i max o nom o nom o nom V V V V A W % 24 21 500 96 72RCM500-24 43.2 50.4 (72) 90 110 24 42 1000 96 72RCM1000-24 D, M, Q, F, K 24 21 500 96.4 110RCM500-24 66 77 (110) 137.5 154 24 42 1000 96.4 110RCM1000-24 1 Short time see table 2 for details. 2 Efficiency at T = 25 C, V I , V .
