Efficiency hits 97.5%, meaning less heat in the cabinet and more power to the load — a real advantage in a sealed panel where every watt of waste heat needs to be managed. The output voltage follows the formula Vin minus approximately 0.6 V, so it's a tracking regulator, not a fixed boost or buck; plan your input rail accordingly. The 45 mm wide enclosure fits tightly in a crowded panel row. Push-in terminals accept 0.75-16 mm² at input and output, so no ferrule crimping for stranded wire up to that size. The 40 A rated output at 24 V DC is the continuous current the converter can supply under the listed conditions (rated input, +25 °C ambient). That's enough for a multi-axis DC motor bank or a dense 24 V control bus. The IP20 protection means it's for dry indoor cabinets only — no washdown zones. Operating range of -30 to +70 °C with natural convection covers most machine rooms and outdoor cabinets in temperate climates; no forced cooling required. Clearance: 45 mm top and bottom, 0 mm left and right — you can butt multiple units side-by-side without derating spacing. That's a space-saving layout for high-density panels. MTBF at 40 °C is 6,100,000 hours — roughly 700 years mean time between failures under that thermal condition. For a BOM freeze, that number supports a long service interval with no scheduled replacement. CE marked. UL/cULus listed under UL 508 and CSA C22.2 No. 107.1, File E197259 — so it's accepted for US and Canadian industrial control panels. Also CSA C22.2 No. 62368-1. EMC compliance covers EN 61000-6-3 (emissions) and EN 61000-6-2 (immunity), which is the standard for industrial environments. No ATEX, IECEx, or Class 1 Division 2 rating — not for hazardous locations.","metaTitle":"6EP4347-7RB00-0AX0 DC-DC Converter, 40 A, 24 V Output, DIN R","metaDescription":"Siemens 6EP4347-7RB00-0AX0 DC-DC converter, 40 A rated, 24 V DC output, 97.5% efficiency.
