E314885 ## DESCRIPTION The compact versatile, industrial + household + medical grade AC/DC converter series RACM40-K delivers 40 watts of output power from -40°C to +60°C with natural air convection only, and up to +85°C with derating or forced air cooling. With a clear focus on extended thermal performance for systems where space is limited, these 1.6“ x 3.1“ compact modules are designed to gain highest overall efficiency levels over the full output load range from universal AC inputs. The RACM40-K/OF has ANSI/AAMI/IEC 60601-1 medical safety and EN 60601-1-2 medical EMC certifications, 2MOPP, 4kVac/1min isolation and offers OVC III certified to IEC61558. It is additionally certified (CB Report) IEC/EN 62368-1; IEC61010 and IEC61558-1/-2-16 for industrial applications and IEC/EN 60335-1 for household appliances. The robust built-in class B EMC filter has sufficient margin to allow either Class II or Class I PELV with grounded output installations. A range of mechanical fixing options makes the RACM40-K suitable for many different mounting conditions: the standard chassis-mount part mates with Molex connectors, and the /PCB option permits direct installation in printed circuit boards. Additionally, a 2“ x 3.1“ footprint for backward-compatibility retrofit for legacy designs is available on request. ## SELECTION GUIDE |SELECTION GUIDE||||||| |---|---|---|---|---|---|---| |Part||Operating Input|Output Voltage|Output|Efficiency|Output Power| |Number||Range(4, 5)|nom.|Current nom.|typ.(1)|continuous| |||[VAC]|[VDC]|[mA]|[%]|[W]| |RACM40-05SK/OF(2, 3)|(2, 3)|80-264|5|6000|87|30| |RACM40-12SK/OF(2, 3)|(2, 3)|80-264|12|3334|90|40| |RACM40-15SK/OF(2, 3)|(2, 3)|80-264|15|2667|90|40| |RACM40-18SK/OF(2, 3)|(2, 3)|80-264|18|2222|90|40| |RACM40-24SK/OF(2, 3)|(2, 3)|80-264|24|1667|90|40| |RACM40-36SK/OF(2, 3)|(2, 3)|80-264|36|1111|90|40| |RACM40-48SK/OF(2, 3)|(2, 3)|80-264|48|833|90|40| Note1: Efficiency is tested at +25°C with constant resistant mode at full load and 230VAC copyright © RECOM Power GmbH, all rights reserved www.recom-power.com Rev. 2-2024 Page 1 Technical Data Sheet RACM40-K/OF Series ◊ AC/DC Power Supply 40W ◊ Input: 100V-240VAC **AC/DC Converter** MODEL NUMBERING ## - RACM40- __ SK /OF/___ ___ rated Output Power Packaging options[(3)] Output Voltage Connection options[(2)] **S** ingle Note2: “/OF” = standard 1.6”x3.1” open frame version with standard header connectors “/OF/PCB” = 1.6”x3.1” open frame with PCB mounting pins - “OF/2x3” = 2”x3.1” open frame version with standard header connector (12 and 24Vout versions available; 5,15,18,36 and 48Vout versions with MOQ ≥1000pcs) - Note3: without suffix, standard single pack (1pcs/cardboard box) add suffix “-CTN” for project packaging (4 layers of tray within a carton, for “/OF” only + MOQ ≥1008pcs) with suffix “-T” = single layer tray packing (available for OF/PCB models) for detail information, refer to „PACKAGING INFORMATION“ For other case/connection/footprint options, please contact RECOM technical support ## Ordering Examples: RACM40-05SK/OF 5Vout 1.6” x 3.1” standard header connector 1pcs/cardboard box RACM40-24SK/OF/PCB-T 24Vout 1.6” x 3.1” PCB mounting pins 16pcs/tray packaging RACM40-12SK/OF/2x3 12Vout 2” x 3.1” standard header connector 1pcs/cardboard box RACM40-12SK/OF-CTN 12Vout 1.6” x 3.1” standard header connector 48pcs/carton (MOQ= 1008pcs) |BASIC CHARACTERISTICS (measured @|TAMB= 25°C, nom.
