40W AC/DC PCB Mount Power Supply 48V/833mA

The ultra-compact versatile, industrial + household + medical grade AC/DC converter series RACM40-K and RACM40-K/OFdelivers 40 watts of output power from -40°C to +65°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" compact open card units and 1.8"x3.2" encapsulated modules are designed to gain highest overall efficiency levels over the full output load range from universal AC inputs. The RACM40-K and RACM40-K/OF have ANSI/ AAMI/IEC 60601-1 medical safety and EN 60601-1-2 medical EMC certifications and offers 4kVac/1 min isolation, 2MOPP, and is designed to meet B and BF requirements. It is additionally certified to IEC/ EN 62368-1 (CB Report) 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 open card /PCB mountable option permits direct installation in printed circuit boards without the need for additional standoffs. Additionally, a 2" x 3" footprint for backward-compatibility retrofit for legacy designs is available on request.

The mechanically rugged construction of the fully potted encapsulated RACM40-K module with 1,6mm pins and additional threaded inserts gives the series enhanced stability against shock and vibrations.
