The RACM420-K series combines up to 550W peak power with advanced thermal management in a compact AC/DC power supply design. Its integrated thermally conductive baseplate enables efficient heat transfer to the application chassis, enhancing cooling performance particularly in fanless systems. Delivering 420W with forced-air cooling and up to 400W at high line or 250W at low line under natural convection, the series supports demanding industrial and medical applications. Based on a compact 3”×5” PCB footprint with additional mounting tabs, the series offers universal 85–264VAC input, -40°C to +80°C operation, OVC III rating, medical-grade 2MOPP isolation, and integrated EN55032 Class B filtering for easy system integration. Efficiency exceeding 90% from just 30W load and up to 300mW standby output power at less than 0.5W input consumption complete this versatile power solution.
