500W AC/DC Supplies Need No Fans, Make No Noise

The CPFE500F baseplate-cooled ac/dc power supplies deliver up to 500W without the need for fan cooling. Operating temperature ranges from -40 to +85°C and the supplies come with a PCB protective coating to guard against moisture, dust, and other mal contaminants. Since there is no fan, the series suits low-noise applications such as audio mixing consoles and recording studios. These single output power supplies are available in 12V, 24V, 28V or 48 Vdc output versions with up to ±20% output voltage adjustment. Price for a 500W baseplate conduction-cooled CPFE500F model is $525 each/100. TDK-LAMBDA, San Diego, CA. (800) 526-2324.
