CPFE1000FI Power Supplies TDK-Lambda CPFE1000FI Power Supplies are conduction-cooled units that offer 720W to 1000W output power. These modules feature an I2C interface in a compact size of 254mm x 112mm x 44mm. They have an input voltage of 90VAC to 265VAC and output voltages of 12V, 28V, and 48V. TDK-Lambda CPFE1000FI Power Supplies do not require a fan as they are baseplate cooled. Typical applications for the CPFE1000FI series include industrial, COTS, communications, LED, and broadcast.
