CUS400M 3"x5" Medical & Industrial Power Supplies

TDK Lambda CUS400M 3" x 5" x 1.55" Medical and Industrial Power Supplies deliver 400W output power with forced air or 250W output power when convection cooled with a 400W peak power for extended periods. Cooling is assisted via conduction through the base into the equipment chassis. With medical and ITE certifications, the units can be used in both Classes I and II (no ground wire) applications and meet Class B Conducted and Radiated EMI. Multiple case options are available.
