Total power with 200 LFM of forced air cooling is 425W (408W for 18V, 385W for 12V) including 12V/1A for fan output and 5V/2A standby. 2. Total convection power is 300W (280W for 12V model). Total power includes 5VSB and fan outputs. 3. Measured at 25C ambient with noise probe directly at end of 6 twisted pair terminated with 0.1F ceramic and 10F low ESR capacitors. Values will be higher at ambient temperatures below 0C. 4. Efficiency values listed are typical and are measured at 115VAC input, full load output current, at an ambient temperature of 25C. 5. Fan output regulation is with 1A min load on main output. 6. Fan output: If the load on the output is other than a fan, a short circuit condition on the output can only be remedied by removing both the cause of the short circuit and the load. This will allow the output to resume normal operation. MU425 Datasheet v0819 Copyright 2019 SL Power Electronics Corp. All rights reserved.
