Total power with 200lfm of forced air cooling is 425W (385W for 12V model) including 12V/1A for Fan output and 5V/2A standby. 2. Maximum convection cooled power is limited to 280W for 12V model and 300W for other models. This includes 12V/0.5A fan output and 5V/2A standby output. 3. Efficiency values listed are typical and are measured at 115VAC input, full load output current, at an ambient temperature of 25C. 4. 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. 5. Fan Output: If the load on this output is other than a fan, a short circuit condition on this 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. 6. No output adjustment for 56V model. 7. MTBF values are in hours, per Telcordia 332, Issue 6, 25C, full rated load (w/airflow) at 110VAC input. TU425 Family Datasheet v1220 Copyright 2020 SL Power Electronics Corp. All rights reserved.
