Total power with internal forced air cooling is 400W including 12V/1A for Fan output and 5V/2A standby and 12V 8A. 2. The 24V output current shall be derated as a function of 12V current where 24V load <15.7 (12V Load / 1.86) amps. Ex. 24V max current = 11.4A when 12V is loaded to 8 amps. 3. Efficiency Values listed are measured at 115Vac input, full load and 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 for a minimum of 20 seconds. This will allow the output to resume normal cooperation. 6. No Output adjustment for 12V output. The 12V output shares the common return with the 24V output. 7. MTBF values are in hours, per Telcordia 332, Issue 6, 25C, full rated load (w/ airflow) at 110Vac input. 8. Tolerance 3% measured at 50% centering total regulation includes line, load, and initial setting. 9. 12V main output rise time delayed by 15ms after 24V turn-on.
