Total power with 200lfm of forced air cooling is 425W (385W for 12V model) including 12V/1A for Fan output and 5V/2A standby.
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.
Efficiency values listed are typical and are measured at 115Vac input, full load output current, at an ambient temperature of 25°C.
Measured at 25°C ambient with noise probe directly at end of 6” twisted pair terminated with 0.1μF ceramic and 10μF low ESR capacitors. Values will be higher at ambient
temperatures below 0°C.
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.
No output adjustment for 56V model.
MTBF values are in hours, per Telcordia 332, Issue 6, 25°C, full rated load (w/airflow) at 110Vac input.
