Forced Air Cooling

Forced air cooling of 300 LFM is required if the

internal fan is not specified. Cooling air velocity is

measured at the output exiting window (2.5” x 5”).

Airflow direction is from the input section to the

output section.

Isolation Diodes

Add “D” as a suffix to the model number to order factory installed

isolation diodes for parallel or redundant operation. For 24V models

with the “D” option, external caps are required to meet the 1%

noise/ripple spec. Power Good has a pull-up resistor of 475 on the

24V models. See Application Note #P1 for details.

N/A

Fan

Add “F” as a suffix to the model number to order integral fan.

Fan provides the required 300 LFM of forced air cooling, or

otherwise provided by the end user.
