Notes:
-DBRI-EW: Edge wound type (inductive)
-DBRI-HW: Heli-wire wound type (inductive)
-DBRI-VW: V-W grid type (non-inductive)
-The DBRO internal structure is the same as the DBRI
-The DBRO has a watertight external structure
-The Power rating is based on a 375C rise above an ambient of 40C
-Fan equipped models have different dimensions. (Check With RARA for details)
-Power increases of up to 100% are possible with some fan
equipped models with corresponding increases in dimensions. (Check with RARA for details)
