Beginning with the continuous current (both axes combined) rating of the drive, use the curve for the +HV
voltage to find the power dissipation. The vertical dashed lines show the continuous current ratings of the three
BE2/BP2 models. Example: A BE2-090-20 is operating at 65 Vdc. Power dissipation is ~22.5 W.

ISSIPATION
Using the power dissipation from the chart above, draw a vertical line from that number on the X-axis upwards
in the chart below. The intersection of this line and the curves now shows the maximum ambient temperature
that is allowed for the four mounting/cooling options.
Example: at 22.5W the maximum ambient temperature with a Heatsink and No Fan (HSNF) is 41C.
