Watts Loss 2-213
Watts Loss The following table lists watts loss data for PowerFlex drives running at full
load, full speed and a factory default PWM Frequency of 4 kHz.
PowerFlex 70
For PowerFlex 70 drives, Internal Watts are those dissipated by the control
structure of the drive and will be dissipated into the cabinet regardless of
mounting style. External Watts are those dissipated directly through the
heatsink and will be outside the cabinet for flange mount and inside the
cabinet for panel mount.

PowerFlex 700
PowerFlex 700 drives are offered in panel mount versions only. At this time,
no method exists for venting outside of a secondary enclosure. This requires
enclosure sizing for total watts. see Table 2.AD
