2-172 Watts Loss
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. Data for
other load/speed/PWM combinations can be determined using the
calculator on the PowerFlex e-Library.
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.
