Intermediate DC bus circuit
handles the DC current.
•
Filter the intermediate DC circuit
voltage.
•
Prove mains transient protection.
•
Reduce RMS current.
•
Raise the power factor reflected
back to the line.
•
Reduce harmonics on the AC
input.
•
Stores the DC power.
•
Provides ride-through protection
for short power losses.
•
Converts the DC into a controlled
PWM AC waveform for a
controlled variable output to the
motor.
•
Regulated 3-phase output power
to the motor.

1.4.4 Enclosure Types and Power Ratings
For enclosure types and power ratings of the frequency
converters, refer to chapter 8.9 Power Ratings, Weight, and
Dimensions.

1.5 Approvals and Certifications

More approvals and certifications are available. Contact the
local Danfoss partner. Frequency converters of enclosure
type T7 (525–690 V) are UL certified for only 525–600 V.
The frequency converter complies with UL508C thermal
memory retention requirements. For more information,
refer to the section Motor Thermal Protection in the product
specific design guide.
