Power Dissipation

Power Dissipation of Power Section

The power dissipation of a drive system radiated to the control cabinet is
calculated from the sum of the power dissipation of the supply unit, the
power dissipation of the mains connecting unit, the power dissipation of
each drive controller, and the power dissipation of additional units (e.g.
DC bus resistor unit or DC bus capacitor unit).
To determine the power dissipation of the supply unit, the mains
connecting unit, and
corresponding documentation of these units.
The power dissipation of a drive controller is composed of
• power dissipation of optional modules
• power dissipation of control section
• basic power dissipation of power section
• current-related power dissipation of power section
See page 7-10 for information on power consumption due to the 24 V
control voltage.
The level of power dissipation occurring in power sections can be
ascertained from the diagrams contained in page 6-16 onwards. In the
diagrams basic and current-related power dissipation are summarized.
