2. Range of Applications
2.2. Power ratings of the TVD 1.3
The TVD 1.3 is available with a DC bus continuous power of 7.5 kW and 15
kW. It can be combined with an auxiliary bleeder module. This means that the
power supply can be optimally matched to the requirements of the respective
application.

Power ratings in the TVD 1.3
2.3. Overload Capabilities of the TVD 1.3
The TVD 1.3 can be overloaded for a short duration for the purpose of
accelerating feed and spindle drives.
The maximum acceleration ratings must be taken into account
during project planning and may not be exceeded!
