b) Pulsed Operation
For the calculation of the permissible pulse load Ptot-max the following formula is
applicable:
Ptot-max = Ptot-DC × Pulse Factor = Ptot-DC × (Ptot-max/Ptot-DC)
Use the values for Ptot-DC as derived from the above diagram and for the
Pulse Factor = Ptot-max/Ptot-DC from the following diagram to get a specific value.
