BonusPower, short term power capability (up to typ. 4s)
The power supply is designed to support loads with a higher short-term power requirement without damage or shutdown. The short-
term duration is hardware controlled by an output power manager. BonusPower is repeatedly available. Detailed information
can be found in section 25.1. If the power supply is loaded longer with the BonusPower than shown in the bonus-time diagram (see
Fig. 6-3), the max. output power is automatically reduced to 960W.
**)
Discharge current of output capacitors is not included.
***)
This is the maximum output voltage which can occur at the clockwise end position of the potentiometer due to tolerances. It is not
guaranteed value which can be achieved. The typical value is about 55V.
