1) BonusPower
®
, short term power capability (up to typ. 4s)
The DC/DC converter 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. This BonusPower
® is repeatedly available. Detailed
information can be found in chapter 21.1. If the DC/DC converter is loaded longer with the BonusPower
®
than shown in the bonus-
time diagram (see Fig. 5-3), the max. output power is automatically reduced to 480W.
2) Discharge current of output capacitors is not included.
3) 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 28.5V.
4) Reduce output current according to Fig. 5-2 for the extended input voltage ranges from 360-480Vdc and 840-900Vdc.
