*) Extra Power, 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. This Extra Power is repeatedly available. Detailed information can be found in chapter “Repetitive pulse loading”. If the power supply is loaded longer with the Extra Power than shown in the bonus-time diagram (see Fig. “Bonus time vs. output power”), 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 28.5V.

Output 1: — Output voltage vs. output current in “single use” mode, typ.;
Output voltage vs. output current in “parallel use” mode, typ.

Output 2: — Bonus time vs. output power;
Dynamic overcurrent capability, typ.

The Extra Power is available as soon as power comes on and after the end of an output short circuit or output overload.

Output 4: — BonusPower after input turn-on; BonusPower after output short
