¹⁾ Extra power, short-term performance (up to typ. 4 s)

The power supply is designed to support loads with higher short-term power requirements without damage or shutdown.
The short-time duration/bonus time is controlled in hardware by an output power manager.
Extra power is available repeatedly. Detailed information can be found in the chapter on Repeated pulse load. If the power supply is subjected to extra power for longer than shown in the bonus time diagram (see Fig. Bonus time over output power), the maximum output power is automatically reduced to 480 W.

²⁾ The discharge current of the output capacitors is not taken into account.

Output 1: — Output voltage over output current

Output 2: — Bonus time over output power; Extra power recovery time

Extra power is available as soon as the power is turned on and after an output short-circuit or output overload.

Output 3: — Extra power after switching on; extra power after short circuit or overload
