*) 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 with the BonusPower longer than shown in the Bonus-time diagram (see
Fig. 6-5), the max. output power is automatically reduced to 960W. If the power requirement is continuously above 960W and the
voltage falls below approx. 40V (due to the current regulating mode at overload), the unit shuts-off and makes periodical restart
attempts. This behavior is called hiccup mode which is described below. If the voltage is above 40V, the unit continuously delivers
current.
**) Hiccup PLUS Mode
Up to 4s of overloading, the power supply delivers continuous output current. After this, the output power is reduced to nearly zero
for approx. 17s before a new start attempt is automatically performed. If the overload has been cleared, the device will operate
normally. If the overload still exists, the output current will be delivered for 2 to 4s (depending on the overload) again followed by a
17s rest time. This cycle is repeated as long as the overload exists. See Fig. 6-3. During the off-period a small rest voltage and rest
current is present on the output.
***) 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. There is
no guarantee this value can be achieved. The typical value is about 55V.
