Description:

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 Power-Boost is repeatedly available. 

Detailed information can be found in chapter 27.1. If the power supply is loaded longer with the Power-Boost than shown in 

the Power-Boost time diagram (see Fig 8-2), the max. output power is automatically reduced to 480W. 

If the power requirement is continuously above 480W and the voltage falls below approx. 20V (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 20V, the unit continuously delivers current. 

Hiccup 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 a17 s rest time. This cycle is repeated as long as the overload exists. See Fig. 8-3. During the 

off-period a small rest voltage and rest current is present on the output.
