*) 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. This BonusPower
®
is repeatedly available. Detailed information
can be found in chapter 24.1. If the power supply is loaded longer with the BonusPower
®
than shown in the Bonus-time diagram (see
Fig. 6-2), the max. output power is automatically reduced to 120/126W.
**) 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 28.6V.
Peak current capability (up to several milliseconds)
The power supply can deliver a peak current which is higher than the specified short term current. This helps to start
current demanding loads or to safely operate subsequent circuit breakers.
The extra current is supplied by the output capacitors inside the power supply. During this event, the capacitors will be
discharged and causes a voltage dip on the output. Detailed curves can be found in chapter 24.2.
Peak current voltage dips typ. from 24V to 20V at 10A for 50ms, resistive load
typ. from 24V to 20V at 20A for 2ms, resistive load
typ. from 24V to 16V at 20A for 5ms, resistive load
