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. The BonusPower
®
is
repeatedly available. Detailed information can be found in chapter 27.1 .
Once BonusPower
®
has been stopped by the output power limiter, a timer disables the next BonusPower
®
capability.
The recovery timer will start as soon as the output voltage reaches the adjusted value again, which usually happens
after the load has been reduced.

Peak current capability (up to several ms)
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 27.2.
