The device has a power reserve of 20% included, which may even be used continuously at temperatures up to +45°C.

Additionally, it can deliver about 3 times the nominal output current for 12ms which helps to trip fuses on faulty

output branches or to start peak current demanding loads. Solenoids, contactors and pneumatic modules often have a

steady state coil and a pick-up coil. The inrush current demand of the pick-up coil is several times higher than the

steady-state current and usually exceeds the nominal output current (including the PowerBoost). The same situation

applies when starting a capacitive load.

The following examples show typical voltage dips:
