APABILITY

 

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: 

 

Fig. 24-1

   Peak load with 2x the nominal 

current for 50ms, typ. 

 

Fig. 24-2

   60A Peak load for 12ms, typ. 

 

 

 

 

 

40A Peak load (resistive) for 50ms 
Output voltage dips from 24V to 16V. 

 

 

Please note: The DC-OK relay triggers when the voltage dips below 22Vdc for longer than 1ms.
