APABILITY

 

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. 

Branch circuits are often protected with circuit breakers or fuses. In case of a short or an overload in the branch 
circuit, the fuse needs a certain amount of over-current to trip or to blow. The peak current capability ensures the 
safe operation of subsequent circuit breakers. 

Assuming the input voltage is turned on before such an event, the built-in large sized output capacitors inside the 
power supply can deliver extra current. Discharging this capacitor causes a voltage dip on the output. The following 
two examples show typical voltage dips:
