722 PLANNING ELECTRICAL INSTALLATIONS EVEN BETTER You will certainly notice the new technical data when browsing through our power supplies and ask yourself what it is all about? In future, we would like to support you even better in the planning and dimensioning of your installations. The background to this is that more and more power supplies for lighting are already being installed in standard buildings [directly in the luminaires or as an external power supply]. Due to the inrush currents inherent in the design, e.g. after a power failure and the subsequent simultaneous start of all power supplies, an overload of the circuit breakers may occur. In order to be able to take this into account during the planning stage, we provide you with the necessary data for all our power supplies. In future, you will find the specification of the maximum inrush current directly with our power supply units. The maximum current value [amperes/A], is specified in connection with the respective time [microseconds/µs] and defines when exactly the highest current consumption occurs after the mains voltage is applied. You will find this limit value again with many manufacturers in the data sheets of corresponding components, as this can lead to an overload/ damage.

In our quick finders you will find the number for the most common types of circuit breaker [B10A, B16A, C10A, C16A]. HOW MANY POWER SUPPLY UNITS PER CIRCUIT BREAKER? Due to their design, power supplies sometimes represent very different capacitive loads. Especially in combination with motion detectors, twilight switches or switching/dimming actuators, this value [as with the capacitor in nF/pF], which is available for many power supplies and specified in our quick finders, plays an important role with regard to the suitability and durability of all components. Please also refer to the manufacturer's data sheets.
