between the voltage across the capacitor s and the applied source voltage which are coupled together through the current limiting device makes it possible to limit the resulting current surge to an acceptable value subsequently the capacitors of the device can continue to be charged through a low impedance fully saturated current limiter the described embodiment permits higher currents and results in less losses throughout the balance of the charging cycle the above described embodiment is particularly advantageous in that it can be incorporated into a multi candela output device thus the benefits of multi candela devices continue to be available to customers who install them their visual output levels can continue to be set in the field either manually by the installer or if desired downloaded from a remote source one model thus can be used to meet a variety of output requirements thereby improving manufacturing efficiency and reducing inventory costs fig3 illustrates a basic form of a current limiting circuit 40 the circuit 40 includes a load capacitor 16 1 which is to be charged to a predetermined voltage capacitor 16 1 might for example correspond to the capacitor 16 of a strobe unit such as the unit 10 of fig1 merely coupling vsource to capacitor 16 1 as would be understood.
