E = 1/2 CV2 E: Average input energy (J) C: Main discharge capacitor value (F) V: Main discharge voltage (V dc) Average Input(W) is calculated by the below formula. W = E × f f: Repetition frequency (repetition rate) At 1 J/flash (60 W) input. Maximum 100 Hz operation is possible with keeping average input 60 W or lower. At 1 J/flash input energy (60 W) with using the cooling jacket of E6611. It is necessary to have an additional external capacitor E7289-02 for 60 W input, when 1 J/flash input energy is needed. It has to be used for the operation more than 15 W input. Measured with supply voltage of 1000 V, main discharge capacitir of 2 µF and repetition rate of 10 Hz.
