NOTE:

a

Average input energy (E) is calculated by the below formula.
E = 1/2 CV
V: Main discharge voltage (V dc)

b

Average Input(W) is calculated by the below formula.
W = E × f f: Repetition frequency (repetition rate)

c

At 1 J/flash (60 W) input. Maximum 100 Hz operation is possible with keeping average input 60 W or lower.

d

At 1 J/flash input energy (60 W) with using the cooling jacket of E6611.

e

It is necessary to have an additional external capacitor E7289-01 for 60 W input, when 1 J/flash input energy is needed.

f

It has to be used for the operation more than 15 W input.
