Surges up to 156 V for 2 s
With external input capacitor C i = 470 μF/200 V and option L
External Input Circuitry
The sum of the lengths of the supply lines to the source or to
the nearest capacitor ≥ 100 μ F (a + b) should not exceed 5 m,
unless option L is fitted. This option is recommended in order to
prevent power line oscillations and reduce superimposed
interference voltages.
