The permitted output current I

ing following formula:

= Output rated current at 40 °C and up to 1000 m,
refer to ZElectr
ical data of the BM53XX– as from page 66.
If k

k
H
> 1, then I

,
an output current higher than I

is not possible.
NOTICE!
The following condition must always be met to prevent the device of overload:
