8 Technical data
8.1 Ratings
The continuous output current rating given is for a maximum ambient temperature of
40
°
C (104
°
F) and an altitude of 1000 m. For operation at higher temperatures and
altitudes derating is required.
Maximum continuous input current
The value of the maximum continuous input current is given to aid the selection of
cables and fuses. The value is stated for worst-case conditions.
