12.7 Power Ratings
12.7.1 Overload Capability
The
low overload
means that if 110% of the continuous current (I
L
) is required for 1 minute every 10 minutes, the remaining 9 minutes
must be approximately 98% of I
L
or less. This is to make sure that the output current is not more than I
L
during the duty cycle.
