5-15. Output peak Current
For model with output peak current, please meet the following condition.
Reduce peak current value according to output derating as section 6-1.
The output is shut down by protection circuit when rated current and continuous peak output time (τ) exceeds rated
value during usage.
When protection circuit is activated, input is temporarily cut off for a few minutes and then power is re-input or
remote ON/OFF control signal should be input for recovery of the output.
