  Output Short Circuit Protection

 Output short circuit behavior has no delay, retry and restart period of

 shutdown mechanism, but short circuit proof.

 After 2 seconds of short circuit, the DALI PSU output current is adjusted

 to less than 50ma,and the normal output can be automatically restored

 after the short circuit condition is  released.
