What is Hiccup Mode / Hiccup Protection?

Hi, Welcome to Tech Forum. The Hiccup mode, recovers automatically after fault condition is removed for the load protection. But the LRS-150 still lists voltage overload as protection mode and will shut down o/p voltage, re-power on to recovery, would need to be restarted. The Hiccup mode is only listed on the overload, not the voltage load. Both of these would have the same Voltage Overload restart.
