Protection
Over temperature
Protection type: shut down o/p voltage recovers automatically after temperature goes down
Short circuit
Hiccup mode, it will recover automatically after fault condition is removed
Open circuit
Protection type: shut down O/P voltage and lock; then power on again, if there is no fault ,
work again
