Output voltage does not exceed Input voltage. This is buck board, not boost board.
Output short-circuit protection
Adjust pipe security protection
Overcurrent, overheating protection
DC input voltage: 5-35V
AC input voltage: 6-24V
Output voltage: 1.25V-37V adjustable
Output current: 1A

Since the within LM317 is linear voltage regulator, power consumption are high. When the input voltage-different high, the output current will also be high, notice that the consumption should not be too high. In the normal condition the consumption dont over 20W. So recommend classification regulator voltage.
