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.

Package included:

5 x 1.25V-37V AC/DC to DC LM317 adjustable voltage regulator
