Description Brand HilandOutput Voltage 0 30V AdjustableOutput Current 0 1A AdjustableInput voltage 24V AC Or DCPCB size 6 0 6 6CMWeight 47gThis is a simple easy to manufacture regulated power supply with current limit adjustment that limits the output current to a range of 0 1Aand provides an LED indication over the set output current Just follow the PCB marked to solder it will be OK without any debugging LM317 heat sink connect with PIN2 need to pay attention to the insulation between heat sink and circuit Transformer can use greater than 30W power the output voltage is 24V AC or 2 12V the center is idle You can also use DC input Adjust the V adj the output voltage can be continuously adjusted between 0 30V Adjust A adj can be set the maximum output current in 0 1A range When the output current exceeds the set current LED lights at this time adjust the V adj the voltage will not continue to increase to maintain the set current unchanged to ensure that the access to the circuit will not be damaged Note In the continuous output of the larger current please note that the temperature of 1N4007 and LM317 will be higher if you need a long time high current output it is recommended to replace 1N4007 as 1N5408 and do theheat dissipation for LM317 to ensure safety Package included 1 x DIY 0 30V 0 1A LM317 Adjustable Voltage Current Power Supply Kit Without Heatsink
