Mini DC-DC Voltage Step-down Regulator Module 3V-40VDCDCSDM
Input:DC3V to 40V (iutput voltage must be 1.5V higher than onput voltage of 1.5V, step-up is disabled)
Output: DC 1.5V to 35V continuously adjustable.
Maximum current output: 3A.
Features:Adopting SANYO solid CAP, High Q value power inductors With output LED indicator.
SIZE: 45(L)*20(W)*14(H)mm£¨with potentiometer£©DC-DC
Note: If you want to use it for a long time,the current should be under 2.5a.
For the stable output,please make sure the differential pressure under 1.5v, when you regulate the output voltage,youd better work it with multimeter.
