This kit provides a variable output power supply ranging from 1.2 to 15 Volt / 3 A. It uses Low Dropout Positive Regulator LM1084 in TO220 package for delivering variable output voltage.
Schematic
Output - variable output from 1.2 ~ 15 VOLT / 3 A Regulated low ripple DC voltage
Heatsink for regulator IC
On board bridge rectifier to convert AC to DC
LED indication at input of IC
Power Battery Terminal (PBT) for easy input and output connection
Zener trimmed band gap reference, current limiting and thermal shutdown (provided by IC feature)
Filter capacitors for low ripple DC output
Onboard PCB mounted Potentiometer (POT) for varying the output voltage
PCB dimensions 46 mm x 58 mm
Four mounting holes of 3.2 mm each
