1.2 - 15V/3A variable and regulated PS

Posted on Aug 2, 2012

This kit provides a variable output power supply ranging from 1.2 to 15 V @ 3 A. It uses Low Dropout Positive Regulator LM1084 in TO220 package for delivering variable output voltage. Input - 18 VAC/DC. Output - variable output from 1.2 ~ 15 V @ 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. Zener trimmed band gap reference, current limiting and thermal shutdown (provided by IC feature). Power Battery Terminal (PBT) for easy input and output connection.
