1.2V_to_37V_PSU_pic

This project provides a variable output power supply ranging from 1.2 to 37 V @ 1.5 A.  Uses industry popular LM317 in TO3 package for delivering variable output voltage.

Specifications

  •  Input 40 VDC or 28V AC 2Amps
  •  Output : 1.2 to 37 V @ 1.5 A regulated low ripple DC voltage
  •  Heatsink for regulator IC
  •  Onboard bridge rectifier to convert AC to DC
  •  LED indication at input of IC
  •  Thermal overload/short circuit protection (provided by IC feature)
  •  Screw terminal connector for easy input and output connection
  •  Relimate connector for connecting potentiometer (POT) to the PCB
  •  Filter capacitors for low ripple DC output
  •  Four mounting holes of 3.2 mm each
  •  PCB dimensions 91 mm x 66 mm

What are the diffrence between LM317K , LM317T etc..
Thankyou…….

Charles

is the potentiomiter 5 volt logic? Could this be removed and have the voltage controlled by Arduino PWM?

Castro

we cant change the Voltage or not like 28-0-28 i change to 25-0-25 he accept that voltage

Castro

How about changing the voltage in 25-0-25?
