Power Supply Kits For Groups #3 - 10 Sets (#4442)
This Adjustable +Voltage Power Supply Project Kit is designed around the LM317T 3-Terminal Adjustable Voltage Regulator in the TO-220 package. It is capable of supplying in excess of 1.0 Amps over a range of 1.5volts to 20volts output.
This kit consists of the PCB, Schematics, and parts required to build a 1-amp (or more), highly regulated Adjustable DC Power Supply. It requires an input AC or DC voltage source (3 V to 18V) from a transformer, such as a wall-mount type. A heat sink (not supplied) may be needed for the LM317T, depending on your application.
The output voltage is varied with a potentiometer and is very steady and accurate even while the input voltage varies. The output can be varied from around 1.5VDC up to 20 VDC depending on the input voltage and the choice of resistors. This circuit is perfect for those that want their own small but powerful power supply. It can be used on the bench or as part of your project. It is small enough to fit in robotic vehicles and such.
The maximum input voltage is 18VAC or 25VDC. Do not connect this directly to the 120VAC line.
This kit does not include the tools you will need to assemble the circuit. You will need tools such as a soldering iron, solder, wire cutters, etc. To assemble the kit, open and print the Schematics and the Parts List below. The General Instructions are helpful notes.
