Solderless Breadboard Adjustable Power Supply Kit (#2071)

Price: $8.99

This is the Solderless Breadboard Adjustable Power Supply Kit. It is a variable Power Supply designed for fitting on Solderless Breadboards. It uses the LM317T Adjustable Voltage Regulator. It includes a 1amp Bridge Rectifier with 1 large Aluminum Electrolytic Capacitor for initial filtering. There is also a .1uF cap for some noise filtering and a 1K bleeder resistor at the input. The output has a small filter cap and a Red LED with a 1K Ohm current limiting Resistor. The output range is from around 3.0v to 25vdc.

It was designed by us to neatly fit on the common Solderless Breadboards which is a very handy thing to do. It will convert an AC input into a DC output. It will also convert a large DC input into a smaller DC output. This is an extremely versatile PCB.

The maximum input voltage is 18VAC or 35VDC. Do not connect this directly to the 120VAC line. This Power Supply will accept AC or DC inputs. The input voltage must be 2.5v higher than the desired output voltage.

A heat-sink may be required to keep the Voltage Regulator cool, it is NOT supplied with this kit.The PCB is double-sided, plated thru-hole, made of .062" FR-4 epoxy glass. It has green Solder Mask (LPI) on both sides with white Silk Screen on the Top side and it comes with 4 mounting holes. The Voltage Regulator is located near one edge so that it may be heat-sinked if needed.

This kit is offered as a "Built & Tested" option for those that do not want to build the kit themselves.

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.
