Product Details

5-16 VDC Linear DC Voltage Power Supply Kit

This power supply kit is an easy-to-assemble source of 5 to 16 VDC linear DC voltage as is required by small power amplifiers and other compact electronic components. Although basic in design, the circuit will satisfy most electronic kit users' needs, especially beginner projects.

Two DC output voltages are available: a fixed regulated 5V for TTL use, and one that is variable from 5V upwards—maximum output voltage itself depending on the input voltage. The regulator's maximum input DC voltage is 16V. The minimum input voltage must be at least 2V higher than the regulated output voltage. All components are through-hole and can be soldered easily to the printed circuit board. As a valuable additional application, this power supply also provides the means to save batteries when using Nintendo Game Boy or Walkman-type portable devices.

Rated 5 out of 5 by from Great regulator for test bench power supply.Very easy kit to solder and assemble. Just remember to couple it with a stepdown power transformer 24+24 volts dc. I use it to power small amplifiers and led lighting projects. Lot of fun and educational tool for teaching DC circuits to anyone willing to learn about electronics.

5-16 VDC Linear DC Voltage Power Supply Kit

Applying power.

Can this unit just be hardwired to a power cord and plugged into a socket? Or is the 120 v too high a load? Does one need a 16V wall wort to power this? Or does it take the place of the wall wort?
Asked by: rs11
The input for this power supply is 7-25 VAC or 7-30 VDC.

What is this? Does this come with a wall wart?

Does it convert AC 120v to DC? If I just wanted to create a control circuit with a SPST switch and an led indicator to signal 3 DPDT relays, do I need something like this? (PS the relays are used to switch A/B speakers) Would I want to use this if I anticipate trying to at some point add IR receiving capabilities instead of the switch? Thanks.
Asked by: Davidlc
No, a wall wart is the power supply. It contains the transformer, diodes filter caps,etc. This kit is more sophisticated and is variable. You assemble it and it plugs into an AC outlet with an electric cord.

I have a 18 volt ac transformer would this work good on this and give me enough amps to run a small amplifier

Asked by: Computer Builder
If you are using 2x 4 ohm speakers for 2x5W you'll need to push 2x5W = 10W = P = I^2 x R = I^2 x 4. So I = (10/4)^-2 = 1.58A. For 2x 8 ohm speakers for 2x5W you'll need to push I = (10/8)^-2 = 1.12A. The latter will probably be more do-able since the voltage regulators of this TO-220 type will be able to push about 1A.

where do i find instruction manual

This was supposed to be included with my order, but was not. I am a a beginner and don't know where to begin.
Asked by: Airplane
There isn't really an "instruction" manual available for this device, per se. One can think of it as a "paint-by-numbers" sort of thing. There is a list of parts, here: PCB is marked on the top side to indicate the location of each component. Using the parts list to identify the individual components, one would simply place the leads for each component through the holes in the corresponding location on the PCB, very carefully apply solder from beneath, clip off the excess leads, and voilĂ ! You can also refer to the pictures on the product page if you're unsure of a certain component, as to where it should be placed, or how it should be oriented.

Will this handle a 3 amp load?

I'm building a project that has a 12vdc motor that operates @ about 2.3 amps with a peak draw on startup of 3.0 amps. I will use the 5v output to power an LCD display/counter. Is this unit heavy enough to withstand these loads?
Asked by: seegarman
This power supply is basically a battery eliminator and as such it lacks the capacity to handle a motor load of 2.3 amps continuous. This power supply might be sufficient to power your LCD display, depending it's size. Smaller displays require fractional amp current but large color displays can require 1 - 2 amps and this would also be too large of a load for this power supply.PE does carry a power supply that is part # 120-532 (below) this supply would be sufficient to handle your motor and could be regulated by various methods if the 12 VDC output is too large for your motor.

is there a way to safely test if this is assembled properly?

I ordered and assembled one of these power supplies, and as soon as i plugged it into the wall there was a loud pop and one of the parts blew off. I will be ordering another one as i don't give up that easily, but if this trend continues I will have spent as much as a pre-built power supply!
Asked by: Swilk G
The first thing you should do is study and diagnose what went wrong with the power supply you just built. Some basic techniques are:-- Examine everything with a magnifying glass.-- Use an ohm-meter to detect shorts.-- make sure you were obeying the instructions properly with respect to input voltages. -- this is a regulator, not a full stand-alone supply. You need an off-line transformer in front of it with a maximum voltage of around 24vAC. (preferably no more than 16v). DC can also work in a pinch.A more useful part for U2 is the LM317.
