Description
Our 3 Volt 1 amp power supply adapter can run 1 - 50 LEDs and is Guaranteed to correctly run all of our 3 Volt DC LEDs
- 1 Amp will run from 1 - 50 LEDs
- 2 Amp will run from 1 - 100 LEDs
These regulated power supplies will put out exactly 3 Volts of power if you hook one single LED to it, or hook the maximum number of LEDs to it. They are regulated and able to run delicate electronics like LEDs and circuits.
These UL listed Adapter / Transformers convert wall current to 3 Volt DC output, perfect for our 3 volt LEDs.
Input: AC 120-240V 60HZ 10W Output: Regulated 3V DC 1000mA Center positive
Dimensions:
- Plug Diameter 5.5mm
- Length 10mm
- 57 inches from the Adapter body to barrel plug
We also have a screw thread power jack that can be mounted on a panel or a flat exterior surface of your model.
Panel Mount Power Jack 
|
Standard Power Jack is Included Free
The power jack receiving end plugs into our power adapter. At the other end, we have added a short piece of red and black wire.
Here's how to use it:
- Mount this small power jack inside of your model.
- Connect the red power lead to all of the red leads on your LEDs, use shrink tube or electrical tape to protect the connection.
- Connect the black power lead to all of the black leads on your LEDs, again using tape or shrink tube.
- Make your connections on the inside of the model.
- When you are finished, plug in the adapter and enjoy your LEDs for years and years!
Adapter with On/Off Switch:
- The on/off switch can run 100 LEDs.
- The switch is mounted 6 inches from the barrel plug.
After plugging in the adapter, just press the switch once to turn on all lights, press again to turn off.

Wired Connector
Easily change from 3V wall adapter over to battery and back!
If you like to run your lights on wall power, and still want the flexibility to sometimes run on AA batteries whenever you are not near a wall outlet, we have a solution.
With the "battery option" solution, wire your lights to the "male plug". Now you can use the quick connector to easily switch from 3 volt wall adapter to AA battery pack and back!
Add the "battery pack" to your order on this page. You will get:
- Power Jack with a female connector added.
- AA holder/switch with a female connector added.
- 1 "male plug" to wire to all of your LEDs.
Easily and safely change back and forth at any time!
Regulated Power Adapters
No more bulky, heavy, heat generating, transformers! This new high speed digital switching circuitry shrinks both the size and weight of the transformer! It also greatly reduces heat "losses", and increases the available output power. The result is much higher efficiency as well as a much more tightly regulated output voltage.
By comparison, A non-regulated adapter can put out up to 5 volts of power, which is too much for 3 volt LEDs. We do NOT recommend connecting our 3 Volt LEDs to a non-regulated adapter as the potential output voltage would be too high. This Transformer is one of the newer "switching adapters" which regulate the output voltage without all of that heat the older adapters can produce.

I've been working with miniatures for years now, and I think lights really add magic to them. I have also worked as a lighting system designer on megamansions, and wanted something more robust than the often clunky solutions available from the average dollhouse shop. This led me to Evan Designs, and their robust offerings. From controls, to fiber optics, to specialty LED configurations, they have everything I could want to create, retrofit, control, and properly illuminate a miniature scene. Shipping is fast, communication is clear, and each listing provides detailed information on wiring, compatibility, etc. You really have become my go-to for all things lighting.

I love all the different items and options Evan Designs has to offer. I love that they are always coming up with new ideas and items that I can continue to use in the projects I am making.

All items that I ordered met or exceeded my expectations. Thanks.

Truthfully, I haven't had a chance to use my purchases, but the process was very easy; good website and easy checkout. What more could you ask?

Went looking for a power supply for my model railroad lights on the web and found Evan Designs. They had exactly what I needed and at a very reasonable price. Their site shared a video of how best to attach the fine gauge wire together that would eventually save me a lot of time and trouble. Highly recommend them for your project needs!!!

Evan Designs always takes great care of their customers. I have become “that customer” who always has a special request, and I am always treated with the utmost kindness and respect, even when my busy brain sends mistypes in emails, or I ask a seemingly obvious question. The people at Evan Designs are amazing! I will be a customer for as long as they are a business. Their products are superior in quality, function, and design. Highly recommend!

I'm fairly new to miniatures and I wanted to connect my dioramas to one power supply. Colin answered all my questions and suggested the best set up for my needs. My order came very quickly and is just what I wanted!
