I have a fiber optic Santa, 4' high, and I no longer have the adapter that goes to it. On the bottom it says "use only a 12v/25mv adapter" it also says no more than 20 watts. Can you help me determine which adapter I need? thanks. I'd love to get it "yesterday". thank you.
Hi.. In order to find out the size of power supply you need, you will use a very simple calculation. You already know that the voltage is 12V. You also know the wattage as 20 Watts... To find the Amp size of the unit, you will just divide the wattage by the amperage. so 20W / 12V equals 1.66 Amps... Amperage represents the maximum power usage your device needs so you need a power supply that can provide the same or greater amount of power. In this case, you would round 1.66A up to the nearest whole number, which is 2A... You can also use a bigger one if you wish, as the power supply will only give whatever amp load the device you are running needs.. Here is a link to the power supply you need. It is a 12 Volt 2 Amp Power supply: http://12vadapters.com/adapter/power-supply/12v/2-amp-ul-listed-12-volt-2a.html
Hi.. I hope you can answer my question. I have a small hand router I use for carving in wood. It says it needs a DC power supply, and it is 60 Watts... I bought a 5A power supply, but it seems like it only works for a second, then the motor stops... What is wrong?? I tested the Power SUpply with something else, and it works..
Hi Jen, Thanks got your question. I know the problem. A DC motor has some special considerations when selecting a power supply. Your motor probably has a continuous use of 5A of 60 Watts, but that is only part of the picture. There is something else called peak power, which is the startup power necessary to get the motor running. The peak power is a lot more than the continuous use. When you press the button, for the motor to overcome resistance, and start turning, it usually pulls about 50% more power.. so for a 5A motor, up to 8A.. This happens for a second, then once it is spinning, it drops to continuous use power level. What is happening in your case is that the power supply has a shut-off circuit that protects the power supply... Once your load passes 5A, the power supply just shuts off... In order to fix this issue, you need a power supply that is larger than the peak power of your motor.. So if you are using a 60W motor at 12 Volts, you should order the 12V 8A, or even 10A power supply... Good Luck!
I am looking for AC adapter SA-48C for my Phantom chess player. Thank for your attention. Pedro
Hi Pedro... I can't answer based on a specific brand.. I need to know the Voltage and the Amperage of the device you want to power. Also, it would be good to see if it has a standard connector, or a non standard connector. Most 12V devices use a power supply with a 5.5mm x 2.5mm barrel connector..
This article tries to explain the function of an AC/DC power supply by showing the difference between AC and DC current, the two major forms of electrical power that exist today.
