User Marsha Carlson Asked:

AC Adapter input 100-240v, output 12V- 3amp needs replacement for our Lorex monitoring system Problem we are having is that in the possible replacements found, the circular plug although it seems to be same size outside diameter, is actually 1/8 smaller on the inside diameter and will not fit. How can we find apaptor with plug that fits. Any help appreciated

Our Technician Answers:

Hi M**** The majority of 12V 3A power supplies use a 5.5mm x 2.5mm connector. I would recommend trying that one because it is the standard. A small percentage of 12V Power Supplies use a 2.1mm interior barrel instead of 5.5mm. If the barrel is a little smaller, the 2.1mm should work.. Also, in most cases, a 2.5mm barrel will work with the 2.1mm plug anyways.. It will just be a little loose... The only other possibility will be to buy and a use a measurement gauge.. it is something that looks like a ruler, and has 2 points that slide apart and together to give an accurate measure of the power supply connector.

User Michael Asked:

I'm trying to power a belkin tunecast 2 fm transmtter. The input hole is very small which adapter do i need? Thanks in advance for your help.

Our Technician Answers:

Most power supplies that are 12V come in one of two types of connectors. The vast majority of 12V power supplies between 1A and 5A (Amps) use the standard 5.5mm x 2.5mm connector. This covers over 95% of all power supplies... There is a small minority that use a 5.5m x 2.1mm tip.. These are usually in the 1A to 2A range... Please note that in many of the 2.1mm connector units, the 2.5 mm connector will still work as they are so close in size.

I have a Christmas snowman (about 4 feet high) with a power adapator that fell and cracked and I need to replace. It's an AC Adaptor Plug in Class 2 Transformer Model AD-1202000AU Input: 120VAC 60 Hz 200mA Output 12 VAC 2000mA P/N GJE-AC57-124 It also notes Listed 8G10 (could be a 9G10) E200322 The plug in is two little plugs...one fllatish and one roundish. (?) It's definitely not a barrel plug in. It runs the power for a light for fiber optics in this decoration. Do you have anything like this? I've looked all over. Thanks.

Our Technician Answers:

High K*** All te power supplies we carry have either a standard 5.5mm x 2.5mm DC connector, or a 5.5mm x 2.1mm Dc connector. For any non standard, you would need to cut off the tip that comes with it, and splice on a different one using electrical tape.. it is quick and easy...

Choosing a Power Supply for A DC Motor

This article deals with the special considerations you must make when you are choosing a power supply for a a DC motor. These special considerations require an understading of continous vs peak draw, and how they effect any specific 12V Power Supply.

Power Supply News


When choosing a power supply for a DC motor, you must know two things about a motor. These are the continous draw of the motor, measured in AMPS, or Watts, and the Peak Draw. The continous draw is the amount of power, or load, that the DC motor pulls from the power supply when it is already running. This is usually a smaller number than the peak draw. It is often measured in Watts, which is equal to the Amperage of the motor, multiplied by the voltage. So a 5 Amp DC motor running at 12V will consume 60 Watts of power. This is called the continuos draw, and must be less than the contimous load rating of the power supply. THe other major factor to consider when selecting a power supply for a DC motor is the peak draw. This is the amount of draw when the motor is just starting up, going from a stopped to running state. This peak power limit is usually significantly higher that the continous draw... So if a motor draws 3A on continous running, it might draw up to 5 Amps or more for a few moments as it starts running. Most switching power supplies have a protection circuit, which will turn them off if load peaks beyond it's safe capabilities. You must ensure that the peak rating of the motor does not surpass the peak shutoff protection of the powr supply. An example is, that if you want to power a DC motor with a 3A continous draw, you must assume the peak draw as about 50% more, so you should select a 5A power supply. This will be enough to get through the peak power usage, and will of course have no trouble running the continous load of 3A. Hope that makes it clear.....
