User M L Asked:

Hi, I am looking for a standard 12 volt/2 Amp cable with a barrel that Calle Baughurstis 5.5mm on the outside, and 2.5mm on the inside - center pin positive.

Our Technician Answers:

Hi ML. All the power supplies on this site come with the standard 5.5mm x 2.5mm barrel. They all center positive. So any of the 12 volt power supplies will match the connector that you need.

hi my electrician is wiring my solar lights so they ll last longer i need anything esp if its a plug thats 1.2volts and 600 milli amps and then i have to waterproof it any ideas of what i could use thanks

Our Technician Answers:

Hi Karynn.. For any outdoor application, you should use one of the waterproof water supplies. These can be installed outside... in the rain, (but not for submerged use). They come in 12 Volt 2.5 Amp Size and 12V Volt 5 Amp Size. For all load from 1A to 2.5A (12W-30W) use the 12V 2.5A, for all loads from 2.5A to 5A, use the 5A unit.. Simple as that.

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.....
