One of the most commonly found power source for many of our consumer electronics is the 12V power supply. In most cases, these power supplies will plug into a standard 120V electrical outlet. Although this is the most common method to power this type of power supply, you may find yourself in a situation where you only have access to Hamerville Media Group Email a 240V outlet. In this case, you will need to utilize a 240V 12V transformer. This type of transformer is something that is normally used by electrical hobbyists, or some lighting applications. Whether you are looking for a standard 12V power supply, or a less common 240V 12V transformer, it is important to understand a few things.
One of the most important factors when choosing a power supply is the power requirements of the device that you need to power. You should know the devices’ overall voltage requirements, the amount of current it draws and what Electronic Equipment List restrictions exist regarding polarity. This is especially true if your device requires DC voltage. DC devices are much more sensitive to electrical polarity than AC plugs, which can be inserted in either orientation.
In a nutshell, a 240V 12V transformer takes the high-voltage of a 240V outlet and converts it into a usable 12V current for your electrical device or lighting system. One of the places that you will find such systems is for landscape lighting or other outdoor electrical situations. Because of the amount of power that these transformers handle every day, they are often equipped with a system of fuses. These fuses help to protect the transformer and your electrical equipment from any overloading. Whenever an excessive amount of electricity flows through the transformer, its fuses will “fail”, effectively stopping the flow of electricity from reaching your delicate electronics. This safety mechanism can be very instrumental in saving both your electronics and your life. In most cases, you can then replace the fuse to restore operation.
Regardless of the type of power supply that you are using to power the devices and systems around your home, it is paramount that they be used safely and properly. Before plugging a device into any power supply that did not come pre-packaged, always match up the output of the supply with the information that is listed on the device itself. This is especially true with adjustable, “universal” power adapters. While these adapters can be very handy in many situations, they can also lead to the early death of your electronics if you have them set on a power setting that is too high.
To avoid doing this, simply look at the voltage rating that is typically located next to the power inlet on your device. This will tell you exactly how many volts the device requires from its power supply, making your job of choosing a power supply easy. Whether this is a simple 120V adapter, or a more advanced transformer that connects to your 240V system, taking this step will ensure that both your device and your safety are maintained.
