LED Strip – 24 Volt DC or 12 Volt DC?

Why is 24 volt DC better than 12 volt DC?

24 volt DC (direct current) systems are becoming increasingly popular compared to 12 volt DC systems, especially in industrial and commercial applications. There are several reasons why 24 volt DC is better than 12 volt DC.

First, 24 volt DC systems provide more power compared to 12 volt DC systems. This means that more devices and equipment can be run on a 24 volt DC system without overloading the system. This is particularly useful in industrial and commercial settings where multiple devices and equipment need to be powered simultaneously.

Second, 24 volt DC systems are safer compared to 12 volt DC systems. The higher voltage reduces the risk of electrical shock, making the system safer for users and equipment. Additionally, 24 volt DC systems have lower current levels, which also reduces the risk of electrical fires.

Third, 24 volt DC systems are more reliable compared to 12 volt DC systems. The higher voltage reduces the risk of voltage drop, which can cause equipment to malfunction. The lower current levels also reduce the risk of equipment damage due to electrical surges.

Finally, 24 volt DC systems are more efficient compared to 12 volt DC systems. The higher voltage allows for more efficient power transmission, reducing energy losses and increasing system efficiency. This makes 24 volt DC systems a more cost-effective option in the long run.

In conclusion, 24 volt DC systems are better than 12 volt DC systems due to their increased power, safety, reliability, and efficiency. These advantages make 24 volt DC systems a popular choice in industrial and commercial applications.

Why does 24 volt DC use less current than 12 volt DC?

24 volt DC systems use less current than 12 volt DC systems because the voltage is higher. The amount of current (measured in Amperes) that flows into an electrical circuit, is directly proportional to the voltage and inversely proportional to the resistance of the circuit.

So, when the voltage is doubled (from 12 volts to 24 volts), the current required to deliver the same amount of power will be halved. In other words, for a given power output, the current required is inversely proportional to the voltage.

For example, if you need to deliver 100 watts of power to a load, with a 12 volt system, you will need to supply a current of 100/12 = 8.33 Amperes. However, with a 24 volt system, the current required would be 100/24 = 4.17 Amperes. So, you can see that 24 volt DC systems use less current compared to 12 volt DC systems.

Lower current levels have several benefits. For example, lower current levels reduce the risk of electrical fires, increase the efficiency of power transmission, and reduce the size and cost of the wiring required for the system. These benefits make 24 volt DC systems a more cost-effective and safer option in many applications.

Is there a greater risk of electric shock from a 24 Volt DC system?

Yes, there is a risk of electric shock from a 24 Volt DC system, although it is generally considered to be lower compared to a 12 Volt DC system.

Have you ever shorted a spanner or metal object across your battery, where it marks or welds even the hardest of metals? Now you would think 24 volt DC would do more damage, but due to the lower current levels, it won’t be anywhere near as bad.

What is an electric shock? An electric shock occurs when electrical current passes through the body, causing injury or even death. The severity of the shock depends on several factors, including the voltage of the system, the current level, and the duration of the shock.

24 Volt DC systems are considered to be safer than 12 Volt DC systems, because the higher voltage reduces the risk of electrical shock. The higher voltage reduces the current level required to deliver the same amount of power, which in turn reduces the risk of electrical shock.

In conclusion, while 24 Volt DC systems are generally considered to be safer compared to 12 Volt DC systems, it’s important to remember that even low voltage systems like 24 Volt DC can be dangerous if proper safety precautions are not taken. It’s important to follow electrical safety guidelines and use properly rated equipment when working with any electrical system, including 24 Volt DC systems.
