What is VDC power?

VDC is an abbreviation for “Volt DC”. DC stands for “direct current”, which means that the voltage is constant (in contrast to alternating current, alternating current, in which the voltage oscillates constantly between positive and negative polarity).

What is VDC power?

So “VDC power” means nothing in itself, but “12 VDC power” means power that is supplied with 12 volts DC. (According to some style guides, it is more correct to write “V DC” instead of “VDC”, but “VDC” is common in industry.) If you want to talk about DC but don’t want to supply voltage, just say “DC”. And a note about the term “DC”: don’t think too much about what the words actually mean. DC really isn’t “more direct” than AC, and both terms usually refer to voltage, not current. But we stay with them.

VDC (Volts Direct Current) is the voltage of a direct current (DC) circuit. Direct current is a type of electric current that only flows in one direction. Unlike alternating current (AC), which changes direction periodically, direct current flows in a constant direction.

VDC stands for “volts direct current”

VDC stands for “volts direct current,” which refers to the electrical potential difference or voltage of a direct current (DC) power source. In contrast to alternating current (AC), which periodically changes direction, direct current flows continuously in a single direction. VDC power is commonly used in various applications, including electronics, automotive systems, telecommunications, and renewable energy systems.

The voltage level of VDC power can vary depending on the specific application. Common examples include 5V, 12V, and 24V DC power sources. These voltage levels are frequently used to power electronic devices such as computers, smartphones, routers, and LED lights. Additionally, VDC power is utilized in automotive systems to power various components like car batteries, headlights, and audio systems.

VDC power is often supplied by batteries, power supplies, or renewable energy sources such as solar panels or wind turbines. The consistent and unidirectional flow of current in VDC power makes it suitable for powering devices that require stable and constant power delivery.
