VDC is a three-letter abbreviation (an initialism) with multiple meanings, the most common is volts (V) of continous current (direct current (DC)), in contrast to VAC.

Care must be taken not to connect DC devices (such as DC electrical motors) to alternating current (AC) sources, as DC devices can be seriously damaged by doing so. The voltage itself is also important, as a device must never be connected to a power supply generating a higher voltage than the device is rated to handle.
