What does 12vdc at 750mA mean?

12VDC at 750mA indicates a direct current (DC) electrical supply with a voltage of 12 volts and a current of 750 milliamperes (mA). This means the device or circuit requires 12 volts to operate and will draw a maximum of 750 mA of current. In practical terms, it specifies the power requirements for devices that run on 12V DC, such as certain electronics or LED lighting.
