What does 30VDC mean?

30VDC stands for 30 volts of direct current. It indicates a constant electrical voltage level of 30 volts that flows in one direction, as opposed to alternating current (AC), which periodically reverses direction. This term is commonly used in electrical engineering, electronics, and power supply specifications. In practical applications, 30VDC can be found in various devices, such as battery systems and certain types of power supplies.
