What does 12VDC mean?
2020-02-10

12V power supply is one of the most common power supplies in use at present. In general, a 12VDC output is obtained from a 100VAC-277VAC input using a combination of transformers,12V power supplies can be of two types: 12V constant power supplies, and 12V unconstant power supplies. 12V constant power supplies come in three styles: Switching constant AC to DC, Linear constant AC to DC, and Switching constant DC to DC.

12Vdc led drivers is to maintain a Constant Voltage during working regardless of the current variations. A CV LED driver is suitable for Parallel circuit LED lighting because they have an in built resistor to control the current, therefore a CV driver would be required to convert the AC power to the required DC voltage.
