What does 12VDC mean?

What does 12VDC mean? it is related to LED Driver and Safety.

Any current whose direction of current does not change with time is called DC voltage. The current value can be all positive or all negative. There are two types of direct current: steady direct current and pulsating direct current.

The voltage whose magnitude and direction do not change with time is called DC voltage. In a DC circuit, the voltage applied at both ends of the power supply, a certain circuit, and both ends of the component is the DC voltage. For example, the voltage at both ends of the flashlight battery and both ends of the light bulb are DC voltages. Due to the existence of the series-parallel relationship, the parallel phenomenon of electrical equipment has increased (resistors in parallel have a shunting effect).

There is a shunt current in the parallel branch, and a "shunt voltage" is generated when the shunt current passes through the electrical load (the shunt voltage is equal to the product of the branch current and the branch resistance in value). For example, the test voltage and current in a multimeter can change the range by using the partial voltage of resistors in series and the shunt of resistors in parallel.

The choice of voltage level is an extremely complicated matter. In fact, choosing a higher voltage can indeed save a lot of wires and energy, but it will increase the cost of switches or electronic components, and it will not save much money.

If we choose 100-120VAC when we start to develop electricity, it will reduce a lot of funds in the direct use of rectifier circuits, and it will be safer, and even power line interference sources will be reduced a lot.

Every LED Driver is rated in accordance with it’s capacity to handle power.

Power= Voltage X Current

So,Output: 12Vdc 1A means this led power supply can handle ( consume or generate) 12Watts of power
The same,Output: 12Vdc 2A means this smarts led driver can handle ( consume or generate) 24Watts of power

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.


Low-voltage 12v lamps can be installed flush on the ground, hidden in the landscape, installed on/around a fire pit, placed in the water and many other locations. The variety provided by low-voltage lamps has unlimited design capabilities


The low-voltage lighting is powered by the home operation, and the home operation returns to a single transformer located on the property, which reduces the home’s 120V voltage to 12V. The entire system does not require other power sources, only one socket is required.


Today the cost of driver led 12 volt have reduced in operating costs and installation costs. Beautiful power supplies are now available. 12V LEDs now provide higher output than before, and Smarts has more options to use. led power supply voltage 12v looks attractive, and they tend to have a more beautiful appearance.



12Vdc led drivers

so, what is a 12v DC power supply?


12Volt power supply (or 12VDC power supply) are one of the most common power supplies in use today. Linear regulated 12Volt power supply regulate the output using a dissipative regulating circuit. its extremely stable,have very low ripple&have not switching frequencies to produce EMI.
