All drivers are either constant current (CC) or constant voltage (CV), or both. This is one of the first factors you need to consider in your decision making process. This decision will be determined by the LED or module you will be powering, the information for which can be found on the LED’s data sheet.
WHAT IS CONSTANT CURRENT?
Constant current (CC) LED drivers keep a constant electric current throughout an electronic circuit by having a variable voltage. CC drivers are often the most popular choice for LED applications. CC LED drivers can be used for individual bulbs or a chain of LEDs in series. A series means that the LEDs are all mounted together in line, for the current to flow through each one. The disadvantage is that, if the circuit is broken, none of your LEDs will work. However they generally offer better control and a more efficient system than constant voltage.
WHAT IS CONSTANT VOLTAGE?
Constant voltage (CV) LED drivers are power supplies. They have a set voltage that they supply to the electronic circuit. You would use CV LED drivers to run multiple LEDs in parallel, for example LED strips. CV power supplies can be used with LED strips that have a current limiting resistor, which most do. The voltage output must meet the voltage requirement of the entire LED string.
CV drivers can also be used for LED light engines which have a driver IC on board.
WHEN WOULD I USE CV OR CC?
Most of Tauras products are constant voltage power supply. It’s suitable to led strip lights, signs lighting, mirror lighting, Stage Lighting, architectural lighting, street lighting and so on.
