Constant Current Mode

There are two major kinds of LED drive method "direct drive" and "with LED driver".

A typical LED power supply may either work in "constant voltage mode (CV) or constant current mode (CC)" to drive the LEDs.

Mean Well's LED power supply with CV+ CC characteristic can be operated at both CV mode [with LED driver, at area (A)] and CC mode [direct drive, at area (B)].

DRIVING METHODS OF LED MODULE

Typical LED power supply I-V curve

In the constant current region, the highest voltage at the output of the driver

depends on the configuration of the end systems.

Should there be any compatibility issues, please contact MEAN WELL.
