Power factor will be higher than 0.9 when output loading is 75% or higher.
CEN-75 series possess superior working efficiency that up to 91% can be reached in field applications.
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)].
