HLG-185H series possess superior working efficiency that up to 94% can be reached in field applications.
HLG-185H series possess superior working efficiency that up to 94% 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).
