HLG-40H series possess superior workin g eff iciency that up to 89.5% can be reached in field applicat ions.
EFFICIENCY vs LOAD (48V Model)
There are two major kinds of LED drive meth od "direct drive" and "with LED driver".
Typical LED power supply I-V curve
A typical LED power supply may e ither work in "const ant v oltage mode (CV) or consta nt current mode ( CC)" t o drive t he LEDs.
Mean Well's LED power supply wi th CV+ CC characteristic can be operated at both CV mode (with LED driv er, at area (A) and CC mode (direct drive, at area (B).
