load efficiency (%) npf-40 series possess superior working efficiency that up to 90% can be reached in field applications. efficiency vs load (48v model) 40w single output switching power supply npf-40 series file name:npf-40-spec 2015-05-28 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 vo(%) 100 60 50 100 (min.) io (%) constant current area hiccup protection constant voltage area (a) (b) (c) 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. 75% 77% 79% 81% 83% 85% 87% 89% 91% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% 277v 230v 115v
