I was definitely at the right place at the right time to snag those emitters, but have only put one of them into service so far. I am familiar with the CLG and HLG series 0-10V/pot dimming functions these type of drivers accomodate and have also experimented with the associated 0-10V RF remote controllers in dimming other expensive luminaries. A 100K external pot can take the place in most instances, and Ive considered modding my “A” series Meanwell with such an external non-linear pot. But now that Ive been running mine at 100 watts, I find that I dont want to turn it down. lol
From Meanwell:
What is PFC?
Ans:
PFC stands for Power Factor Correction. The purpose of PFC is to improve the ratio of apparent power and real power. The power factor is only 0.4~0.6 in non-PFC models. In PFC models, the power factor can reach above 0.95. The calculation formulas are as below:
Apparent Power=Input Voltage x Input Current (VA)
Real Power= Input Voltage x Input Current x Power Factor (W)
From the environment friendly point, the electric power plant needs to generate a power which is higher than apparent power in order to steadily provide electricity to the market. The real usage of electricity should be defined by real power. Assuming the power factor is 0.5, the power plant needs to produce more than 2VA to satisfy 1W real power. On the contrary, if the power factor is 0.95, the power plant only needs to generate more than 1.06VA to provide 1W real power need. It will be more effective.
