Q: Can you produce LED driver; if we give you the parameters?
& t2 q% K3 {$ Q' Y, h3 t$ d2 r' u" VWe need LED drivers; 55 – 60 W and 70 – 75 W; 300 mA; from 28 to 42 V.这个驱动谁可以做' \) ?+ G: ^; `* b% V

We use LED modules Samsung; 48 W (4 X 12 W) and 60 W (5 X 12 W); 230 V input voltage; 33 – 34 V Output voltage in one LED module 12 W.

We sale per year around 30000 pcs. luminescent and LED lightings. So, the quantity will be around 15000 – 25000 pcs. per year.
