Q: Can you produce LED driver; if we give you the parameters?
8 r! \9 {. i1 kWe 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
A: We need LED drivers; 55 – 60 W and 70 – 75 W; 300 mA; from 28 to 42 V,不太对吧,参数不对,搞错吧.
$ E3 }  I& r$ z3 e3 y+ d7 aQ:正常的参数是啥
A:正常参数太多了,1400mA,0.3*42最大也就是13W这样啊
, L5 k1 W- I+ N6 l, \; X- b# cQ:多谢,后来和客户确认了：
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 connect them in parallel with 4 X 300 mA and 5 X 300 mA.
9 y, V$ A3 _  cSo, we need CE LED drivers:
7 o. U5 N: o# {) Z; Q1. 55 – 60 W; 33 – 34 V output voltage in one LED module; 1200 mA
5 g! r  Y3 O2 s6 a2. 65 -70 W; 33 – 34 V output voltage in one LED module; 1500 mA
) _, Q5 k* \7 q就是这个，然后
We sale per year around 30000 pcs. luminescent and LED lightings. So, the quantity will be around 15000 – 25000 pcs. per year.
1 T9 O& H, k7 o5 J) CBut first we want to receive 5 pcs. 60 W + 5 pcs. 70 W samples. We will test them in laboratories. We have to be sure, that they cover the EC requirments.
After that we will order around 100 – 200 pcs. to make lightings, which to give to our distributors.
: K; K* m0 ^. DTake attention, that we export lightings for several countries in Europe.
Please, send me information how much will cost the  transport for 10 pcs. samples to us.
