Q: Can you produce LED driver; if we give you the parameters?
' k! U4 I7 y$ ^) b( 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
! H; s2 Z6 U2 o! F! `# KA: 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.
Q:正常的参数是啥
! Q# p* P8 m) G* y4 m; oA:正常参数太多了,1400mA,0.3*42最大也就是13W这样啊
+ D) h/ i. {& F+ g$ ?Q: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.
1 `3 J4 I$ K3 G; C, b- ^- E# MWe connect them in parallel with 4 X 300 mA and 5 X 300 mA.
, A/ V; o9 D: E! z6 ?So, we need CE LED drivers:
1. 55 – 60 W; 33 – 34 V output voltage in one LED module; 1200 mA
4 i% j, f: w# ]  v9 R. d( x& G0 L/ R2. 65 -70 W; 33 – 34 V output voltage in one LED module; 1500 mA
( W6 z5 \1 h% O就是这个，然后
& V7 P$ M" {/ ]7 `3 E3 FWe sale per year around 30000 pcs. luminescent and LED lightings. So, the quantity will be around 15000 – 25000 pcs. per year.
' f# d. A: y- s5 a  wBut 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.
$ O; Y" g- V" x/ A) x& \Take 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.
