Q: Can you produce LED driver; if we give you the parameters?2 {3 Y# g% }+ J1 m
We 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# |" s G, }4 K" X6 S
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.

Q:多谢,后来和客户确认了：
& R' a8 g9 C# F: k* \5 U7 o2 g CWe 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.

So, we need CE LED drivers:

( `5 ? ?+ h$ o$ `- M8 rWe sale per year around 30000 pcs. luminescent and LED lightings. So, the quantity will be around 15000 – 25000 pcs. per year.# F) f& Z+ T% Y& L- A; g$ p+ i
But 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.$ f- j) U- X- e0 N& B# Q
After that we will order around 100 – 200 pcs. to make lightings, which to give to our distributors.( ]* F2 P: I7 `3 j/ W- s% |
Take attention, that we export lightings for several countries in Europe.
' N& h5 w5 ?; y% N% d, R2 cPlease, send me information how much will cost the transport for 10 pcs. samples to us. [# j) H& q4 O/ z9 R7 Y. H
