Q: Can you produce LED driver; if we give you the parameters?& ~# J: t1 r2 A( d1 J
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7 ]3 t/ X8 t q
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., ], [$ v4 J7 l9 I; a
Q:正常的参数是啥9 O- r5 M1 H8 O' }. {* _( f+ f) `7 V
A:正常参数太多了,1400mA,0.3*42最大也就是13W这样啊

+ D7 N6 `5 U6 S7 BWe 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.& h) A0 ?, P( S; l% }' A8 O p& N
We connect them in parallel with 4 X 300 mA and 5 X 300 mA.0 T. r1 C/ f4 ^- c8 {* `3 y
So, we need CE LED drivers:

就是这个，然后0 d0 r4 ?. @' F" u$ Z: o" Z9 ~7 X
We sale per year around 30000 pcs. luminescent and LED lightings. So, the quantity will be around 15000 – 25000 pcs. per year.
7 q" I; z+ f$ I! dBut 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.

Take attention, that we export lightings for several countries in Europe. 1 V2 M% p: o Q9 E! t$ \9 H
Please, send me information how much will cost the transport for 10 pcs. samples to us.
