Q: Can you produce LED driver; if we give you the parameters?) v, [6 ?4 A- V. F3 F
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+ }3 t; l/ M) M9 ^* M
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.# B4 X& U$ t6 I! R [( R0 k
Q:正常的参数是啥
' e6 m- v6 G5 B! oA:正常参数太多了,1400mA,0.3*42最大也就是13W这样啊" K; q" c' r+ ]) j0 @# ?% M3 o8 D* D5 Q
Q:多谢,后来和客户确认了：
" ]+ d/ Z9 h0 t+ t g' N" n2 g8 LWe 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.# ] o; @# x: i0 V& [/ a$ y- C
We connect them in parallel with 4 X 300 mA and 5 X 300 mA./ f# k# z) e/ o P- S* I$ P, p$ r
So, we need CE LED drivers:8 G3 ]; p" N0 K8 A r2 e$ ?' p) g8 o

就是这个，然后
$ }/ b9 B3 R6 OWe sale per year around 30000 pcs. luminescent and LED lightings. So, the quantity will be around 15000 – 25000 pcs. per year.
2 U3 c' ~6 B2 bBut 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.% O( P, {1 V; t# O8 Y
After that we will order around 100 – 200 pcs. to make lightings, which to give to our distributors.% f2 o! D% a$ ~. P: r8 X1 m
Take attention, that we export lightings for several countries in Europe.
) S, K6 u: r; `# W# H+ n7 OPlease, send me information how much will cost the transport for 10 pcs. samples to us.
