Q: Can you produce LED driver; if we give you the parameters?
9 v4 N. ]) p. a/ y) r4 `2 [3 ZWe 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( M! a) p. u0 V& Y2 Z5 J' B
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.. J! T) ^/ m8 Z0 [$ ?( o
Q:正常的参数是啥
- F/ `( p5 b4 u4 JA:正常参数太多了,1400mA,0.3*42最大也就是13W这样啊* s, S' e: g! U. X+ u0 ~ B
Q:多谢,后来和客户确认了：
$ _- D0 `0 e* ] p) QWe 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.* C. q. c, H" O$ [# ^$ {5 V+ A
We connect them in parallel with 4 X 300 mA and 5 X 300 mA./ M, ]3 e; }! |1 p$ t
So, we need CE LED drivers:
& G. c2 _5 ?2 G6 o$ `) B- B1. 55 – 60 W; 33 – 34 V output voltage in one LED module; 1200 mA" a V6 k0 d' v) T. ~- W* l
2. 65 -70 W; 33 – 34 V output voltage in one LED module; 1500 mA. Z3 X7 t% e L- K- _5 \
就是这个，然后
2 r2 u2 ^/ W4 j* {6 iWe sale per year around 30000 pcs. luminescent and LED lightings. So, the quantity will be around 15000 – 25000 pcs. per year.
1 X8 ]( M l- }+ GBut 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. c6 z, l# T0 ^" x3 ]9 T
After that we will order around 100 – 200 pcs. to make lightings, which to give to our distributors.
9 t/ N' s: J0 E2 b# vTake attention, that we export lightings for several countries in Europe. 6 W, }# e" Q% f" t) m
Please, send me information how much will cost the transport for 10 pcs. samples to us.( g- J. y8 D7 Z5 L+ u, v; E' ]" R
