Q: Can you produce LED driver; if we give you the parameters?
$ v' o7 G* ]# Y4 h; y# {( w5 r0 p# VWe 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0 ~. y9 X5 ?+ U N
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.
: j3 y( ~! B$ IQ:正常的参数是啥3 P. I2 M0 x5 t! O1 ?' \, ?- G' q
A:正常参数太多了,1400mA,0.3*42最大也就是13W这样啊3 g# O! u. K( X1 e L5 k9 w
Q:多谢,后来和客户确认了：
: Q6 J3 B1 r2 ~. ^( d) A) ?7 k4 \# \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.
4 ?) I( x. z) j0 e' V WWe connect them in parallel with 4 X 300 mA and 5 X 300 mA.
4 P3 ]- a8 t& u9 D% m# ySo, we need CE LED drivers:
~/ V8 ^+ [ ^9 l1 p* y: g1. 55 – 60 W; 33 – 34 V output voltage in one LED module; 1200 mA
1 [. V/ t$ n" ?6 d+ S# F( `2. 65 -70 W; 33 – 34 V output voltage in one LED module; 1500 mA
8 b, J9 T4 {+ y u% c就是这个，然后 |& Y7 M+ w- G+ [1 t1 P7 v
We sale per year around 30000 pcs. luminescent and LED lightings. So, the quantity will be around 15000 – 25000 pcs. per year.
2 D2 `' O( W$ e& uBut 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.1 I! D# u$ U6 x# f
After that we will order around 100 – 200 pcs. to make lightings, which to give to our distributors.
3 h, b! S. E0 D yTake attention, that we export lightings for several countries in Europe. & V5 W: O$ B6 H; U4 i4 ?9 X' i! d
Please, send me information how much will cost the transport for 10 pcs. samples to us.
