Q: Can you produce LED driver; if we give you the parameters?7 j& C4 ^5 _) D* v" ?0 v6 H* @
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
5 a! u, e9 A0 i, B( nA: 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) B" U6 s' }5 v% UA:正常参数太多了,1400mA,0.3*42最大也就是13W这样啊* M1 G M, ^& ^( _; I
Q:多谢,后来和客户确认了：0 j8 [4 e+ t3 L( f A
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.

So, we need CE LED drivers:

2. 65 -70 W; 33 – 34 V output voltage in one LED module; 1500 mA. q7 t1 A) e* [# }/ s, v: U: Q) P
就是这个，然后, |& d& }% }/ h
We sale per year around 30000 pcs. luminescent and LED lightings. So, the quantity will be around 15000 – 25000 pcs. per year.
; g) h) T0 r4 V, F# S2 z* FBut 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.) P- ^% y, ?0 J( X0 b; x8 T
After that we will order around 100 – 200 pcs. to make lightings, which to give to our distributors. T. V( v2 v0 K# z2 l: `
Take attention, that we export lightings for several countries in Europe. 6 A8 s0 j5 w1 @: _5 _$ b! u: u% J' z
Please, send me information how much will cost the transport for 10 pcs. samples to us.
