Q: Can you produce LED driver; if we give you the parameters?
1 F6 b& Y& v. }$ o$ c' ^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
. j: e# }/ w1 J: M2 S# L/ t* t8 _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.$ K. N v* f6 i6 V- ~/ `0 @
Q:正常的参数是啥! |# N) v3 W; u% t' d6 Q {' c' A
A:正常参数太多了,1400mA,0.3*42最大也就是13W这样啊
" M$ @1 X5 R% ]5 m$ j W9 l6 TQ:多谢,后来和客户确认了：
4 ]7 u0 u- u* U( pWe 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.
( S9 d7 S' B' h$ L! UWe connect them in parallel with 4 X 300 mA and 5 X 300 mA.. K- l- M& [# A' f) F+ \
So, we need CE LED drivers:
9 W. Z0 N" F p) k) B Q1. 55 – 60 W; 33 – 34 V output voltage in one LED module; 1200 mA
6 {' |3 P7 d6 _0 J8 `* g' U" _2 e2. 65 -70 W; 33 – 34 V output voltage in one LED module; 1500 mA- y- H6 g2 T V( y0 E1 K
就是这个，然后
5 m9 R- i: }! Y- GWe sale per year around 30000 pcs. luminescent and LED lightings. So, the quantity will be around 15000 – 25000 pcs. per year., r0 {( J3 u# m# j
But 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.5 P; f0 V% Q, ^/ ~
After that we will order around 100 – 200 pcs. to make lightings, which to give to our distributors.
( M0 y7 F% A( U) |* c! @1 n& T: v% J& YTake attention, that we export lightings for several countries in Europe.
1 `( ]5 U+ O/ _# J+ F8 iPlease, send me information how much will cost the transport for 10 pcs. samples to us.
