سؤال: Does this lamp need an additional heat dissipation or/and a cover?

السؤال بواسطة wgwgwg على 2018-10-04 06:27:22

ElmaEes The lamp can be mounted directly on the wall or ceiling. The reflector also serves as a heat conductor for cooling.

wgwgwg Olá, Este é o simples e também o caso com preços razoáveis. Basta procurar: Inversor variável do vfd da movimentação de freqüência 220v / 380v 1.5kw / 2.2kw Mas você tem que esperar que o 1,5 kW + x como fonte de alimentação deve estar em uma fase.

wgwgwg Question and answers use different names for the three functions. The correct answer is: M means momentary switch, T means toggle switch, open means switch A activates and switch B releases the relay .

سؤال: Where can I find the break resistor?

السؤال بواسطة Frank Gormanns على 2018-02-05 08:08:16

wgwgwg This VFD operates with the IGBT-Module called 7MBR10VKC-120-50. A brake-function is integrated in the chip. But it only brakes down with the power which is available to drive the motor. So if you have a high mechanical load on your drive and it has much energy stored in its rotating mass, may be the programmed breaking time will be to short. An error will be displayed. You can test how long it takes to bring it up to full rpm. About so long will be the shortest time to brake it down. An external resistor would produce a lot of heating and it is much business to install all correctly. I never needed it.

سؤال: Shell we connect to 3 phase AC, 5HP motor to control the speed?

السؤال بواسطة lakshman lucky على 2018-09-13 12:57:51

wgwgwg Never do it. 1.: 5 HP are eqivalent to 3,8 kw. That is another galaxy. 2.: This is a VFD for input and output 1 phase 220V. Not for 3 phases. Look for a more expensiv model and you will have success.

سؤال: What about the dimensions of 30 and 50 W lamp?

السؤال بواسطة wgwgwg على 2018-10-04 06:28:08

Periphery 30w is 170*110mm, 50w is 250*118mm.

wgwgwg Not in this shop. Look in aliexpress. And let the offer confirm by the seller. Normally VFDs tahe the original voltage and change frequenzy. Changing voltage to a higher level along with this output (Watt) is not so easy and will be more electronic and probably more expensiv.

سؤال: You mention that is a 380V input/380V output but the scheme shows a 220V input/380/output can you precise ?

السؤال بواسطة mica58anlu على 2018-03-03 04:31:36

wgwgwg No problem, the oictured schemes are multi valid. Only the declaration of the product in the offer is important.
