Coops You must order TWICE. Place one order for one pcs 1000-4000 Then go back to product page and buy again but choose 3000-8000 model. Then select shopping cart and select both items, go to next page and check shipping cost (it should be very similar for 1 or 2 pcs from same warehouse location).

Coops It is your choice what country you use this in. The size of speakers is totally irrelevant, you can use any size.

Q: Is this item 240 volt suitable for Australian power sources

zapytał tuffy na 2018-06-23 01:56:38

Coops YES it is suitable for Australia, which is NOT 240V since 1980 (60 years ago). The voltage there is 230V +10% -6% so that means between 216V and 253V. Obviously a 220V product is within same voltage range, and will work fine

Coops YES OF COURSE you can connect it to a car battery. That is exactly the reason that it has 12-15V input connections on the rear panel. The size of speaker is not relevant or important.

Q: What is the function for 12V 10-15A input?

zapytał cicibacsi na 2020-02-04 04:27:47

Coops This 12V input is so you can power the amplifier with 12V car or boat battery, instead of 220V mains power.

Coops The DC input is for 12V car battery, etc. It is pointless to connect it to a 12V mains adaptor, since this amp has 220V mains transformer inside.

Coops The size of speakers is TOTALLY irrelevant. What matters is power handling capacity and efficiency of speakers. If you use high powered but inefficient speakers, it will not be loud and you risk damaging the speakers from amplifier clipping. If you use highly efficient speakers, you will not need to turn the volume of amplifier very high to get a loud sound. So you don't need power speakers if they are efficient ones. Once again, the size of speakers is not important in any way !

Coops I found same problem with FNB28. This is how I solved it.... 1. Don't plug FNB28 into USB port. 2. Open "DFU Tool" Windows software. 3. Hold K1 key (closest to USB Plug), then plug into computer. 4. FNB28 screen will be black

Coops It doesn't need to meetbelectrical codes, and of course it is not "safe" as supplied. This component is designed to be installed INSIDE another device or an enclosure. It is NOT a stand alone device nor to be used without proper installation by competent person.

Coops The item description clearly states that batteries are not included. The item description also clearly states what type of batteries are required (2 x CR2032 button cells)

Coops Use a computer and "select" the desired page sections by holding mouse button an dragging to select. Then COPY that to clipboard. Next, open word processor like MS Word and PASTE the information. Do formatting and editing as required, the SAVE.

Coops 2200W angle grinder maybe has starting current much higher than 4000W, however if it really is 2200W then that is a HUGE dangle grinder and it might have so-called "soft start" circuit so that it does not jump out of you hands when you switch it on. The only way to be sure is to use special power meter to test the grinder, or just buy this and test it.

Q: Does it output DC or AC voltage?

zapytał Gustaf na 2020-04-13 07:18:35

Coops WRONG ANSWER. This has input 220V AC and output is chopped waveform AC. It definitely does not output DC, and there is no reason to ask this question.

Q: Possible to ouput 220V if the input is 30V/5A?

zapytał BG155514143 na 2020-10-28 03:09:40

Coops No, of course not. This is a speed controller, not a boost circuit with inverter.

Coops This will only reduce power, not increase it... so will not help with your low voltage mains. The pump will not work anyway, as it is probably uses an Induction Motor and these speed controllers are only suitable for "Universal Motor" that use brushes inside.

Coops Instructions and PCB clearly show 2 or 3 turns for Primary winding. You have used 5 or 6 turns... that is why your sparks are not impressive.
