Sorry for the stupid questions - read the forum, I found some similar themes, but still do not understand how it considered options ... Background: There Feed SDM 3528 30LED (2,5W, 12V, 0.4A). It is necessary to connect it by an autonomous power supply (batteries?). How to calculate how much to batteries, which power, how long will shine tape (pieces are 10 to 50 cm - for each interest payment). the same question - whether it is possible to connect xenon svetla directly to the battery or need extra controllers? The result should diode strips with battery length of 10-50 cm, power supply xenon svetla must be the minimum size. If anyone has alternatives to the creation of such mechanisms (like when I saw the dog collars made of LED strips xenon svetla on but not quite figured out how to do it) I will be very grateful for a detailed description of the calculation (with formulas) so as not to torment xenon svetla more with silly questions. I myself unfortunately in Electrical generally do not rummage so please treat condescendingly Thanks in advance! Top Reply with quote Quote +
The larger the battery and shorter tape, the longer will burn. And naoborot.Vot vsё.Ot and batteries are not considered, very grateful rabota.Batareyki raznye.Krome experiment did not vyydet.Dazhe priblizitelno.I no controllers are not nado.8 pieces xenon svetla of batteries of 1.5 volt series.
Battery capacity delish on current consumption, will receive an approximate burn time. 50cm tape will eat 5 times more current than 10cm, to measure current, you can calculate and himself. Top Reply with quote Quote +

If I understand correctly that the total capacity of 600 * 4 = 2,4Ah that the consumption of the tape 0.4 is enough for 6 chaov. In view of the frequent on-off xenon svetla switch - 4 hours of continuous svecheniya.Sootvetstvenno 10 cm piece of tape - 40 hours and then descending ... Will for such batteries xenon svetla satndartny power supply 4hAA? Top Reply with quote Quote +
If I understand correctly that the total capacity of 600 * 4 = 2,4Ah Port daisy capacity will remain the same (600 mAh), and the voltage will be added. With parallel connection the voltage will remain the same, and the capacity will be added (600 mAh * 4 = 2.4 Ah). Top Reply with quote Quote +
Generally xenon svetla the author and buy a 12V 1.2A battery charger and lead to him, the price AKB ~ 300 p. ~ 300-500r charger. And the batteries here blasphemy, 8 pieces for 2-3 hours, and trash. http: //www.scanlight...id_product=1777 http://220va.ru/product/la12-900.html Do not think for advertising, xenon svetla but is now in the forum links hide somehow nepoluchaetsya.
On the battery capacity of the brand write? Not for kakih.Emkost-rasschёtnaya quantity. It depends on the discharge conditions, and can vary in one and the same element 2-3. Therefore, do not write.

Absolutely. For any normal battery charger is needed. In principle, such batteries still and the driver would not prevent deep discharge. But this fee compactness, inadezhnost and durability. Top Reply with quote Quote +
guys, hello! help me please. I want to stick a shelf LED strips, the length of the shelves of about 1 m., of 2 pieces. that for this I have to buy and how it all connected? Top Reply with quote Quote +
Two strips and power supply 12 volts. xenon svetla The current, which is designed to power supply must be chosen considering the current consumption of ribbons. widespread tape consume about 0.4 A per meter. Ie 2 meters xenon svetla you need to buy a PSU with a load current of at least 1 A. connect
