The panel, which is declared as 50W, does not correspond to the description according to the actual measured values. Measured at noon perpendicular to the sun 9.8.2021 50 degrees north. No-load voltage 21.8V. Short-circuit current 1.6A Voltage at load 16.8ohm 17.2V, ie power approximately 18W The active area of the panel is approximately 0.17 m2, which is about 6 times less than 1 m2. If the panel really had 50W, then the power of 1m2 should be 300W / 1m2 and the efficiency of the panel would have to be 30%, which is nonsense. I believe that the power of the panel in really optimal conditions is max 25W with an efficiency of about 16-17%. When the panel heats up with the sun, the performance decreases slightly. If the manufacturer declares the panel as 50W and calculates this value as the product of the no-load voltage times the short-circuit current, it is a disappointment.

It reads how many errors there are, but can't figure out exactly what they are. You will probably have to pay some additional license fee. But maybe I'm doing something wrong, which is not a frequent occurrence for me.

Jedna ze dvou baterek skoro úplně vybitá, druhá totálně mrtvá. Original nabíječka ji vůbec nevidí. Po oživení baterky z externího laboratorního zdroje se baterka již chytla. Jak bude však po podbití fungovat netuším.

The scooter came soon from the Czech warehouse, nicely packed, I was just surprised that when the box was opened, the lights on the still folded scooter were shining inside ... I don't understand which moula packed it :-). After assembling the scooter and tightening a few loose screws, loosening and fixing the brake levers and the control panel with the display in the ideal position, adjusting the headlights so that they do not shine into the treetops, the scooter was assembled in all its beauty. One screw was missing on the sleeve that secures the handlebars, tomorrow I have to buy it and tighten the sleeve with the other screw. So for now, satisfaction, the scooter is charging, so far everything seems to be working as it should. Tomorrow will be the first ride, so I'll test the engines, brakes and control unit. I also ordered a compatible saddle for this scooter. Although some comments from the dealer did not recommend the installation of a steering damper, I still have information from people who deal with scooter tuning that amateur-made installation with a universal steering damper allows safer driving, especially at speeds above 60km / h. So I will try to get a silencer somewhere and install it, it's a pity that even with the assembly of the original silencer it is not possible to order it directly on this scooter somewhere.

Lâmpada desinfetante germicida UV-C de luz LED 40W E27 130 lâmpada de desinfecção UV
US$21.84 US$22.99

Q: I have two measuring instruments. One indicates UV-B + UVB-C and the other only UV-C. Both devices show an absolute zero even in the immediate vicinity of this bulb. The response to solar radiation is perfectly fine for both meters. Even uranium glass does not emit the characteristic green light under this glass. Conversely, when I illuminate a normal UV-A LED on an unconnected bulb, the individual chips glow brightly green, indicating a luminescent layer on these LEDs that should not be on the UV-C. Another thing the price of a light bulb is slowly comparable to the price of a real single !!! UV-C LEDs. Please make the conclusion for yourself. Or someone will give me an acceptable explanation.

Ladys 10kHz- 1MHz jQuery191019277699710928276_1605805351625?

Bon produit. Quelques bizarreries sur l'ensemble de la plage avec des zones où la réponse est particulière. Après contrôle au générateur, la précision en fréquence est parfaite, la précision en niveau est (+/-) 7db, ce qui est tout à fait agréable à la vue de l'étendue du spectre. Bonus pour l'accès à 10kHz-1MHz pour lequel je n'avais pas de récepteur. Je recommande !

Q: Why, when I shine from a millimeter distance on a UVB-C detector, does the detector show me absolute zero? Is not the device equipped with cheap UV LEDs with a wavelength of 390 nm, so it is completely unsuitable for the destruction of bacteria and viruses?

perguntado por Ladys sobre 2020-05-21 01:59:30

Oblivion This item's ultraviolet wavelength is 270~280nm. It is suitable for the destruction of bacteria and viruses.

Q: So what's the laser there? 808, or 940nm. Apparently they can't be both. If the 808nm animals escape and the night telescope is useless. the only good choice is 940nm or more. Why this information is missing from almost all night telescopes
