سؤال: Is it usable with 8 x 1.2V NI-MH batteries ?

السؤال بواسطة pesoft على 2017-12-10 05:40:40

Craig Ijust use the AA batteries. Plus I've only had it a couple of days so they may work. But the batteries may not last as long.

سؤال: I suppose is provided without a power supply. Which power supply 48V is suitable?

السؤال بواسطة algufo على 2020-09-16 04:28:38

pesoft No power supply provided and power supply depends on what you want to power, I use it for example for passive injection splitter using 12V for non PoE cameras.

سؤال: someone explain to me how 20W can be produced with only 12V/600mA P=UxI so P = 7,2W

السؤال بواسطة pesoft على 2019-03-17 03:53:57

14tek ---300mA Nominal--- Not only that but 600mA is "MAX" Nominal is prob. 1/2 of that. 300mA So the actual working power is **3.6 Watts** at best FALSE SPECS!!! The Chinese really think we're Stupid!.......................

drhill 10.000 amps is the maximum short circuit handling. I asume you ca order from 25A to 125A. Indeed is not too clear. Only US Electrical Engineers understand those terms.

سؤال: Those guys has serious maths issues because 12V*3A = 36W not 100W

notyoung This panel is about 60% of the surface area of a standard solar panel so, at best, it MIGHT deliver 60 watts. All too often I see electrically ignorant people trying to use the Voc times the Isc to figure solar power and calling it "peak" but those values can NEVER occur together. Voc is the open circuit voltage and Isc is the short circuit current which can NOT happen at the same time. The true output of a solar panel is Vmp times Imp which are the values at the Maximum Power point of that panel. Unfortunately, their ignorance doesn't let them know that they are advertising lies. Same concept applies to the power rating of inverters; Examples: https://www.banggood.com/4000W-12V24V-DC-to-110V220V-AC-Solar-Power-Inverter-LED-Modified-Sine-Wave-Converter-Black-p-1287105.html Q: Can I use for power a little refrigerator? A: Please Ensure the Rated Power(550W) is Higher than the electric appliance you wanna apply to.

سؤال: how can this cable be USB to TTL, I see micro-usb at the end of it and not usual 4 pins connector ?

السؤال بواسطة pesoft على 2019-03-10 06:09:32

rrwakc Some devices use standard USB connector for charging but haver regular UART ports on data pins. Usually TX on D+ and RX on D- It enables you to have same port even on devices that don't have USB support or don't need crystal for their operation.

Jaquen I think that the power supply with a USB interface is connected with a cable. It is not because this module has a USB interface. The picture description is incorrect.

pesoft I guess the pins on the right side of the PCB are here just for that.

pesoft first of all the TDA7492P is not supposed to be 50W+50W but 25W + 25W continuous output power at THD = 10% with VCC = 20 V and RL = 8 ohms, max current 4.2A, minimum TDA7292P voltage is 8V, DC-DC converter cannot provide enought power from 3.7V you will have to serialize multiple 3.7V, look at the voltage and amps sheet in the decsription.
