What are the optimal, specific power requirements (volts/amps) for direct wiring this via mini-USB?
1891914
Per Aeotec Support: To power Multisensor by USB, the optimal volts/amps is 5V, 38mA.

You just use a standard USB connection. I honestly don't know the specifics, but I'm going to put these in my hallways and I'm putting an outlet with hi power usb outlets on it

Hey, I bought SEVERAL of these - these definitely work great AND ALSO VERY IMPORTANT! ONE sensor would NOT WORK! It was because of the USB cable was NOT THE RIGHT ONE!!So I bought these exact ones off Amazon:USB Adapter = http://tinyurl.com/nfx89oz USB Cable for the sensor: http://tinyurl.com/p5an5hc These are the ones that work great for a few yrs for me. That darn USB Cable though! I had one that looks the same but it was actually different! It plugged in and powered the device, but TWO of the sensors did NOT work correctly! IT was the cable! man, took me HOURS of troubleshooting! I ordered one of these USB cables and BAM worked instantly!

I'm not sure, as I only have a USB 2.0 hub... I dont see why not. Still 5 volts I believe and receiving I.R. Is probably low voltage. G.L.

The standard is 500mA for USB 2.0 and 900mA for USB 3.0. Do the math, and you'll see that the power supply doesn't cut it for 24 USB 2.0 and 4 USB 3.0 ports. 24 x 500mA = 12A 4 x 900mA = 3.6A The power supply would need to be 15.6A at 5V. Since the power supply is only 4A at 5V, you're only going to be able to power four USB 3.0 devices (900mA x 4 = 3.6A) OR eight USB 2.0 devices (500mA x 8 = 4A). Perhaps Manhattan should do what Anker does and use a 12V adapter and whatever they do to undervolt/cut down their USB 3.0 9-port hub to 5V per port (that thing comes with a 12V, 5A power adapter! The brick is almost as big as most laptop power bricks!) Using the formula of Volts x Amps = Watts (5V x 15.6A = 78W), we can conclude that at 12V, only 6.5A would be needed (12V x 6.5A = 78W). It's a shame, though, as a 28-port USB hub is cool as all hell, but in practice, it doesn't work right unless you're using all self-powered devices (devices that have their own power adapters).

You'll have to use either a Thin-ITX board with internal voltage regulation, or a picoPSU unit. Both require external power bricks.

I suggest you buy a converter which supports power at least 3 times larger than what you really need, this will make you less trouble. Thus for your PS, 500W seems good enough.

Hi Michael - thanks for the interest in Orb. The power supply for the Mini T rated at 12v / 3 amps. Hope this helps - thanks again for the email and let us know if you have any more questions.

There's not enough power (amps) through USB, it needs to be a self powered drive but yes it can hook up to the USB.Also must be formatted in FAT32.

Look up the "AmazonBasics USB 2.0 A-Male to Mini-B Cable - 6 Feet" and any USB wall charger that gives adequate current (there are many now that are > 1 amp at 5v)

I use a multi voltage adapter from Wal-Mart. It works great. Just have to make sure to correctly set the voltage and plug the correct adapter onto the connecting lead. The adapter sells for around $14.00 and can be bought with or without a USB socket.

From the spec sheet...USB Output: DC 5.2V 2AmpUSB Input: AC 125V 50/60Hz 350mA

Do you mean the voltage output? If so, it outputs USB voltage (5 V DC at a max of 2 amps).

It depends on what you're feeding it with. Recall that voltatage x current = power. The max peak power of the device is 3000W. If you're using an alternator, go with a 200A fuse--at 14.4V bus voltage, your current will be 208A. Otherwise, go with a 250A for 12V. The absolute max tolerable current is 285A for the 10.5V minimum input, so anything bigger than that is a waste.

Usb is 5Volts with .5A maximum draw. My multimeter won't even measure the current it's drawing so I'm not sure the exact wattage. So by using the above figures... 2.5 watts maximum although I guarantee it's definitely less than that. Hope that helps. The actual unit itself has no power listing so that's all I can figure for that.

The power adapter it comes with plugs into the wall and takes 100-240VAC. It provides 5VDC at 2.6A. This means you could power up to 5 devices at the maximum rated USB power (500mA each). It should be more than enough for standard peripherals (keyboard, mouse, printer, webcam, etc.)

This hub is underpowered by almost 45%. USB 2.0 ports should be able to pull 500mA, so with 7 ports the AC adapter should supply 3.5 Amps. It only delivers 2. Almost every powered hub on the market seems to be similarly underpowered.

Get the voltage and polarity right and you should be ok. Just be careful not to fry it.

Correct Only 5VDC USB charge outputs most Laptops need at least 18 to 24VDC
