ASIAIR PRO power supply issue

lukfer

A few days ago i purchase an ASIAIR Pro that is powered with an external power supply from ZWo (12v 5A).
When i power my camera (ASI 1600 MMC) whith the power output from the ASIAIR PRO , red led in the camera lights very dimm .
When switch on the cooler in the ASIAIR app, led in camera turns off.
If i use an external power supply for the camera, led is bright and cooler works fine.
Both things tried in an second camera, ASI 294 MC PRO, another external power supply (12v 3A) and the same result.
Seems like the ASIAIR PRO couldent supply suficient power to the cameras.
Any help is welcome.
Thanks in advance.

Hello, do you open PWM in the power management, pull down the voltage, can you cut a diagram to have a look

Hello
Cant find in asiair app nothing called power management, only switches to turn on/of every output under power output menu, but no information about voltage there.
Please show me how to find It.
Thanks.

I'm having the exact same issue with an ASI294MC Pro. I have tried with both the ZWO external power supply and a Celestron Powertank Lithium Pro without success.

asiair@zwo can you please suggest a solution?

Hi, I have the same camera, I just turned my system on to check mine,
My set up is working correctly, if i was to guess why others are having this type of issue, I would point my finger to the actual power supply.

Any news on this?

Loupy which power supply do you use (volts and amps)?

asiair@zwo

Plz check
#1 the power supply to the ASIAIR device,
#2 The DC output settings, turn on the 4 ports.

@asiair@zwo#42982 have already checked with two different power supplies and all DC outputs are ON. Today I also discovered that it won't power a single dew heater strap. How can we debug this?

I'm having the same issue: specifically insufficient current being supplied through the USB ports. My power supply is the Rockman 200 power station... 12V/5amps. Attempting to debug this, I tried a wall-wart power supply - same thing. I then connected the ASIAIR Pro running 1.5.1 (6.92) to a bench power supply configured for 12V/5amp and measured the draw. After booting the AAP and wifi established, it's drawing 0.30 amps. When I connect the ZWO ASI120MM Mini camera to any port, the current draw does not change. It should have. When I connect my cell phone to these same port, the current draw only slightly increases (approx 0.38 amps). The camera & cable works fine when connected to my laptop running PHD2 and I can loop just fine. I suspect there is something in the firmware that's limiting the current flow through the usb ports. FYI, my serial number is 34cac3b2. I think you may have a bad batch, or a serious firmware bug. I know many others are successfully running the same configurations successfully.

Please advise.

kjobcolorado If you are using a cooled camera, plz power supply it with the DC outputs. The only USB connection can not afford enough power.
