Hi,
Can you recommend any power supply that can perfectly work to supply enough power for the Jetson AGX Orin device? It can work on 12V-3A and 20V-4.5A.
I am using just a USB cable to supply power to Raspberry Pi from my laptop.
Hi @romyull,
I’m not entirely sure if your question refers to the power supply for the Otii instrument or directly for your device.
If you need to power your device, the Otii Ace Pro can supply up to 25V/5A while simultaneously measuring current, voltage, and power levels. The datasheet provides more details.
If you’re asking about an additional DC adapter power supply for the Otii instrument itself due to insufficient power from your computer’s port, we recommend theTRH70A180-11E03 VI from Cincon Electronics Co. LTD. Find more info in the FAQ section of the Otii Ace Pro.
I hope this helps!

Hi,
Thank you so much for the reply.
I was trying to power the Raspberry Pi 5 using Otii Ace Pro. Used a USB to power it from my laptop. The device turns off while Raspberry Pi is about to turn on.
I want to measure the power utilization of Nvidia Jetson AGX Orin. In both cases, I think I need a more powerful power source. So, I wanted to have an external power source like TRH70A180-11E03 VI.
In this setup case, adding an external power source is highly recommended. A couple of days ago, we shared a summary of a study from the IT University of Copenhagen that performed an evaluation somewhat similar to the one you are looking to validate. It could possibly be a good reference for you.

I bought this one(TRH70A180-11E03). But it can not supply enough power to turn on the Nvidia Jetson Orin. I don’t know why; I selected 12v 3A, 1v 3A even 18v 3A. Nothing changes.
Hi,
What Orin version are you using?
From the datasheet, AGX Orin is the most power hungry in the Orin family, it maxes at 60W and Ace max maximum output power, peak, 50W.
If you keep below 50W, it should not be any problem in your setup.
Have you verified that Ace is connected to the external power supply?
Check Monitor (Ctrl-M) and the VDC value, this should be the DC adapter voltage if all is good.
Best regards,

Hi,
I am using Jetson AGX Orin 32GB. The DC power supply can produce up to 70W. I am trying to use as much configuration as possible. The monitor values are shown in this image.
No configuration can turn on the jetson. I am not sure if it is the issue with the type c cable that I am using to power up Jetson. This cable works fine for Raspberry Pi 5.
Otii Ace will limit power output to maximum 50W, do you know how high the startup current is?
One other option is to youse the Ace in in-line mode, if the power out from Ace is not high enough.
You can see the use case here:
In the picture, the battery will then be the connection to the other power supply.
Ace will only measure, not power in this mode.
Always make sure that it is in in-line mode before you turn on the power, otherwise it will be the external power + Ace power for your Jetson.
Best regards,
Björn
Thank you so much for the information.
