How many time have I to wait since the sinuswave of the electrical voltage has stabilized at ac output?
This morning I used acc300/b300 as an ups for my sonography machine the second time…
First I power on acc300/b300 and in very short time, i think about 10 til 15 sec. later I also powered on my sonography machine. The sonography machine started, but there was an unround fan noise. So I decided to shut down my sonogrpahy machine. With the restart of the sonography machine the noise has disappeared. The sonography machine has never done this befor!
How long have I to wait? Your opinon or experience? Maybe messurements?
thanks for your question and sorry about my indifferent description.
Yes, this noise was from my ultrasound machine. I think it was from one of his fans. Today all is like every day, no noise. Maybe bcause I waited some minutes after startup of the BLUETTI ac300. and about 3 minutes later I started my ultrasound machine. All works fine today.
