Is the voltage stabilizer suitable for a monoblock?

Question

Do it yourself

Is the Uniel U-ARS-1000/1 automatic voltage regulator suitable for connecting an iMac 5K monoblock to it?
I read in the instructions for the stabilizer:
“The device is designed to work with equipment sensitive to voltage drops, such as computers, monitors, printers, scanners, TVs, stereos and other equipment for sound and video”
“The device cannot be used with equipment such as a refrigerator , automatic tools, air conditioners and other devices equipped with an AC motor”
Then I looked that the plug on the iMac indicated 16A 250V ~, and the site indicated:
“Power requirements. Line voltage: 100 to 240 V~. Frequency: 50 to 60 Hz, single-phase current.
The search for "single-phase current" is the Wikipedia article "alternating current", but it also notes: "Although alternating current is often translated into English as alternating current, these terms are not equivalent. The term alternating current (AC) in the narrow sense means a sinusoidal current, in the broad sense - a periodic alternating current (that is, a periodic bidirectional current). Symbol on electrical appliances: ∼ or ≈ ”
https://ru.wikipedia.org/wiki/Alternating_current
All this is very confusing.

Answer 1

A note about engines means that the output of the stabilizer is not a real sinusoid, but a ladder close to it.
For switching power supplies, this does not matter, but motors and transformers with such a current cannot work.
Such a stabilizer is suitable for any modern computer and other modern digital device.
They all use switching power supplies.
PS From such a stabilizer for a computer, there is little sense: for a power supply, the operating voltage is from 100 to 250 volts. It is much better to protect the whole house / apartment with a voltage relay in case of a zero drop (in this case, 380 volts may be in the network.)

Answer 2

A strange choice, to put cheap non-name shit on an expensive candy bar.
Take a normal uninterruptible power supply with a voltage stabilization function
such as APC Back-UPS 800 VA
is not much more expensive but much more useful. And protects from jumps and from sudden disappearance.
