this is type of dvr i make it
For what voltage (wanted output voltage, range of tolerable input voltages)?
For what current power / current?
What conditions does it to have to work under? Indoors, outdoors, under water, under hot conditions, in vacuum?
Your question is like: How to make a roof?

sag / swell voltage mitigate in power system for make dvr
A Sola constant voltage transformer will deliver a the same line voltage even if the input varies +15% -20% ... So a 120VAC is delivered even if the input mains is as low as 96VAC or as high as 138VAC.
That should be good for your DVR !
BTW a small Sola for a DVR should cost under $150 US or less and work all your life (no semiconductors to fail).
One other interesting thing about a Sola is if you overload it it will go into current limit mode a great feature to wind up a flywheel or charge a huge coil gun.
Er..., yep, ähem, ...Do you have some number related to some units? (preferentially some SI units).You know, it's quit a difference if we talk about 12V in/out with +/-10% in at 1A for your car stereo, or 100kV in/out with +/-50%in at 100A... (to be used in a life support application in high humidity and under high radiation)
Hey thats where my cousin exercises as an urban explorer of humid dark dank and dirty s___y sewers with surprisingly, the occasional high tension power line.
Sometimes I really think it is best not to answer to such incomplete requests.a) The user might never return anywayb) If noone answers he/she might actually realise that something is missing.
Philosophy of the incomplete, is an interesting pastime.
Theorising a newbie firstime didn't how to find the question again, so after a few days I would leave a nice note & link on their page or PM them but never got a returnee.
Surprisingly I get a Best Answer way out of the past now and then.
