Stabilizer Issue need the Explanation

I have a stabilizer,which take the input current 160 -270V and gives the output 200 - 240 V,how the stabilizer behave if Input is 1 - 159 V and and if 241 and above ,Will it pass the current which is not under their range to the connected devices how will it behave and what are the implecation of the connected devices?

Re: Stabilizer Issue need the Explanation

It depends on stablizer design. If the designer has implemented under/overvoltage, the stabilizer will simply turn off the output power.
If the stabilizer doesnt have undervoltage protection then if the input voltage decrease below 160V the output voltage will decrease below 200V proportionaly, till the control circuit is able to engerize the relays (around 90volts) and turn off.
Similarly if it doesnt have overvoltage protection then if the input voltage increases beyond 270, the output voltage will increase beyond 240 till either the output fuse is burnt, load damaged or stabilizer itself burnt.

Its simple, just see principe of transformator with many output taps.

Control unit, can be µC monitor input voltage and switch between output taps according to input voltage, so that output voltage always be 240V.

Its good to use fast switching relays for this purpose, to avoid some unwanted situations on consumer devices.
