[QUOTE="Timo Ulkuniemi, post: 104683, member: 1978"] Re: X32 Discussion Hello The nature of fulltime inverter-running UPS is such, that if it clears the "pull the plug - test" it will also survive all kinds of brownouts etc as long the battery has some juice in it. The way the unit is built is basically : 120/240VAC into battery charger - 12-48V DC into battery - inverter - 120/240VAC out. Think of it this way - when power gets cut off completely, the UPS relies on it´s battery only - the runtime is usually included in specs - say i.e. 30 minutes for your load. No charging of battery is done and after 30 minutes you are out of power. In case of brownout the charger may still provide some juice for the battery - thus extending runtime. So total blackout is worst scenario and everything else will be easier. Overvoltage protection is another story - but a well built UPS will take care of that, too. So for what we need the UPS in our X32 setups - pulling cable off wall socket is THE test , if the unit has no test button. If power goes off completely for 5 to10 seconds, or more, the show will be stopped anyway - so booting of desk should be no issue - but if the show stops because our X32 has to reboot because of freezer-compressor in the kitchen just kicked in and sent a spike or drop into line.... - then we will look very very bad with our desk rebooting, while otherwise nobody had ever noticed anything in sound or lights.
