I can provide you with a definitive reply for the dilemma in title. Having said that, you have got an strange condition, and It truly is only attainable to invest concerning what else it may be. Could your non-pure sine wave UPS be answerable for the hurt?
Pure sine-wave inverter: No model we analyzed with this particular function could match the output, run situations, and surge-defense capabilities of our picks, but it could be beneficial in rare conditions, and we normally want it—particularly in designs missing AVR. All sine-wave inverters turn DC electrical power into AC energy, but a pure sine-wave inverter can develop electrical waveforms as apparent and sleek because the AC power from any wall outlet, While modified (or simulated) sine-wave inverters produce choppier waveforms.
However, there isn't a brilliant rapid rule-of-thumb calculation for figuring out the runtime like there is for pinpointing the necessary minimal VA. The truth is, It is really this kind of an enormous inconvenience to dig up the required information and facts (Particularly the effectiveness ranking), that It can be much more expedient to work with company estimate tables (which we've located to generally be to the conservative facet anyways).
