I would like to know which UPS can run a printer (50 W) for 8 hrs without charging. I have been trying many different models and i am not sure if I am doing the right way. 1000 VA Smart UPS gives me around 4 hrs. So is 2000 VA the best choice I have to double the backup time?
Or is there another series of UPS intended for long hours of back up run time for mobile solutions ?
If you navigate to apc.com and select your Country
Then navigate to:
Support > Resources & tools > Tools & selectors
Then select “UPS Selector”
If you enter the expected load the tool will recommend a solution.
What you probably want is a Smart-UPS with the extended runtime (XL) option and a few battery boxes.
If this is a laser printer, it's worth considering that the inrush current may exceed the inverter's capabilities in even a fairly large UPS.
There are some Back-UPS products with limited extended runtime capability. You would have to be sure that your printer is OK with modified sine wave power if you chose a Back-UPS model.
