Due to our flakey local power supply I'm quite au fait with setting up UPS units for computers. However my wife is setting up a tropical aquarium and would like a similar level of protection for her fish.
Total equipment load is miniscule compared to computer equipment.
75W Heater 18W Flourescent tube 6W Filter pump 5W Air pump----------------------
104W TOTALI'm assuming the power factor of the heater will be similar to an incandescent bulb i.e. approaching unity (1) but the pumps are presumably inductive mechanisms so would I be looking at 0.75 or worse? Flourescent tubes would normally have a PF of 0.85-0.9.
Ideally I'd like at least a couple of hours backup since we rarely have outages long than this, what sort of VA rating should I be looking for?
