How many watt UPS is Required for a 5000 Lumens Projector?

Answer 1

Not enough information is provided by the question, however, it is simple enough to determine the wattage required for the projector with a multimeter. Measure the voltage (120V likely in the US) and current with the multimeter. Then multiply them. For example, if you measure 120 volts and 5 amps, then 120V x 5A = 600 watts. Another device you can find on Amazon is the "KILL A WATT" that your can plug the projector into and it will directly measure the watts or volt-amps of the projector. Now it gets a bit more complicated. If the lamp in the projector is a "high intensity discharge" type lamp (Mercury vapor, for example), then the UPS you want must be "fast transfer" so the projector (and lamp) doesn't lose power for any appreciable amount of time. The "fast transfer" UPS's are significantly more expensive than the simple backup battery packs that Amazon sells for less than $100. That type will work with a lamp that is an incandescent type.
