I have an Acer projector that I have connected to a UPS(800 VA) because there are frequent power outages in my area. When the projector is in standby mode, if there is a power outage, it is able to switch to UPS power instantaneously. However, when the projector is on(i.e when the lamp is on), in case of power cuts, it switches off and then switches back on within a second. This essentially defeats the whole purpose of connecting projector to the UPS. Why the projector is not able to switch to UPS power immediately when the projector lamp on? Does such abrupt switch off/on affect the lamp?
