Power Spike and Dip Protection
Does anyone know if there are systems out there that can deal with spikes and dips in the power supply, as most just seem to be just geared towards surges
Your help would be most appreciated
It depends what you want to achieve. A reasonably priced UPS will keep a LCD running for a few minutes, but will not ensure continued viewing during blackouts or brownouts. You can of course buy a professional UPS that can keep a server running for several hours, but it will cost more than the screen itself and they need large batteries. The real point of an AV UPS is to keep the cooling fan of a projector whirring so that the expensive bulb cools in a controlled way during the power loss. The cost of the UPS then needs to be weighed against the cost of the bulb. You may want to calculate the cost of exposure, that is the percentage chance of a blackout occuring multiplied by the cost of replacing a bulb. If that cost approaches or is higher than the cost of the UPS then it is worth thinking about.
You can maybe get a UPS with AVR function. This way, your AC output from the UPS will be stable. And you do not have to worry about the fluctuations in the voltage and spikes.
