Abstract: A protection system for computer equipment providing a controlled power source and environment to a plurality of remote locations. An A/C supply line charges a D/C supply which is inverted to provide A/C power to the remotely located equipment which is thereby isolated from power outages and supply line fluctuations. An environmental control system is further provided including a series of filters disposed in duct work to condition supply air, whereby it is refrigerated with a Peltier-effect heat pump driven by the D/C supply or a mechanical heat pump driven by an A/C power source, in the case of very large units. A plurality of individualized supply ducts from the main duct deliver the treated air to exhaust fan ports or convection cooling openings of respective desired electronic apparatus which may include a plurality of individual personal computers and/or peripials.
