You use commercial grade power systems.

1.) Natural gas generator with voltage regulators for 3 phase power
2.) Phase monitors to stabilize the power to the batteries
3.) A series of commercial turck batteries to keep steady flow of power to the building

Usually the generator is at max power for the building at 60% capacity to keep it running cooler. The batteries maintain power for 20-60 minutes without the generator. The generator powers up. The phase monitors will not release the generator power until it is proper phase and voltage levels to prevent problems. These systems can cost $100,000+ to install. They require monthly testing and repairs. You replace batteries every 3-4 years.

WOW so how come when the power does go out it takes hours to days to get it back on line ???
WORK HARDER ON THAT OK? !

Thank You Zozio.

Originally posted by: Unknown he efficiency of the HPU-4M530-PU is very bad. During small load Hiper creates an efficiency of 75,7% with this model straight times. Under full load it becomes not much better and creates straight times 79,2%. That is no longer up-to-date.

According to packing print it concerns with this power pack the version 3 of this power pack. The result is the sadder.

Result: For a manufacturer, that builds its power packs, the test result is proper fatal. Tensions outside of the specification and bad efficiency do not speak for the manufacturer Hiper. For this reason we advise against urgently of the purchase of the HPU-4M530-PU


The Hiper which the French E-Commerce reported low fail rates for failed the test so I rest my case all it tells me is those with low fail rates under perform under load possibly to keep them cooler? I dont disagree that ANtec has problems with the later models but Tegan and Enermax are certainly good PSU's that maintain stated voltage levels under load. We need to watch that site to see how the Enermax and Tegans do.
