Room UPS power purchase program
Select UPS power brand according to economic capabilityThe choice of brand is divided into domestic and imported two, as domestic enterprises, although imports than domestic product does have the advantage, but because of the economic capacity constraints, and the development of national economy and technology support, it is recommended to select domestic. Because in recent years, domestic UPS manufacturers still have considerable improvement in technology. On the other hand, the choice of domestic products in the aftermarket is more convenient. For example, Sored UPS power, all products are normal three years warranty. If you really need to choose imports, you should also choose more well-known manufacturers, but once the failure of imported UPS, often can not be repaired in a timely manner, long-term use can not be used.
Determine the power of the UPS power sourceAccording to the computer room and the load equipment of the total amount of electricity multiplied by the industry safety factor ~1.2 or so, it is almost UPS power supply.
From the principle of UPS power to choose backup or online?The choice of On-line UPS power or backup UPS power supply should be based on the needs of microcomputer equipment and economic conditions. If the economic condition is good, optional on-line UPS power supply; if the economic condition is poor, but not affect the normal operation of the computer, backup UPS power supply can also be selected. In the use of back-up UPS power supply, special attention should be paid to the switching time of the power supply. The switching time mainly depends on the switching time of the UPS power supply and the switching time of the microcomputer. If the selection is not correct, the computer will stop when the power supply failure, and can not play the role of power supply protection.
Also need to remind is that in the choice of imported brands should pay attention to some details of the problem, usually imported products import and output wiring mode is different from China, in the selection should pay attention to improve methods. Simply put, our single-phase power supply is left, zero, right, fire, and the United States is the left, right, zero. In addition, we also notice that the American Standard plug style and China are not the same. In the United States national standard plug and socket to China's national standard plug and socket, should pay attention to the internal relationship of the connector, can not simply adjust the line.
