The selection of UPS and power devices suitable for IT is a difficult problem for the staff does not have much capacity is statically UPSthuc power and UPS. But when the company needs, the choice is UPS IT staff. These issues need to be addressed such as: Defending have 1 server, 1 switch, 1 router, it is appropriate to use UPS ... ..2 server, 1 printer, to save power, the UPS online or offline 30min

To help you choose UPS and power matching IT needs. www.suachuaups.net teaches you the order to calculate for themselves their needs.

According to the principle of conservation of energy, the power supply (UPS) must be greater than or equal load capacity. Therefore, we first need to calculate the total load capacity by:

     Make a list of equipment needed UPS protection.
     Determining the capacity of each device VA (if the device can not make power, we get voltage (Volt) multiplied by the current (Amp) for each item in the list will be capacity VA
     Calculate the total capacity of all VA facilities.
     To ensure some redundancy. Capacity should choose UPS capacity equal to or greater than the sum of 20% of devices.

In addition, there is one other factors affecting the choice of UPS power as:

     Nominal capacity on the device's maximum capacity if the device does not use the stock depleted energy, accessories, the actual capacity will be less. Usually UPS consumes only about 50% of nominal capacity, usually each with the tool manufacturer's calculations to determine the relative capacity of each user configuration.
     If UPS is the engine load or laser printer, or other device with large inrush currents, you should charge extra for UPS capacity to compensate for the energy spike when the device boots.
     Scalability equipment in a short time, hardware upgrades, server or retrofit new products often require a higher energy level than the old version. Therefore, you need to predict the demand for additional capacity in the short or medium term to choose appropriate UPS

Example: Select the UPS power for 1 server, 1 router, one switch:

Server: nominal capacity = 1000VA

Router: Nominal Capacity = 100VA

Switch: nominal capacity = 200VA

=> total load capacity = 1.300VA

Redundant UPS power gazetted 20% = 1,300 * 1.2 = 1.560VA.

=> Select the UPS capacity 2KVA.
