UPS 800 Watt

Uninterruptible Power Supply UPS acts like a battery. It is an uninterruptible power supply that has a backup power inside the machine. makes us use the computer continuously Even in the event of a power outage Uninterruptible power supply UPS will act to help adjust the voltage to normal levels after a power outage UPS will help us use it for a while. so that we have time to deal with the work files Save data or turn off the computer. where the various devices will not be damaged

which is a great feature of a good power supply It works by converting alternating current or AC to direct current or DC and storing it as some backup power. At the time of the unexpected incident The backup power system will work immediately. Allows power to be supplied to the computer. or our electrical equipment

How to choose an uninterruptible power supply UPS
When choosing an uninterruptible power supply (UPS), it is very important to choose the one that best meets your needs. Therefore, it is necessary to know how to choose the correct one, which "watts (Watt: W)" is another important thing in the purchase of a UPS power supply, it is necessary to have a device or electrical appliances checked. to be used with uninterruptible power supplies That how much power is used, such as a desktop computer. will use about 300 - 500 watts of electricity, etc.

After checking the power of the device Next is to check the power of the appropriate UPS power supply. It usually appears with two values: "Appearing power" is expressed as "Volt x Ampere = VA", e.g. 1000VA. The longer the time it takes to back up the power. The second value is "Actual power" is measured in "Watts (Watt: W)", such as 550W. This value indicates how much power the peripheral device can handle.

The higher the VA value of the UPS, the longer it can back up power. In fact, there is another factor that must be examined. The amount of electrical power consumption (W) of electronic devices or electrical appliances that will be used. Because if the use is very close to the actual power of the uninterruptible power supply. For example, a 1000VA/550W UPS, used with a computer with a power of 300W, may be able to provide full power for 5 - 10 minutes, but if a computer uses 450W of power, it may be reduced to 3 - 5 minutes

Criteria for choosing a UPS

What is the power size (VA) used by these types of electrical equipment?
The power of the connected load It should not be higher than 80% of the UPS power. In other words, the UPS should be larger than the total power of the load. to reserve in case of Overload

Calculating the right size of UPS for electrical equipment Please do as follows:

• Gather a list of all the electrical equipment that will be connected to the UPS system, such as computers, monitors, modems, scanners, and other essential devices.
• See how many watts or how many VA electrical devices consume. Each type of electrical equipment has a label showing the power rating (Nameplate) at the end of the machine (this label will display voltage information. and electric current)
• Calculate the VA by multiplying the Volt and Amps values ​​together.
• If the label displays electrical equipment information in terms of electrical power in watts (Watt-W), convert it back to the VA value by multiplying the wattage value by 1.4.
• Include the VA or Watt values ​​of all electrical equipment listed to be connected to the UPS system.
• Choose a suitable UPS by dividing the value of 0.8.
• For example, calculate the connected electrical equipment 240Watt, calculate 240/0.8 = 300, so choose UPS with more than 300Watt power.

How long do you want the UPS to provide standby power? (Backup Time)
If you want to have more backup time than usual, choose UPS. High-Rate battery models can provide approximately 20% longer backup time (depending on the electrical equipment used).
