How to Choose an Uninterruptible Power Supply – Buying Guide
First of all, we must know the importance and points on how to choose an Uninterruptible Power supply then we tackled the products after the reviews. Check this out!
Choose the type of Power supply method
There are various types of UPS or Uninterruptible Power supply, first is a commercial power supply, second is the interactive power supply and inverter power supply. Hence, you must choose a product that is suitable for your convenience, as the amount of power consumed and how it changes during the power interruption.
Choose for commercial use power supply
For a home personal computer, we recommend the always-on-the-shelf power supply because of its low price at the same time low consumption, and ease of purchase. The uninterruptible power supply of the standard commercial power supply system is simple to purchase because it is less expensive than other power supply products.
In a situation where there is no problem with the commercial power supply, the Alternative current or AC is sent directly to the connected device, and the battery is charged using a rectifier.
Choose with line interactive power supply
Also, if you want to ensure server protection and voltage stability even at home personal computer, then you must choose with line interactive power supply or automatic voltage regulator(AVR) built-in, which not only switches from a commercial power supply to a UPS in the event of power interruption but also stabilize the voltage during standard operation.
Since instantaneous interruption is inevitable, it is not suitable for environments where the system is down, such as data centers. However, since it has sufficient performance and the product is not so expensive, and yet it is recommended for excellent performance.
Choose has a continuous inverter power-feeding system
If you always operate using a server and want to switch from a commercial power supply to an uninterruptible power supply without instantaneous interruption in the event of power failure, the always-on inverter power supply system is advisable.
Furthermore, in a continuous inverter power supply system, the alternating current flowing from the commercial power supply is converted to direct current with a rectifier, and the battery is charged, while the frequency inverter always generates.
Choose the waveform power supply output
Here there are two types of uninterruptible power supply output waveforms, sine wave, and rectangular wave. Sine wave UPS is advisable because it is compatible with the PC server. Since the square wave type is cheap and easy to purchase, be aware that it cannot be used with a PC server that has built-in parts.
Choose the rated output battery capacity
You must also check the number of devices you want to connect like computers and servers, and then you select a UPS with a battery with a rated output capacity that can supply enough power.
Furthermore, when multiple PCs and servers in used, the rated output capacity is required more in proportion to the number of devices. Take note that the Uninterruptible Power supply or UPS function cannot be fully used if the PC or server is connected beyond the output capacity.
