By what characteristics pick up the UPS (UPS)?January 30, 2018
Choosing an uninterruptible power supply, it is worth repelling from such models, which are able to give the best protective effect, while requiring minimal costs. The range of this equipment is available at the following link - fostero.ua.
If it is conditional to divide, then all UPS models are divided into three categories, depending on the level of protection:
•basic protection. Such devices allow to avoid the most basic network instabilities. A single pulse with a large amplitude but a short duration is one such case, which is a thunderstorm discharge or sparking poor-quality contacts in electrical wiring, as well as daily voltage fluctuations or periodic power cuts are one of the most common problems that the basic protection of the UPS solves . This category includes offline UPS and line-interactive view sources;
•improved security. Such devices are capable of filtering out radio frequency or electromagnetic interference in a network. At the same time, it is possible to adjust the input voltage in wide ranges (for which it is not necessary to switch to batteries), due to the presence of an automatic voltage regulator (AVR). This category of equipment also includes a linear-interactive UPS, with an approximated sinusoid and improved characteristics;
•absolute protection. Choosing this type of uninterruptible power supply you no longer have to deal with all sorts of problems in the mains. In addition, such a device is capable of adjusting the power factor and the shape of the output voltage, in consequence of which the operating life of devices connected to the UPS will be extended. This category includes the following devices: UPS double power conversion, zero switching time.
When choosing an uninterruptible power supply, you should consider the following technical parameters of the device:
• what technology and shape the output voltage has;
• power characteristics of the device;
• for how long the UPS is able to work offline and from battery support.
In addition, important parameters are also the following: whether there is an interface port and software that allows you to monitor the status of the network and the UPS; Can I connect external battery packs and increase battery life; is there an electronic or manual bypass; how long the device is able to switch to battery operation.
In addition, when choosing an uninterruptible power supply, the parameters of the electrical network and what technical characteristics the equipment that needs to be protected from problems has to be taken into account.
