Technical Specifications
(There is nothing to translate, as this is an empty HTML tag with a non-visible space.) Linear-interactive uninterruptible power supply (UPS) sources SNR, LID-XXXX series, occupy an intermediate position between simple, inexpensive backup sources ("Off-Line") and efficient, expensive UPSs with double conversion of energy ("On-Line"). The main difference between the LID-XXXX series UPS and backup power sources ("Off-Line") is that it is capable of providing normal power to the load when there are deviations in the parameters of the mains voltage, without switching to battery mode, which in turn has a positive effect on the service life of the built-in UPS batteries.
The LID series UPS is equipped with a "cold start" function, which allows the UPS to be forcibly turned on in the absence of mains voltage, as well as an "auto-start" function, which allows the load to be automatically powered up when the mains voltage is restored, without the need for additional manipulations.
The built-in USB port allows for monitoring the main parameters of the UPS from a computer, as well as performing a proper shutdown in automatic mode. In addition, the UPS is equipped with a multifunctional LCD display with backlight, which displays current information about the UPS operation. UPSs of this series provide output voltage with an approximated sine wave and are mainly designed for connecting equipment with pulse power sources: personal computers, LAN nodes, and other electronic devices equipped with similar power sources, which, in turn, are practically insensitive to the shape of the power supply sine wave and its short-term interruptions (switching to battery mode).The advantage of line-interactive UPS is their relative simplicity and reliability, lower cost compared to "On-line" solutions, and high efficiency in "from grid" mode. The disadvantages include a slight delay in switching (a few milliseconds) to "battery mode" and a stepped (less smooth compared to "On-line") regulation of the output voltage.
