■ Features of CPTT Digital UPS ( 2 )
★ Excellent performance of UPS
Adopting the most advanced high-frequency carrier technology to improve output accuracy, reduce product and weight, and applying the latest loop design technology to minimize switching power loss, thus greatly improving the overall efficiency, having extremely high power factor, not generating harmonic interference to commercial power, and reducing power loss.
★ Humanized Intelligent LCD Panel Design
UPS has a humanized indicator panel, which can display all the working conditions of UPS before it leaves, and messages such as commercial power, battery, output, load and in-machine status can be displayed through the panel liquid crystal, greatly facilitating operation and users.
★ Super intelligent power management software
Remote monitoring is implemented through RS232 interface, which provides detailed information about commercial power, battery, output load and in-machine status to the outside, and has the functions of system self - test, time switch machine and various state detection and alarm functions, thus becoming a truly intelligent UPS.
