UPS-SPF power frequency, online, and uninterrupted power supply (single inlet)
Uninterruptible power supply
General Product description
The SPF series is the third generation of power frequency, online, and intelligent UPS which is designed especially for powering network computer rooms, small intelligent equipment, measuring devices, industrial automation equipment, and precision instrument in industrials like finance, communication, insurance, transportation, tax, military, stock, energy, education, government, enterprises and so on. The SPF series is especially suitable to provide power protection for extreme circumstances of power grid, as well as enterprise servers, small & medium sized local area network, small computer rooms and other delicate electronic instruments. The SPF series puts stability above everything. You can count on it.
Product features
High reliability
Adopt multi feedback control methods like instant control and valid value control to achieve high dynamic adjustment to decrease the waveform distortion
Fully meet the requirement of sweeping the load from 0 to 100% without switching to bypass-circuit mode and ensure the stability and reliability of outputs.
Adopt the technology of dual switch and static electronic bypass circuit to truly attain switch time of zero.
Very broad input voltage and frequency range to decrease the chance of battery discharge and extend the life span of the battery
Powerful function of cold boot makes it possible to start up in full load when there is no alternating current, which is practical for customers with specific requirements for emergency handling.
The system is equipped with multi-protection and alarms functions like under-voltage and overvoltage protection in input and output, input surge protection, phase sequence protection, over charge and over discharge protection of battery, output overload short-circuited protection and high temperature protection.
The system uses SPWM pulse width modulation technology, IGBT power module and input-output-separating transformer; preventing the UPS output from the interference of the power grid, and ultimately providing low distortion and pure sinusoidal power supply.
