Product introduction:
EK900 series UPS is a kind of double-conversion online design, single-in and single-out high power density miniaturized uninterruptible power supply equipment launched by Powerware. The product has high efficiency and high reliability, and provides reliable and high-quality AC power for your equipment. This series of UPS can be divided into two categories: standard type and long-term type according to the different configurations of the battery part of the machine.
Performance characteristics:
1.Advanced working mode
Double-conversion on-line design is adopted to ensure that the output of UPS is a pure sine wave power supply with frequency tracking, phase-locking and voltage stabilization, filtering out noise, and not being interfered by grid fluctuations; output zero switching time, meeting the high standard requirements of precision equipment for power supply ;
Using input power factor correction (PFC) technology, the input power factor is higher than 0.98;
With 50Hz/60Hz power system adaptive function;
The output voltage can be set to 208V/220V/230V/240V;
2.High reliability of the whole system
DSP digital control is used to directly generate high frequency pulse width modulation wave (SPWM) to control the UPS inverter, which simplifies the control circuit of the UPS, improves the digital control technology of the UPSt, and ensures the consistency and reliability of the UPS;
3.Strong environmental adaptability
Wide voltage input range, avoid frequent battery switching, adapt to areas with harsh power environment;
4.High battery optimization performance
Intelligent battery management function (ABM) technology, prolong the service life of the battery and reduce the number of battery maintenance;
5.Comprehensive and reliable protection
With power-on self-diagnosis function, it can discover hidden dangers of UPS in time and avoid any negligence;
6.Humanized network management
The LCD display panel provides users with accurate information about the working environment and working conditions of the UPS.
