Advance IGBT inverted technology     Combined advanced IGBT technology with hi-frequency wider-modulated technology (PWM), the technology can reduce systematic noise and power loss, so that customer can obtain hi-quality power output and optimized efficiency under each operation load. Advanced control design structure   Advance module design can reduce mean troubleshooting time (MTTR) and keep up best service. and best suitability for 100% 3-phase unbalanced load and non-linear load, must not use the UPS rated capacity under reduced capacity, you can consistently operate under 3-phased 100% unbalanced load. Intelligent by-pass switch   UPS can automatically monitor public power voltage under by-pass circuit mode, if input voltage exceeds rated value -20%～+50%, it shall automatically terminate its voltage output so as to protect from loaded equipment and UPS itself. Personal display interface   Intelligent power management personal display panel is made of mini LCD system, clearly provides with integral operation status while UPS operation, herein LCD shall display public power, battery, output, load and interior status information, thus greatly convenient for operator and user. With remote monitor of RS232 interface and self-test function and timing switching function in this system, the system can realize in monitoring and alarming of each operation status, all information above make it into real intelligent UPS. Advance phase-balanced technology   With most advanced phase-balanced technology now, it features best stability, even if loss-phase, it still operate at normal condition, especially in some worse power supply environment. Sole parallel redundant structure   Only fully understandable for the key load of power supply, you can design satisfactory UPS system, the system adopts most advance technology, featured as unique idea and promoted for multiple UPS parallel structure (RPA) so that system optimizes best reliability. This series adopts parallel system to assure each key part of UPS fully controlled, therefore, the parallel redundancy is the best in the property.
