2.2 Abstract of Product
2.2.1 Product Feature
KR series (6&10kVA) UPS are online UPS of sine wave charactering high-performance, especially designed
for network computer room, small intelligent equipments like measure devices or industrial auto-machines
etc. and precise instruments used in systems such as finance, communication, insurance, transportation,
taxation, military, stock, energy, education, government and enterprises etc, specially for terrible electric
network circumstance.
KR series (6&10KVA) UPS, the online UPS of sine wave charactering high-performance has mainly the
following features:
Great adaptability for AC input
Within wide input voltage range, there is no need for battery supply which can effectively protect batteries.
Precise synchronization system with AC input
The realization of exact zero-phase synchronization between output and input can meet the requirement to
synchronization of power supply and electric network from a variety of instruments, being propitious to
improve user system performance and boosting the reliability of bypass switch.
High input power factor
Adopt advanced active PFC technique, single phase input power factor could reach 0.99, 3 phase input power
factor could reach 0.95, which further alleviates load on electric network and represents green power supply
of new generation.
High performance with competitive price
Adopt multiple power transfer and high frequency PWM technique, character high efficiency, small size and light
weight, improve running reliability and reduce manufacturing cost. All above help decreasing customer cost
of system designation.
Low running input voltage
