ONLINE UPS LEVELUPS SERIES 10 – 1000 kVA – CÔNG TY TNHH KỸ THUẬT TOÀN VIỆT
Less energy consumption to supply the loads thanks to high efficiency up to 96%.
Reduced energy loss.
Reduced electricity usage and air conditioning requirements.
Reduction in operating cost of UPS.
IGBT based power factor correction technology provides input power factor close to 1 (≥ 0,99). The high input power leads to reduced electricity pay-out, minimizes cable, switchboard, fuse and generator requirements, thus reducing investment cost.
Low input current total harmonic distortion (THDi) less than 3% helps to avoid the disturbance and expensive harmonic filters.
Small footprint and easy maintenance.
High Output Power Factor 1
Output power factor of 1 (kVA=kW) rate provides up to 25% more active power than a traditional UPS.
Suitable for modern power supply application with unit or capacitive power factor (e.g. new servers generation).
No reduction in active power from 0,9 leading to 0,9 lagging.
Maximum Availability
Parallel configuration up to 8 units per redundancy (N+1) and power increase.
Loop connection helps the UPS system to continue the operation when the connection cable is inturrupted.
