◆ 12 - pulse rectifier as s tandard configuration for UPS over 50 KVA, will increase input power factor from 0.66 ~ 0.83 under 6 - pulse rectifier to over 0.97, significant ly sav ing energy; And reduce i nput current harmonic distortion (THD I) to below 5% (with nonlinear load), therefore not only greatly reduc ing the pollution by UPS its own to Grid system, also eliminat ing the load harmonic pollution to Grid system and correcting power factor; ◆ Concise operation process with freestart-shutdown sequence, avoids the fact caused by human error that UPS waslocked down with no-output and meantime could not auto-switch to the bypass to support power supply to load so that the load have to stop working. Even more, when manual maintenance switch is mis-operated, UPS will immediately switch to the bypass to avoid the damage upon Inverter and ensure the output without any interrupt.
◆ 50KVA以上标配12脉冲整流器，将UPS的输入功率因数，由6脉冲整流的0.66~0.83提高到大于0.97，显著节能；输入端电流谐波分量（THD）降至8%以下，除了可以大大降低UPS自身对电网的污染外，还可以消除所带负载对电网的谐波污染和校正功率因数； ◆ 简洁的无开关机顺序的操作流程，避免了因为人为疏忽错误操作而造成UPS锁机无输出且不转旁路造成负载失电宕机的问题，而且即使误操作手动维修开关时，UPS也会立即转跳转旁路输出而不会损坏UPS逆变器，并确保输出不中断；
