Q3: What is ECO economic mode?
A: ECO economic mode is when the mains quality is good, the UPS automatically switches to bypass power supply, powered directly by the mains, with efficiency up to 98%, significantly reducing operating costs. When the mains is abnormal, it automatically switches back to inverter power supply to ensure load safety.
Q4: What is 12 pulse rectifier? What are the benefits?
A: 12 pulse rectifier is an input rectification technology that uses a phase-shifting transformer and two sets of 6 pulse rectifiers to reduce input current harmonics from about 30% to about 10%, improve input power factor, reduce harmonic pollution to the grid, and meet stricter grid quality requirements.
Q5: What is the overload capacity of this UPS?
A: 125% overload for 10 minutes then transfer to bypass, 150% overload for 1 minute then transfer to bypass, >150% overload for 200ms then transfer to bypass, with strong overload capacity.
Q6: Can this UPS be configured with external battery packs?
A: Yes. This UPS standard configuration is external battery packs, which can be configured with different capacity batteries according to customer requirements to achieve different backup times.
Q7: What customization options are available for the Three Phase Industrial Frequency On-line UPS?
