A UPS with a high input power factor allows for effective power grid utilization and reduced power grid interference. The input power factor of the UPS2000-A series (1 kVA to 3 kVA) is ().
Which of the following communication methods doesthe UPS2000-G series (6 kVA to 20 kVA)support?
(Multiple Choice)
Which of the following items is required if the UPS5000-E adopts both dry contact card and backfeed protection card?
For the UPS2000-G series (6 kVA to 20 kVA), the main input voltage ranges from 80 V to 280 V, and the input frequency ranges from 40 Hz to 70 Hz. A wide input range effectively reduces the battery switch times, failure probability, and battery charge/discharge times, helping improve the battery life.
The UPS5000-E has strong load adaptability. It does not derate in case of leading/lagging capacitive/inductive loads.
If the UPS5000-E (50 kVA power module) backs up power without derating, it is unreasonable to configure () 12 V batteries.
The output THDv of the UPS5000-E (50 kVA power module) is (). (Multiple Choice)
For traditional UPSs, the number of batteries cannot be adjusted/ and the battery maintenance cost is high because one faulty battery can result in replacement of the whole battery string. For the UPS5000-A, the number of batteries can be adjusted between ().
With high-efficiency rating, the UPS2000-G series was the first in the industry to earn Energy Star certification from the U.S.
The number of battery strings for the UPS5000-A can be adjusted. To avoid replacing the whole battery string due to one faulty battery and solve the battery maintenance difficulty of traditional UPSs.
