1 kVA Backup Uninterruptible Power Supply, 120V/220V

Features

1. Wide range of voltage/frequency input.

• 1kVA UPS for computer has automatic on-line voltage stabilization and input voltage ranges from 81V to 145V AC or 162V to 290V AC, which effectively reduces the battery usage rate, thereby extending the battery life, especially suitable for areas where there are large power grid fluctuations and poor power environment. 120V UPS power supply, 240V backup power supply are available.

2. Excellent microprocessor ensures reliable operation.

• The domestic UPS power supply adopts advanced microcomputer (CPU) control technology, faster and more accurate data processing and control.
• With interactive design, the UPS system uses AC to DC to charge the battery and ensures that the built-in battery has enough energy during running.
• Advanced Hall devices and high quality components are adopted in UPS power supply for laptop to provide users with a reliable power supply. Best backup power supply for PC.

3. Intelligent no-load automatic on and off technology.

• When the utility power is supplied, the backup power unit will automatically turn on and the battery will be charged at the same time.
• The system will automatically detect the load when the UPS is in the shutdown state and power failure. If the load is less than 5%, the UPS will be in no-load state and automatically shut down after 1 minute to reduce loss and effectively extend the battery lifespan.

Specification

If the UPS is overloaded and exceeds a certain range, the UPS will automatically shut down. If it is in the inverter state, it will often cause the breakdown of the inverter transistor and the UPS will be damaged. Generally speaking, the maximum load of a UPS power supply should be 80% of its nominal load. For example, if you buy a 1000W UPS, 800W (1000W*80%) is used to match the load. We recommend that the load rate accounts for 30~80% of the UPS power. If the load is too large, the UPS power supply may be overloaded when they are started at the same time. On the contrary, if the load is too small, it not only causes waste, but also is bad for the battery performance. UPS emergency power supply is very useful at home and infactory. Buy uninterruptible power supply here now.
