Uninterruptible power supply (UPS) is the core component of a power system and is widely used in data centers, industrial control centers, servers and special industrial equipment. When the AC power supply is normal, UPS can eliminate the surge in the AC power and stabilize the filter. When the AC power supply is abnormal, the UPS can immediately transform into a power supply device to offer power to the load equipment.
With the AI technology application in various industries, the digitization and intelligence of data center site facilities and infrastructure is gradually becoming a trend, the demand of UPS is becoming more and more prosperous. In 2025, the global UPS power supply market is expected to reach 64,958 million RMB.
Currently the top 10 UPS manufacturers in the world are SANTAK, HUAWEI, APC, Virtue Energy, KELONG, VERTIV, EATON, KSTAR, DELTA, EAST. Among them, Virtue Energy’s UPS are widely used in government, banking and internet industries.
