On-Line UPS

On-line UPS is the top line UPS that gives you a wide range of features to help protect your equipment from a power failure to overvolting. One of the features that an On-line UPS offers is that it double converts the current from AC to DC and then from DC back to AC but with the ideal output power. This feature is what isolates connected equipment from blackouts, brownouts, overvoltages, surges, line noise and electrical impulses. A typical On-line UPS regulates its voltage within +-2-3%.

We only have suppliers who meet our supply chain standards for quality (ISO 9001), health and safety (ISO 18001), and environmental management (ISO 14001).
