    Upon generation, ac power is clean and stable. However, during transmission and distribution it is subject to voltage sags, spikes and complete failure that may interrupt computer operations, cause data loss and damage equipment. The S4K2U-5C protects equipment from these disturbances. The S4K2U-5C continuously charges its batteries from mains power, enabling it to supply power to connected loads even when mains power fails.
