[335999 ] = All other miscellaneous electrical equipment and component manufacturing — Uninterruptible power supplies (UPS) manufacturing
An uninterruptible power supply (UPS) is an essential part of every home network system. Since the network is attached to peripheral devices all over the home, it is possible that selected units will each have their own UPS. Since power outages are becoming more common, whole house automatic generators are also becoming more common. In the presence of such a system, each UPS needs only provide enough operational time until the transfer circuitry reapplies power to the home.
Without an automatic generator, each UPS must operate until alternate power (storage batteries or portable generator) are attached to the system. In the future, specialized UPSs may provide computer circuit voltage directly to the computer without needing to be inverted and stepped down again through a computer power supply. Such UPSs would be much more efficient, allowing networks to stay operational much longer.
