Mr. Nam Paik, Director of Engineering at TSi Power, says, "The UPs-400Wtb is the ideal UPS for computer or telecommunications equipment in extreme wide temperature environments where ac power delivery is unreliable and/or long battery backup times may be necessary. Its operating temperature range is –20°C (–4°F) and as high as 60°C (140°F). It protects connected equipment from power supply failure, erroring, system lock-ups and re-boots."

Custom outdoor enclosures for OEM applications are also available.

The capability of adding extra external battery packs enables nearly unlimited holdup times

The UPs-400Wtb comes with a built-in Anderson SB-50 Connector. This enables connection of a virtually unlimited number of extra EXt-400 battery packs, as each one contains its own separate charger.
