The DT Series ET is a digital Uninterruptible Power System (UPS) which features Clary’s on-line double conversion, power factor corrected technology built for extreme temperature. Not only does the DT Series ET offer the highest reliability available on the market today, we consider it on-line double conversion technology at its best.

We’ve built this system for that application where all others have failed due to extreme indoor or outdoor environmental conditions. Operating in temperatures from -40°C to +74°C, the UL listed DT Series ET is ideal for those areas not environmentally controlled and in remote locations.

All DT Series ET systems utilize power factor corrected, and RS232 and SNMP protocols are supported. Available in rack-mount configurations with extended battery run times, custom configurations and engineering available.

Clary’s DT 1000R ET is the world’s most advanced Uninterruptible Power System (UPS) for extreme environment applications. The DT 1000R ET keeps equipment running for 10 minutes to 10 hours or more (dependent on optional battery sizing) during power failures. Clary’s special Outpost™ batteries fit inside many existing cabinets and meet all NEMA temperature specifications for outdoor use.
