GT Series

Globally deployable power protection

GT Series Overview

The global Uninterruptible Power System or GT Series, features Clary’s on-line double conversion technology, and is power factor corrected for a wide range of voltage inputs, (120 VAC through 240 VAC and 50/60 Hz). Computer terminals, workstations and communication equipment are typical electronic products that will benefit from Clary’s GT Series protection. All GT Series systems support a variety of interfaces including Ethernet, SNMP, embedded web server and RS232. Available in tower only configurations, many custom configurations are available. Please call Clary to get a specific solution for your application.
