Overview
The SUTX20K SmartOnline® SUTX Series 3-Phase 220/380V, 230/400V or 240/415V 20kVA 20kW On-Line Double-Conversion UPS provides battery backup and AC power protection against power disturbances that can damage electronics or destroy data. It’s recommended for critical data center, LAN/WAN and distributed server room applications.

The SUTX20K’s Voltage and Frequency Independent (VFI) design allows continuous operation at any supported voltage at either 50 or 60 Hz. Zero transfer time to battery mode ensures no disruption to the attached loads. Automatic and Manual Bypass keeps connected equipment powered, even during overloads and UPS maintenance.

IGBT inverter technology produces output power with 1% total harmonic distortion (THD) to keep connected equipment functioning at its peak. A 3:1 crest factor safely supports a variety of loads, even those with wildly fluctuating power demands.

Managing the SUTX20K is simplified through the multi-language LCD interface, which displays critical operating conditions and diagnostic data, such as battery and load status. Four LEDs indicate bypass, line, battery and fault modes. A serial port allows connection to Tripp Lite’s free local shutdown agent. A built-in card slot supports the optional WEBCARDLX network management card for network interface and remote monitoring and control.
