Overview
The SUT20K SmartOnline® SUT Series 3-Phase 208/120V 220/127V 20kVA 20kW On-Line Double-Conversion UPS provides complete protection against power interruptions and fluctuations that can contribute to equipment failures and data loss. It’s recommended for critical data center, telecommunications, computer network, manufacturing and financial applications.
The Voltage and Frequency Independent (VFI) design allows continuous operation at either 50 or 60 Hz. Zero transfer time from online to battery mode ensures no disruption to attached equipment loads. Offering an efficiency of 94% during normal operation and 98% in economy mode, the SUT20K reduces energy losses for cost-saving operation. Automatic bypass keeps connected equipment powered, even during overloads and many potential UPS fault conditions.
IGBT inverter technology produces output power with less than 2% total harmonic distortion (THDi) 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 SUT20K 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 AC, bypass, battery and fault modes. A built-in card slot supports optional remote management cards, such as WEBCARDLX, for comprehensive monitoring and control over a network.
