Tripp Lite's SU20K3/3 20kVA SmartOnline 3-Phase Intelligent, True On-Line UPS System has been redesigned
to save valuable space and simplify runtime scalability. Power and battery components are combined into a
single, small-footprint module (the smallest in its class). A robust internal battery runtime capability can be easily
extended by installing additional optional internal battery packs through the convenient front panel access door.
The SU20K3/3 provides mission-critical equipment with the highest level of power protection available. Large
capacity 20,000VA/16,000 watt UPS continually converts incoming AC power into filtered DC power, and then
resynthesizes it back into AC power with a pure sine wave. Perfectly regulated, continuous sine wave output with
zero transfer time offers compatibility with all equipment types. IGBT inverter technology produces output power
with <3% THD (total harmonic distortion), allowing connected equipment to perform at its peak. A 3:1 crest factor
safely supports a variety of equipment, even those with wildly-fluctuating power demands. Extremely efficient
double-conversion operation
3 communication ports, SNMP
card slot and EPO jack

operation saves money by lowering electricity consumption. Hardwire input and output connections support a variety of permanent or PDU style power
connections. SU20K3/3 features 120/208V AC, 3-phase, 4-wire (plus ground), wye input and output. It also features a wide input voltage correction range:
96-144/166-250V AC. Frequency is 50 or 60 Hz (auto-selectable). SU20K3/3 includes internal power and battery components in a single small-footprint tower
module. Battery support can be extended with additional internal battery packs. A manual bypass switch as well as an automatic bypass function ensure 100%
availability of connected equipment by safely passing through AC power when the UPS requires maintenance. Three built-in communication ports (RS-232,
contact closure and AS-400) work with included PowerAlert Software to simultaneously provide shutdown commands and reporting on multiple servers without
the need for costly accessories. An accessory slot accepts an optional internal SNMP card (model # SNMPWEBCARD) for remote shutdowns, reboots and
more. A Battery Start Switch allows cold restart of UPS during a prolonged blackout to utilize its batteries for periodic system access or data retrieval. An
Emergency Power Off button turns UPS output OFF and disables Bypass output. Built-in Emergency Power Off (EPO) interface supports remote emergency
shutdown in large facilities. Front panel combination LCD/LED display alerts users to a variety of UPS operational modes and conditions. A start-up service
program is recommended to enhance the reliability of the installation.
