Features
Protects Mission-Critical Rack-Mounted Equipment against Damage, Downtime and Data Loss
This N+1 UPS system protects connected equipment against damage, downtime and data loss due to power outages, voltage fluctuations and transient surges. Featuring an 18,000W capacity, high 0.9 power factor, true on-line operation with pure sine wave output and zero transfer time to battery, the SmartOnline® SU20KRT-1TFTAA provides the highest level of battery backup and AC power protection for critical server, network and telecom equipment. It offers automatic N+1 redundancy at load levels up to 10kVA and non-redundant operation from 10kVA all the way up to 20kVA. Using the step-down transformer, the 20kVA UPS system can support both low- and high-voltage equipment.
Reliable, Expandable Battery Backup
UPS battery backup keeps connected equipment operational through short power failures, and provides time to save data and perform an orderly system shutdown in case of a prolonged blackout. The external battery provides 12.5 minutes of support at half load and 4.3 minutes at full load. During normal operation, incoming utility power keeps the battery fully charged so backup power will be available when needed. For mission-critical applications demanding continuous uptime, the 20kVA UPS can provide expandable runtime with optional external battery packs, such as Tripp Lite’s field-replaceable, hot-swappable BP240V10RT3UTAA (sold separately). A battery-independent restart ensures automatic UPS power-up after lengthy power outages, even with expired batteries.
Easily Hot-Swappable with No Expensive Service Calls or Downtime Needed
With its parallel PDU, the SU20KRT-1TFTAA with manual bypass switching enables hot-swappable replacement of all major UPS system components in both N+1 and combined operating modes. In bypass mode, the PDU passes power to equipment without the use of the power and battery modules, allowing them to be removed while keeping your application in operation. When making repairs or replacing a battery, no lengthy service calls or downtime are necessary.
Intuitive Front-Panel Interface for Convenient UPS Operation and Monitoring
Front-panel LEDs indicate line power, online mode, bypass mode, on-battery, charger and AC output status at a glance. The LCD readout with scroll controls supports visual monitoring of a variety of control options to support advanced UPS settings and configurations. The panel rotates for comfortable viewing in rack-mount or tower configuration.
Optional WEBCARDLX Network Interface Offers 24/7 Access
An accessory slot accommodates the optional Java-free HTML5-based WEBCARDLX interface, which enables full remote access for site power and UPS status monitoring, configuration, control and email notifications via secure web browser, SNMP, telnet or SSH. It supports 10/100 Mbps auto-sensing for optimum communication with an Ethernet network. Automated alerts help prevent accidental overloads, power loss and downtime.
Advanced Communications Ports
USB and DB9 ports (cables are included) enable data-saving unattended shutdown of connected systems when used with Tripp Lite’s free downloadable PowerAlert® software. Capabilities include detailed monitoring of load levels, self-test data and utility power conditions.
Versatile Installation Options
Hardware is included for mounting the 20kVA UPS system in 14U of space in an EIA-standard 19-inch 4-post rack. Use six optional 2POSTRMKITHD kits for 2-post rack mounting or two optional 2-9USTAND kits for mounting in an upright tower position.
TAA-Compliant UPS for GSA Schedule Purchases
The SU20KRT-1TFTAA is compliant with the Federal Trade Agreements Act (TAA) for GSA Schedule purchases.
2-Year Warranty, $250K Ultimate Lifetime Insurance and Environmentally Responsible Design
The SU20KRT-1TFTAA comes with a 2-year warranty and $250,000 of Ultimate Lifetime Insurance for any connected components damaged by a power surge (U.S., Canada and Puerto Rico only). It’s manufactured in compliance with strict RoHS specifications, reflecting Tripp Lite’s commitment to environmental responsibility.
