Features

20kVA/kW 3-Phase UPS System and Input Isolation Transformer Combined into One Kit
This SmartOnline® kit for 208V IT loads combines Tripp Lite’s S3M20K3B 208/220/120/127V Double-Conversion UPS system and S3MT-20K480V Input Isolation Transformer into one convenient package. The input transformer connects to the UPS system’s input to provide 3-phase voltage step-down and isolation from 480V (Delta) to 208V (Wye). That clean, reliable 208V backup power passes through the UPS system to support your critical loads. The S3M20K-20K4T combo kit is ideally suited for vital applications in banking, education, healthcare, government and manufacturing sectors.

Battery Backup and VFI Operation Protect Critical Loads
The IGBT UPS supports the continuous availability of your most important operational and IT equipment loads through all power conditions, providing a compact backup power platform that’s easy to manage and inexpensive to operate. Sophisticated voltage- and frequency-independent (VFI) operation and advanced IGBT rectifier technology with DSP control deliver reliable output power quality.

Complete Step-Down and Isolation Protection That Prevents Power Disruption
The input transformer offers line isolation and protection to the UPS system and its load. It isolates the UPS and connected components from line surges and spikes caused by utility power disruptions that can damage equipment or corrupt data.

Best-in-Class Footprint for Easy Integration into Your Network Application
The compact design lets you install the steel housings in spaces that would otherwise have required expensive retrofitting. By achieving their condensed size without compromising runtime, reliability or functionality, this combination UPS/transformer kit is recommended for data centers, colocation facilities and edge computing environments that require high efficiency, high performance and clean, reliable power protection, while preserving as much space as possible for revenue-generating server racks.

Efficient UPS Operation and Design Reduces Cost of Ownership
The UPS features ENERGY STAR 2.0-certified technology that provides high operational efficiency to save on utility and cooling costs, as well as protect the environment. It achieves 94% efficiency in double-conversion mode and up to 98% in ECO mode, reducing your power and cooling costs. Unity output power factor (1.0) lets you support more equipment. A low THDi (<2%) improves generator compatibility. A low THDv (≤1%) and active power factor correction with DSP control improve output performance.

Transformer Performs with High Efficiency up to 96.5%
Not only does the input transformer offer up to 96.5 percent efficiency, it also is very quiet with a noise profile less than 65 dBA. A built-in circuit breaker on the output side helps prevent dangerous power overloads. Two ball-bearing cooling fans help prevent overheating. An overheat-sensing relay and switch combine with a red LED indicator to provide over-temperature warning and overheating protection.

UPS Supplies Reliable Battery Backup with Expandable Runtime Options
Three internal battery strings provide 16 minutes of support at half load and seven minutes at full load with zero transfer time. Adding external battery cabinets, such as BP240V09K and BP240V09 (sold separately), provides extended runtime and supports critical loads uninterrupted during successive utility network outages.

Remote Network Monitoring and Control Available 24 Hours a Day
The optional Java-free WEBCARDLXMINI network management card (sold separately) enables remote UPS management through embedded HTML5 web, SSH/telnet and SNMP interfaces, as well as integration with a wide range of network management systems and DCIM platforms. WEBCARDLXMINI also supports EnviroSense2 modules (sold separately), which monitor temperature, humidity and other environmental factors.
