Tripp Lite UPS 3-Phase Smart Online 50kVA+Input Isolation Transformer Kit 480V – Tower – 480 V AC Input – TAA Compliant

50kVA 3-Phase UPS System and 60kVA Input Transformer Combined into One Kit

This SmartOnline® kit for 208V IT loads combines Tripp Lite’s S3M50K 208/220/120/127V Double-Conversion UPS system and S3MT-60K480V 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 S3M50K-60K4T 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 (<3%) improves generator compatibility. A low THDv (≤2%) and active power factor correction with DSP control improve output performance.

Transformer Performs with High Efficiency up to 97.5%

Not only does the input transformer offer up to 97.5 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. Four 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.

External Batteries Supply Reliable Backup with Expandable Runtime Options

The S3M50K uses external battery cabinets, including BP240V40L, BP240V65/65L and BP240V100/100L (sold separately), to provide backup support in case of a power failure. These cabinets are available with or without internal batteries. No internal batteries are included with the S3M50K. A one-touch cold-start button powers up the UPS with battery power only.
