Tripp Lite’s New 3-Phase UPS Combines High-Performance Power with Best-in-Class Size

UPS Series Brings Market-Leading Power Protection to Small Spaces

Chicago, IL (May 4, 2021)—Tripp Lite, a global manufacturer of power and connectivity products, gives IT professionals an unprecedented UPS solution for 208V 3-Phase power protection in a minimal amount of space. The new S3M SmartOnline® UPS series, ranging from 10 to 100 kVA/kW, provides best-in-class footprint and power density. All units also feature ENERGY STAR® 2.0 certification of highly efficient operation that saves energy, reduces costs and protects the environment. The S3M series is ideal for data centers, colocation facilities and edge computing spaces in corporate, telecom, government, retail, manufacturing, transportation, healthcare, financial and educational environments where the highest uptime and operational efficiency are required.

The 15-model S3M UPS series provides clean and continuous 208V/220V Ph-Ph power with unity power factor design to critical IT equipment loads ≤ 80 kW or 10 racks at 8 kW/rack per 100 kVA/kW UPS unit. S3M UPS models are also conveniently available with 600V input and 480V input and output transformer kits. The UPS systems' large, easy-to-use color touchscreen display, remote network management capabilities, high efficiency and low mean time to repair (MTTR) add convenience and lower the total cost of ownership (TCO).

“The S3M series’ unmatched combination of industry-leading features and compact footprint gives IT managers power protection options they’ve never had before,” said Jose L. Medina, 3-Phase UPS and Cooling Solutions Manager. “They can save space for revenue-generating equipment without compromising the runtime, reliability or functionality you would expect from a 3-phase UPS.”
