Description
High-Efficiency, Space-Saving 3-Phase UPS for Critical Applications
The Eaton Tripp Lite SmartOnline S3M20K-NIB delivers 20kVA/kW of reliable, clean double-conversion power for mission-critical environments including banking, healthcare, education, government, and manufacturing. This compact UPS system supports continuous uptime and superior output quality through advanced IGBT rectifier and DSP control, all in the industry’s smallest 3-phase 208V footprint.
Battery Flexibility and Scalable Runtime
The S3M20K-NIB operates with external battery cabinets (sold separately), enabling flexible and expandable backup options tailored to your power needs. No internal batteries are included, allowing you to pair with compatible cabinets like BP240V09K, BP240V40/40L, BP240V65/65L, or BP240V100/100L.
Powerful Features and Intelligent Monitoring
With ENERGY STAR® 2.0 certification and up to 98% efficiency in ECO mode, the S3M20K-NIB significantly lowers energy and cooling costs. The five-inch color touchscreen provides real-time monitoring, while optional network cards and MODBUS ports offer remote management capability. Parallel configuration is supported for capacity expansion or redundancy.
Ideal for data centers, edge computing, and space-constrained environments.
