An entry point into modular UPS

The M90S-2S is designed for facilities where power requirements exceed rack-level UPS capability but remain within single-phase infrastructure. Built on a 2-slot architecture using a 6 kW power module, it delivers 6 kW of centralized capacity with module-level serviceability and flexible runtime configuration in a compact platform — a practical entry point into centralized modular UPS without the complexity of larger systems. Individual power and battery modules can be serviced or replaced without removing the entire system, reducing downtime in compact electrical environments.

What the M90S-2S delivers

The entry modular tier

The M90S-2S is the entry platform of the M90S family — a fixed 6 kW centralized system for single-phase infrastructure, typically deployed in electrical rooms supporting localized infrastructure, where several small UPS would otherwise be used, or in facilities moving from distributed to centralized UPS design. For capacity scaling and N+1 redundancy, the scalable platforms step up from here.

Choose the M90S-2S for a fixed 6 kW centralized system with module-level serviceability and simple deployment; step up to the M90S-4S (6–12 kW), M90S-6S (6–24 kW), or M90S-12S (6–48 kW) when capacity scaling or N+1 redundancy is required.

Consolidating distributed UPS

As infrastructure grows, managing multiple small distributed UPS adds complexity. The M90S-2S consolidates that protection into a single 6 kW system — enabling unified runtime planning, simplified maintenance, reduced system fragmentation, and consistent deployment across sites. It is well suited to environments moving toward a structured, centralized power architecture while remaining on single-phase infrastructure.

Flexible electrical integration

The M90S-2S supports simplified deployment using a factory-installed L14-30P input line cord — enabling installation without hardwired infrastructure — or a hardwired connection. Output distribution is delivered through terminal blocks and/or a configurable receptacle panel, so the UPS matches the connector mix a deployment needs. It mounts in a standard rack with a 4-post rail kit (6U) or installs as a tower on a caster base, making it suitable for telecom rooms, electrical closets, commercial environments, and residential systems.

Available output distribution: IEC C19, NEMA 5-15R / 5-20R, NEMA L6-20R / L6-30R, and NEMA L14-30R. Options include the L14-30P line cord, receptacle panel, extended battery cabinet, caster base, 4-post rail kit, and a 5-year extended warranty.

Runtime by load and battery module count

Runtime in minutes at 50% load (3 kW) and 100% load (6 kW) by number of installed battery modules. In the 6 kW configuration the enclosure holds one internal battery module; modules 2–8 are added with the optional BC7 battery cabinet.

Estimated minutes; values vary with battery age and site conditions. A maximum of eight battery modules is supported per power module. For longer runtimes or extended-battery configurations, contact Xtreme Power engineering at (800) 582-4524 or sales@xpcc.com.

Where the M90S-2S is deployed

The M90S-2S is deployed in environments requiring centralized single-phase power protection — telecommunications infrastructure, network distribution rooms (IDF/MDF), broadcast and media systems, commercial infrastructure nodes, industrial automation, and residential technology environments — typically where load exceeds rack-UPS capability, several distributed UPS need consolidating, centralized runtime planning is preferred, or simple deployment without electrical upgrades is required.
