5kVA / 8kVA
208/120 VAC Three-Phase
High-efficiency modular UPS with maintenance bypass, optional receptacle panels, and TAA compliance for continuous power in IT and industrial environments.
The Xtreme Power M90C-2S is a TAA compliant modular UPS designed for federal agencies, defense facilities, small data centers, and enterprise IT environments where secure, high-efficiency, three-phase power is essential. Featuring a dual-slot chassis (1 power module + 1 battery module) in just 6U of rack or tower space, the M90C-2S delivers scalable runtime, unity power factor output, and up to 98% efficiency in the smallest footprint in its class.
This compact UPS solution meets Trade Agreements Act (TAA) requirements, making it fully approved for U.S. Government and public-sector procurement.
Unlike many competing modular UPS products, the M90C-2S is fully TAA compliant, ensuring eligibility for GSA contracts, Department of Defense deployments, VA facilities, federal data centers, and government-funded infrastructure projects. It delivers secure, trusted power protection while meeting procurement standards without waiver requirements.
