M90C-2S TAA Compliant Modular UPS – Compact 6U Three-Phase Power Protection

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.

5kW – 8kW | 208/120 VAC | Modular Three-Phase UPS | TAA Compliant for Federal & Enterprise Applications

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 (one power module and one battery module) in just 6U of rack or tower space, the M90C-2S delivers scalable runtime, unity power factor output, and up to 98 percent efficiency in one of the smallest footprints in its class.

The M90C-2S is frequently evaluated as a modern alternative to traditional three-phase UPS platforms from Eaton and Vertiv in space-constrained and regulated deployments.

TAA Compliance Advantage

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.
