About the Vertiv Liebert MPX 250kVA Modular UPS

The Vertiv Liebert MPX 250kVA is a modular, scalable three-phase uninterruptible power supply engineered for hyperscale data centers and carrier-grade facilities. The system architecture leverages distributed power modules that allow capacity expansion in increments, enabling organizations to match UPS deployment to actual load growth while optimizing capital expenditure and infrastructure footprint.

Designed for high-density computing environments, the MPX 250kVA supports dual-conversion online topology with integrated static bypass, delivering continuous conditioning of incoming AC power to sensitive server, storage, and networking equipment. The modular design reduces single points of failure by distributing power processing across multiple independent converter modules, each capable of autonomous operation and load sharing.

Target deployments include mission-critical cloud infrastructure, telecommunications hubs, financial transaction processing centers, and disaster recovery facilities where unplanned downtime carries operational and compliance penalties. The system accommodates both standard and extended runtime configurations through external battery module integration.

Ideal for

  • Hyperscale data center UPS backbone supporting 500+ server racks with modular capacity additions
  • Carrier-grade telecommunications switching station requiring N+1 redundancy and autonomous module failover
  • Financial services trading floor infrastructure with sub-millisecond switchover and zero data loss requirements
  • Cloud service provider colocation facility with multi-tenant isolation and granular power allocation
  • Research computing cluster demanding consistent power conditioning across variable load states
  • Distributed edge computing node protection with standardized modular replacement procedures
