208V Modular Online UPS Comparison for Mission-Critical Applications
Modular online double-conversion UPS systems are widely deployed in data centers, edge facilities, and industrial environments where uptime and scalability are essential.
The Xtreme Power M90U-80 supports up to 80 kW capacity within a single cabinet and includes integrated internal battery options and standard maintenance bypass. The Vertiv Liebert APM2 208V supports modular configurations up to 60 kW in internal battery configurations, with additional scalability depending on frame size.
For applications requiring higher usable capacity and longer internal runtime at load, the M90U-80 delivers stronger scalability and service integration.
