Applications
Data centers & colocation
Parallel modular frames up to 2.0 MVA with N+X redundancy. Hot-swappable modules mean capacity scales with the rack build-out and a faulted module is replaced without dropping the load.
Hospitals & healthcare
Life-safety backup for ICU, imaging and operating theaters. Online double conversion and <1% THDu protect sensitive medical loads; SNMP telemetry feeds the facility BMS.
Semiconductor & cleanroom
Zero-millisecond transition and precise output regulation keep process lines and lithography tools within tolerance through grid events.
Finance & government
Continuous heavy loads with input PF > 0.99 reducing generator and utility strain; LBS option coordinates multiple UPS on a shared bus.
Pair With a Matched Battery Cabinet
XGW modular UPS ships with a matched LiFePO4 battery cabinet on the same DC bus — 384V, 480V or 512V — with an active balancing BMS. See the UPS Lithium Battery Cabinets page, or start from the Critical Power hub.
Frequently Asked Questions
What is the difference between modular UPS and traditional monolithic UPS in critical infrastructure?
A monolithic UPS is a fixed-capacity box; a failure or capacity increase means swapping a whole unit. A modular UPS builds capacity from hot-swappable power modules inside one frame. For critical infrastructure the difference is redundancy and scaling: N+X modular lets a module fail or be serviced without dropping the load, and you add modules as the data center grows instead of installing a bigger box. XGW modular frames parallel into systems up to 2.0 MVA.
Which modular platform covers my site voltage?
XGW modular three-phase UPS spans 380V (50-600 kVA), 480V (60-720 kVA) and 208V (18-360 kVA) platforms, all online double-conversion with input PF > 0.99 and THDi < 3%. Pick the platform matching your utility and load voltage; the battery cabinet is then matched to the same DC bus.
How is redundancy and monitoring handled?
Modules run in N+X with automatic isolation on fault. A 7-10 inch touch LCD with IoT functions plus SNMP, AS400, parallel-kit, SPD and LBS options integrate the UPS with DCIM and building management.
