Key Performance BenefitsN+1 Redundancy in a Single Frame — One spare 18kVA module covers the frame, so the loss of any single module does not interrupt the protected load.Online Module Replacement — Power modules are exchanged while the UPS remains in double conversion, avoiding a transfer to bypass during service work.18kVA Redundancy Granularity — Redundancy is added in 18kVA steps, so the spare capacity is sized to the frame rather than purchased as an entire second system.96.5% Double Conversion Efficiency — Redundant operation does not require accepting avoidable conversion loss, keeping heat and energy cost controlled.Unitary Power Factor (PF=1.0) — Each module delivers its full rating in kW, so fewer modules cover the same real load with redundancy in place.Load Sharing Across Modules — Modules share the load automatically, so a remaining unit carries the full IT demand without manual intervention after a fault.Intelligent Battery Monitoring — Testing and deep discharge protection support the same availability objective on the DC side as on the AC side.Technical SpecificationsTechnical IndicatorSpecification Detail (APM90)Power Rating18kVA to 90kVA (Scalable in 18kVA modules)TopologyModular Online Double ConversionRedundancy OptionsN, N+1 or N+X within a single frameModule Size18kVA/18kW High-Density Power ModulesConversion EfficiencyUp to 96.5% (Double Conversion) / Up to 99% (ECO Mode)Frame CapacityUp to 90kVA/kW per frameService AccessFront-access hot-swap modules with LCD/LED management interfaceAPM90: Redundancy That Does Not Require a Second UPSConventional redundancy planning forces a choice between buying a full second UPS cabinet or accepting a single point of failure in the power path.A parallel system doubles the footprint, cabling and switchgear, while a non-redundant unit leaves the entire load exposed to one rectifier or inverter fault.The reason the decision is difficult is that protection is purchased at full-cabinet cost even when only a fraction of capacity needs to be duplicated.The Vertiv Liebert APM90 resolves that trade-off by providing redundancy at 18kVA module granularity inside one frame, so a single spare module covers the installation.Because modules share load automatically, the remaining units continue to carry the IT demand if one fails, without operator action and without a transfer to static bypass.Service work follows the same logic: a module is extracted and replaced while the UPS stays in double conversion, keeping the load on conditioned power throughout the maintenance window.At 96.5% double-conversion efficiency, running with a spare module does not require tolerating avoidable losses, and the unitary power factor means each module contributes its full rating in kW.Battery testing and deep discharge protection apply the same availability discipline to the DC side, where many outages originate.Specifying the Liebert APM90 with N+1 modular redundancy gives IT rooms the availability profile of a parallel system without the cost and space of a second cabinet. Module-level spares replace cabinet-level duplication, and online replacement avoids the load transfers that turn routine maintenance into a risk event. Efficiency above 96.5% keeps the redundant configuration economically defensible, while unitary power factor reduces the module count needed to cover the same load. For facility teams accountable for continuous operation in space-constrained rooms, the APM90 delivers redundancy as an incremental design choice rather than a structural one.Technical FAQQ: How is load handled if two modules fail simultaneously?A: Remaining modules continue to supply the load up to their combined rating; whether the load is fully supported depends on configuration and actual demand at the time of the fault.Q: Does module replacement require an external bypass cabinet?A: Modules are hot-swappable within the frame; the need for external bypass depends on site procedures and the maintenance policy applied to the installation.
