Key Performance BenefitsInput THDi Below 3% — Active front-end filtering keeps upstream harmonic current low, protecting generators and upstream transformers from overheating.Output THDv of 1% on Linear Loads — A clean voltage waveform at the output bus prevents nuisance tripping of sensitive medical and process equipment.97.1% Double Conversion Efficiency — High-efficiency operation holds down energy cost and heat rejection even while delivering premium waveform quality.Unitary Power Factor (PF=1.0) — Every rated kVA is available as real kW, matching the demand of modern imaging systems and motor drives.Medical and Industrial Load Qualification — The EXM2 is optimized for IT, medical, and industrial applications where load character varies between resistive, inductive and non-linear.MTTR Below 5 Minutes — Serviceable architecture with SCR bypass and modular IGBT stages returns the unit to service quickly after a fault event.SNMP, Modbus and Dry Contacts — Standard interfaces feed power quality and battery data into hospital BMS and industrial SCADA platforms.Technical SpecificationsTechnical IndicatorSpecification Detail (EXM2)Power Rating100kVA to 250kVA (100 / 120 / 160 / 200 / 250kVA)TopologyOnline Double Conversion (VFI) with Dynamic Online ModeConversion EfficiencyUp to 97.1% (Double Conversion) / 99% (Dynamic Online) / 99.2% (ECO)Input Current THDiBelow 3%Output Voltage THDvLess than or equal to 1% (linear) / 3% (non-linear)Battery CompatibilityVRLA and Lithium-ion (HPL UPS BMS)Dimensions (W*D*H)600 x 850 x 1600 mm (100-200kVA) / 600 x 850 x 2000 mm (250kVA)EXM2: Why Power Quality Decides Equipment AvailabilityHospital imaging suites and industrial control rooms share a hidden vulnerability: the power feeding them is never purely sinusoidal, and the equipment inside them is increasingly sensitive to distortion.MRI scanners, CT systems and precision lab instruments can misbehave or abort scans when supply voltage harmonics exceed equipment tolerance.On the input side, non-linear loads pull harmonic current upstream, overheating distribution transformers and forcing diesel generators to derate.The Vertiv Liebert EXM2 attacks both directions of the problem with active input filtering that holds THDi below 3% and output regulation that keeps THDv near 1% on linear loads.At 97.1% double-conversion efficiency, the waveform improvement is not bought with excessive energy loss, a trade-off many legacy online UPS units could not avoid.The 600mm wide frame fits standard electrical rooms, while the MTTR below 5 minutes limits downtime exposure when a fault does occur.SNMP, Modbus and dry-contact interfaces stream the same power quality data into BMS and SCADA systems that already monitor the rest of the facility.For facilities standardizing one UPS platform across IT, medical and production zones, the EXM2 provides a single specification that satisfies all three load classes.Deploying the Liebert EXM2 in the 100kVA to 250kVA range gives medical and industrial facilities a power quality anchor rather than a simple backup device. Low input harmonics protect upstream assets and keep generators available at full rating during outages, while clean output voltage keeps sensitive loads running without nuisance alarms. Efficiency above 97% limits the operational cost of that protection, and the compact footprint fits retrofit projects where electrical room space is fixed. With lithium-ion compatibility available through the HPL UPS BMS, facilities can also reclaim floor area and extend runtime in the same footprint. For engineers accountable for uptime in regulated environments, the EXM2 translates waveform specifications into measurable equipment availability.Technical FAQQ: Does the EXM2 require an input isolation transformer for medical installations?A: The double-conversion topology provides galvanic separation in the DC link; site-specific isolation requirements depend on the medical equipment standard and should be confirmed with the project specification.Q: How does Dynamic Online mode affect output waveform quality?A: Dynamic Online maintains inverter supervision with near-zero transfer time, preserving clean output while operating at 99% efficiency; it is not a passive bypass mode.
