Vertiv MUEXM480-100BAP 100kVA 480V Online UPS

Overview

The Vertiv MUEXM480-100BAP is a Liebert EXM Basic Plus configuration rated at 100kVA on a 480V platform — positioned in the mid-range of the EXM family, which spans 30 to 250kVA at 480V. If you are protecting a medium-to-large server room, a data hall row, or critical industrial equipment running on three-phase 480V distribution, the 100kVA point in this family is a common sizing target that balances headroom against capital cost. The MUEXM480-100BAP (often searched as MUEXM480 100BAP) carries the "1PM" designation indicating a single power module configuration in this chassis.

Key Features

• 480V Three-Phase Input: The 480V bus aligns with standard US commercial and industrial distribution panels, avoiding the step-down transformer losses you incur when feeding a 208V UPS from a 480V service — relevant in facilities where the utility drop is 480V and you want to minimize conversion stages.
• 100kVA Capacity at the 480V Platform: Within the EXM 480V family range of 30–250kVA, 100kVA positions this unit to handle substantial IT or industrial loads. Correctly sizing UPS capacity to 60–80% of nameplate is standard practice — at 100kVA nameplate, that gives you a comfortable operating window before you approach thermal derating territory.
• Liebert EXM Platform: The EXM line is Vertiv's online double-conversion architecture for three-phase applications, meaning load current passes through the inverter continuously rather than relying on transfer switching. This eliminates the brief transfer gap present in line-interactive designs — a meaningful distinction for sensitive equipment intolerant of even millisecond-level voltage excursions.

Integration and Compatibility

The EXM platform is designed for integration with Vertiv's Liebert monitoring and management ecosystem. For installations requiring visibility into power chain health alongside physical security infrastructure, verify SNMP card availability and NMS compatibility with your existing building management or DCIM platform before procurement. Consult Vertiv's current configuration guides for module, battery cabinet, and maintenance bypass options compatible with the MUEXM480-100BAP chassis.

Frequently Asked Questions

Q: What is the power rating of the MUEXM480-100BAP?

A: The MUEXM480-100BAP is rated at 100kVA on the Liebert EXM 480V platform. The EXM 480V family spans 30 to 250kVA, placing this unit in the mid-range of the line.

Q: What does the "1PM" designation mean in this model?

A: The 1PM designation indicates a single power module configuration within the EXM chassis. Multi-module configurations are available at other model designations within the EXM family for redundancy or higher capacity requirements.

Q: Is the MUEXM480-100BAP an online double-conversion UPS?

A: The Liebert EXM platform uses online double-conversion topology, meaning the load runs continuously through the inverter. This eliminates transfer time gaps that occur with line-interactive designs and provides consistent output power quality regardless of input anomalies.

Q: What input voltage does the MUEXM480-100BAP require?

A: This unit operates on a 480V three-phase platform, consistent with standard US commercial and industrial electrical distribution. Verify your facility's service voltage and available amperage before ordering to confirm suitability.

Ted Perry

The MUEXM480-100BAP sits at the 100kVA mark on Vertiv's EXM 480V platform — a family that runs from 30 to 250kVA — which makes it a realistic fit for medium-density data rooms or industrial process equipment where three-phase 480V distribution is already in place and you want online double-conversion protection without oversizing into the upper range of the family.

Technical Highlights:

• 480V Platform Alignment: Running at 480V rather than 208V reduces distribution current at a given kVA load, which can mean smaller wire gauges and lower I²R losses across longer cable runs in larger facilities — a practical efficiency consideration at 100kVA scale.
• 100kVA Nameplate in the EXM 480V Range: The EXM 480V family covers 30–250kVA; 100kVA gives you roughly 30–40kW of usable headroom when loaded to recommended 60–80% of nameplate, which is appropriate for mid-density server rows or critical manufacturing controllers.
• Single Power Module (1PM) Configuration: The 1PM build is the baseline chassis; if your site requires N+1 internal redundancy, verify whether an alternate EXM configuration with multiple power modules is the right selection before committing to this unit.

Deployment Considerations:

• Confirm available fault current and breaker sizing at the 480V service panel before installation — 100kVA at 480V three-phase draws significant input amperage and requires coordinated overcurrent protection upstream.
• Battery cabinet configuration and runtime are not specified in available evidence for this exact SKU; request a full Vertiv configuration sheet for the MUEXM480-100BAP to confirm battery string options and expected runtime curves at your actual load percentage before purchasing.

This unit is best positioned in facilities with existing 480V three-phase infrastructure — manufacturing plants, hospital mechanical rooms, or medium-scale data centers — where avoiding a 480-to-208V step-down transformer is a design goal and 100kVA covers the protected load with standard industry headroom.
