APC by Schneider Electric GVMPB160KHS Galaxy VM 160 kVA Parallel UPS with Backfeed Protection

Overview

The APC by Schneider Electric GVMPB160KHS is a 160 kVA (144 kW) three-phase, online double-conversion UPS engineered for large commercial and industrial power protection — data centers, industrial facilities, healthcare systems, and critical infrastructure where a power event is simply not an option. The Galaxy VM platform supports parallel operation, meaning you can deploy multiple units in a parallel-redundancy or capacity-scaling configuration without introducing a single point of failure into your power topology. Backfeed protection is built in, a requirement on most utility-grade and generator-fed installations. Startup is covered under the 5x8 service tier included with this SKU.

Unlike smaller UPS units that serve individual racks or workgroups, the GVMPB160KHS operates at the facility or room level — it's wired directly into your electrical infrastructure via hardwired terminal connections, not plug-and-play outlets.

Key Features

• 160 kVA / 144 kW Output Capacity: At unity power factor (1.0 input PF), you get the full 144,000 W of real power — no derating penalty between apparent and real power output. That matters when sizing for high-PF IT loads like modern server PSUs, which eliminates the undersizing guesswork common with older 0.8 PF-era UPS sizing.
• Online Double-Conversion Topology: The load runs off the inverter continuously — not off raw utility power with a transfer switch. That means zero transfer time on utility failure and complete isolation from upstream voltage sags, spikes, and frequency drift. For sensitive industrial controls or financial transaction systems, this is the topology to specify.
• Wide Input Voltage Range (250–600 V): The GVMPB160KHS accepts input from 250 V up to 600 V, giving it flexibility across international grid voltages and generator output ranges. On sites with variable generator output — common during startup ramp — this prevents nuisance battery transfers that shorten battery service life.
• Output Voltage Range (380–415 V): Regulated output holds between 380 and 415 V regardless of input fluctuation, keeping downstream equipment within spec even when the utility is drifting or a generator is hunting for frequency stability.
• 40–70 Hz Input Frequency Tolerance: Accepts input frequencies from 40 to 70 Hz, making it compatible with generator sets that hunt outside standard 50/60 Hz tolerances during transient load changes. In generator-primary sites, this tolerance prevents unnecessary battery engagement.
• Pure Sine Wave Output at <3% THD: Output total harmonic distortion stays under 3%, which matters for motor-driven loads, medical imaging equipment, and precision industrial controls that degrade or fault on distorted waveforms. Most UPS units in this class advertise <5% THD — this spec is tighter.
• Parallel Architecture with Backfeed Protection: The parallel-capable design lets you combine units for N+1 redundancy or scale capacity without a forklift upgrade. Integrated backfeed protection meets the safety requirements of most utility interconnection standards — critical when your UPS sits between a generator and a utility tie.
• Maximum Output Current 262 A: At the rated 400 V output, the 262 A maximum current capacity gives you the headroom to feed large PDU branches or multiple distribution panels without pushing the unit to its current ceiling.
• Web-Based Management: Remote monitoring and management via web interface keeps your facilities team out of the mechanical room for routine checks. Integration with enterprise UPS monitoring platforms and building management systems is supported — important for facilities running centralized DCIM or BMS dashboards.
• Audible Alarm System: On-unit audible alarms provide local notification for utility failure, battery low, overload, and fault conditions — a code requirement in many jurisdictions for unattended mechanical rooms.
• 65 dB Acoustic Level: At 65 dB, this unit produces roughly the same noise level as a standard office conversation. Acceptable for a dedicated UPS room, but factor it into planning if the installation is adjacent to occupied workspace in a warehouse or clinic environment.
• Hardwire-Only Termination: Output connections are hardwired 4-wire (3PH + G) and 5-wire (3PH + N + G) — no NEMA outlets. This is standard for utility-class UPS installations and ensures the connection is handled by a licensed electrician during commissioning, which most local codes require at this power level anyway.

Integration and Compatibility

The GVMPB160KHS fits into three-phase UPS deployments alongside APC's Galaxy VM family, allowing you to extend or restructure your power protection as load grows. The hardwired terminal input accepts power from utility feeds or generator sets within the 250–600 V input range, making it compatible with North American 480 V and European 400 V distribution architectures. Web-based management supports integration with data center infrastructure management (DCIM) software and building automation systems. For facilities teams evaluating parallel UPS configurations, consult your electrical engineer on bus bar sizing and backfeed relay coordination — the built-in backfeed protection handles the UPS side, but upstream coordination remains a site engineering responsibility.

If you're planning a complete power protection stack, pair this unit with compatible APC by Schneider Electric power distribution and managed network switches for remote monitoring of your downstream infrastructure.

The GVMPB160KHS sits at the heavy end of the Galaxy VM line — 160 kVA, parallel-capable, with backfeed protection baked in. What catches my attention on this unit is the unity power factor input spec: you're getting 144 kW of real power out of 160 kVA, which eliminates the capacity-derating math that trips up facilities teams sizing against server PSU loads. That's a meaningful operational advantage over legacy 0.8 PF UPS designs still common in older data centers.

Technical Highlights:

• Unity Input Power Factor (1.0): Full 144,000 W real power delivery with no apparent-to-real power derating — directly reduces the number of units required in a parallel array for a given load target.
• Sub-3% Output THD: Tighter than the industry-standard 5% THD ceiling; relevant for mixed loads combining server infrastructure with precision manufacturing controls or medical imaging on the same bus.
• 250–600 V Input Range: Covers both 400 V European distribution and 480 V North American feeds in a single SKU, plus generator output variance during transients — eliminates nuisance battery cycling in generator-primary facilities.

Deployment Considerations:

• All connections are hardwired terminal blocks — budget for licensed electrical contractor time at commissioning; this is not a self-install unit. The 5x8 startup service included with this SKU covers initial commissioning support during business hours only; if your timeline requires weekend or after-hours energization, verify service tier coverage in advance.
• At 65 dB acoustic output, placement adjacent to occupied office space or patient areas in healthcare facilities requires acoustic planning — a dedicated mechanical room or equipment closet is the appropriate installation environment.

The GVMPB160KHS is the right specification for a medium-to-large data center row, a multi-tenant colocation pod, or an industrial manufacturing facility running PLCs and SCADA infrastructure where you need genuine parallel redundancy at the 144 kW tier without sourcing and integrating a separate backfeed protection assembly.
