APC by Schneider Electric Galaxy vs UPS 15KW 400V 1 Internal 7AH Smart Modular - GVSUPS15KB2HS

APC by Schneider Electric GVSUPS15KB2HS Galaxy VS UPS 15kW 400V Expandable 3-Phase Online UPS

Overview

The APC by Schneider Electric GVSUPS15KB2HS is a 15kW (15 kVA) double-conversion online UPS designed for three-phase 400V commercial and industrial installations — data centers, network equipment rooms, medical imaging suites, and industrial automation environments where a momentary power interruption is not an option. Double-conversion topology means the load runs continuously on conditioned inverter output, not on raw utility power with a transfer switch in the path. Voltage irregularities, frequency drift, and waveform distortion are fully isolated from your equipment by design, not by exception. The Galaxy VS ships with one internal 7AH Smart Modular Battery String and is field-expandable, giving you a growth path without replacing the main unit as your runtime requirements change.

Key Features

• Double-Conversion (Online) Topology: The load never touches raw utility power — the inverter provides continuous, synthesized output. Voltage sags, surges, and brownouts that fall between 340V and 460V are corrected silently without switching to battery. This is the right topology for IT hardware, programmable logic controllers, or any load that cannot tolerate even a 4ms transfer gap.
• 15kW / 15 kVA at Unity Power Factor: Rated output is 15,000W, which means you get full kilowatt capacity without a power-factor derating penalty — a meaningful distinction when sizing against server and network equipment that typically presents near-unity loads. No hidden capacity loss here.
• Pure Sine Wave Output: The inverter produces a true sine waveform rather than a stepped approximation. Active power factor correction (APFC) power supplies in servers and switching-mode equipment require sine output to operate correctly and avoid overheating — square or simulated-sine UPS designs can damage these loads over time.
• 0.99 Input Power Factor with 3% Input THD: Drawing current at near-unity input power factor means the GVSUPS15KB2HS puts very little reactive burden on your building electrical system. The 3% input harmonic distortion keeps generator sets and facility transformers happy and reduces the risk of nuisance breaker trips on shared circuits.
• Wide Input Voltage Window (340–460V) at 40–70Hz: This input range accommodates significant utility voltage variation before the unit switches to battery — an important consideration in regions with unstable grid infrastructure or facilities fed from on-site generators that may hunt frequency slightly during transients.
• ECO Mode for Efficiency Gains: When utility power is within tolerance, ECO mode routes the load through a high-efficiency bypass path rather than the full double-conversion inverter chain. This reduces heat generation and operating cost in stable grid environments. When conditions drift outside tolerance, the unit switches to full double-conversion automatically — no manual intervention required.
• 2.5:1 Crest Factor Tolerance: Non-linear loads like variable-frequency drives and switching power supplies draw current in sharp peaks rather than smooth sine waves. A 2.5:1 crest factor rating means the UPS inverter can supply those peak current demands without clipping the waveform or triggering overcurrent protection — critical for mixed IT and industrial load environments.
• Output Voltage THD ≤3%: Sensitive equipment — medical imaging hardware, high-precision instrumentation, industrial controllers — can be disrupted by harmonic distortion on the supply voltage. Holding output THD to 3% under load keeps downstream equipment operating within its design envelope.
• Expandable Smart Modular Battery Architecture: The unit ships with one internal 7AH Smart Modular Battery String. Additional strings can be added in the field to extend runtime without a forklift upgrade or a replacement UPS chassis. This modular approach lets you right-size the initial purchase and expand as the protected load grows or runtime requirements increase.
• Three-Phase Input and Output (27A Max): Configured for three-phase 400V distribution, matching the standard power architecture for European and international commercial facilities, large data center rows, and heavy industrial equipment rooms. The 27A maximum current rating supports the full 15kW load at 400V three-phase.

Integration and Compatibility

The GVSUPS15KB2HS operates on three-phase 400V infrastructure, standard in European commercial and international industrial facilities. The wide input voltage range (340–460V, 40–70Hz) accommodates most regional grid variations and on-site generation sources. The pure sine output is compatible with all active power factor correction (APFC) power supplies, variable-frequency drives, and server platforms. For facilities integrating this unit into a network infrastructure or power management framework, the Galaxy VS platform supports APC's EcoStruxure architecture — consult APC's integration documentation for SNMP, Modbus, and building management system (BMS) connectivity options specific to your firmware version. When planning total protected load, pair this UPS with a properly rated power distribution unit (PDU) matched to the three-phase output configuration. Use our UPS sizing and runtime planning guide to validate runtime estimates against your actual load profile before purchase.

Frequently Asked Questions

Q: What is the difference between the GVSUPS15KB2HS and a standard standby or line-interactive UPS?

A: The GVSUPS15KB2HS uses double-conversion (online) topology. The load runs on inverter-generated power at all times — there is no transfer switch delay when utility power fails or degrades. Standby UPS designs have a 2–10ms transfer gap; line-interactive designs still pass utility power through a filter. For sensitive or mission-critical equipment, double-conversion is the correct choice.

Q: Can the battery capacity be expanded after installation?

A: Yes. The Galaxy VS uses a Smart Modular Battery String architecture. The unit ships with one internal 7AH string; additional strings can be installed in the field to extend runtime without replacing the UPS chassis.

Q: What is ECO mode and when should I use it?

A: ECO mode routes the load through a high-efficiency bypass path when utility power is stable and within tolerance, reducing inverter losses and operating costs. It is appropriate for stable grid environments where efficiency is a priority. In facilities with frequent voltage variations, full double-conversion mode provides maximum protection.

Q: Does this UPS support three-phase input and output?

A: Yes. The GVSUPS15KB2HS is a three-phase in / three-phase out unit rated for 400V distribution, with a maximum input current of 27A. It is intended for commercial and industrial facilities with three-phase power infrastructure, not for single-phase or residential applications.

Q: What input voltage and frequency range does the Galaxy VS accept before switching to battery?

A: The unit accepts input voltage between 340V and 460V and input frequency between 40Hz and 70Hz before transferring to battery. This wide window accommodates most utility voltage variations and on-site generator frequency drift without unnecessary battery cycling.

Q: Is the output waveform suitable for servers and switching-mode power supplies?

A: Yes. The UPS produces a true sine wave output with total harmonic distortion of 3% or less. This is compatible with all active power factor correction (APFC) power supplies found in modern servers, networking equipment, and industrial controllers. Simulated-sine or stepped-waveform UPS designs are not suitable for APFC loads.

The spec I keep coming back to on the GVSUPS15KB2HS is that 0.99 input power factor combined with 3% input THD. On paper those look like minor details — in practice they determine whether your facility electrician signs off on the install or starts asking uncomfortable questions about generator set sizing and harmonic filter requirements. At 15kW, a UPS drawing current at poor power factor or high harmonic content puts real reactive burden on shared building infrastructure. This unit avoids that problem cleanly.

Technical Highlights:

• Double-Conversion Topology: Zero transfer time when utility power fails or goes out of tolerance — the load never sees a break. At 15kW protecting critical infrastructure, a 4ms gap is 4ms too long.
• Wide Input Window (340–460V, 40–70Hz): Handles grid sag down to 340V and frequency variation from 40 to 70Hz before pulling from battery. Generator-fed facilities and regions with unstable utility quality benefit directly — fewer nuisance battery discharges means longer battery service life.
• 2.5:1 Crest Factor: Variable-frequency drives and switching power supplies draw current in sharp peaks. A 2.5:1 crest factor means the inverter supplies those peaks without waveform distortion or overcurrent trips — the spec that separates a data center UPS from an industrial one.

Deployment Considerations:

• This is a three-phase 400V unit — verify your facility distribution panel and downstream PDU are configured for three-phase before specifying. It is not suitable for single-phase North American 120/208V environments without distribution infrastructure changes.
• The 7AH internal battery string provides a starting runtime baseline that may be minimal at full 15kW load. Size your runtime requirements before purchase and plan battery string expansion into your rack or room layout — field-expandable does not mean field-expandable in a crowded cabinet with no clearance.

The GVSUPS15KB2HS is the right specification for European or international commercial facilities protecting three-phase server rows, industrial automation panels, or medical imaging equipment where grid instability is a known factor and runtime flexibility needs to grow with the protected load — not a unit you replace when requirements change.
