APC by Schneider Electric Galaxy vs UPS 40KW 400V for UP to 4 Internal 9AH Smart - GVSUPS40K0B4HS

APC by Schneider Electric GVSUPS40K0B4HS Galaxy VS 40kW 3-Phase Online UPS

Overview

The APC by Schneider Electric GVSUPS40K0B4HS is a 40kW (40 kVA) three-phase, double-conversion online UPS engineered for data centers, large server rooms, and critical infrastructure environments where a sustained, conditioned power supply is non-negotiable. Unlike line-interactive topologies that only intervene on sag or surge events, the Galaxy VS runs in continuous double-conversion mode — incoming AC is rectified to DC, then re-inverted to clean AC — meaning your load never sees raw utility power. Every fluctuation, harmonic distortion, and frequency deviation is scrubbed before it reaches downstream equipment.

This unit is sized for up to four internal 9Ah smart modular battery strings, giving you scalable runtime capacity without requiring an external battery cabinet in smaller deployments. The 400V three-phase architecture makes it a natural fit for European and international electrical installations as well as any North American facility wired to that voltage standard.

Key Features

• Double-Conversion Online Topology: Power flows through rectifier and inverter on every cycle — no transfer time, no exposure to utility-side disturbances. For servers, SAN arrays, and network cores where even a half-cycle voltage dip can trigger a controller fault, this is the topology that eliminates that failure mode entirely.
• 40kW / 40 kVA Output at Unity Power Factor: A 1:1 kW-to-kVA ratio means you can load this UPS to its full 40kW nameplate without derating for power factor — unlike older UPS designs where a 40 kVA unit might only deliver 32kW of real work. Accurate capacity planning from day one.
• ECO Mode for Efficiency Gains: When utility power is within tolerance, ECO mode bypasses the inverter and passes power through with minimal conversion loss. This can meaningfully reduce operating costs in facilities where the grid is stable — though you should confirm your IT equipment tolerates ECO mode's slightly wider voltage window before enabling it for production loads.
• 0.99 Input Power Factor: Drawing current at nearly unity power factor (0.99) minimizes reactive current on your building's electrical infrastructure. Your upstream switchgear, transformers, and distribution panels carry less burden — important in facilities where power factor penalties apply on utility bills or where upstream conductors are already sized tight.
• Wide Input Voltage Range (340–460V): Accepts input across a 120V range without switching to battery, accommodating the voltage swings common in industrial facilities, older buildings, or sites fed by generator sets that regulate less tightly than utility feeds. Less battery cycling means longer battery service life.
• 3-Phase Input and Output: Designed for three-phase distribution — standard for 40kW-class loads. Both input and output are three-phase, so it integrates directly with three-phase PDUs and switchgear without single-phase conversion losses or imbalance concerns.
• Output Voltage Regulation to ±1%: Holds output voltage within 1% of nominal regardless of load swings or input variation. Sensitive electronics — storage controllers, network hardware, precision instrumentation — stay within their design operating window even under dynamic load changes.
• 2.5:1 Crest Factor Capability: Handles loads with high peak-to-RMS current ratios (crest factor up to 2.5:1). Switch-mode power supplies common in server equipment draw current in sharp peaks; a UPS with insufficient crest factor headroom clips those peaks and generates distortion. This unit is sized to handle real-world mixed IT loads without waveform compromise.
• Sine Wave Output: Pure sine wave output — not a stepped approximation — is required by the active PFC front ends found in virtually all modern server PSUs. A modified sine wave UPS would cause those PSUs to run hot, trip overtemperature protection, or fail outright. This unit delivers what modern equipment requires.
• 4,658 BTU/h Heat Dissipation: Plan your cooling allocation accordingly. At full load, this unit contributes roughly 4,658 BTU/h to room heat load — approximately 1.4 tons of cooling capacity. Factor this into your facility's total cooling budget when placing the unit in an existing data hall.
• 72A Maximum Input Current: Size your input circuit breaker and feed conductors for 72A at 400V three-phase. Coordinate with your electrical contractor before installation to confirm upstream protection is correctly rated and that the panel has capacity for this draw.

Integration and Compatibility

The GVSUPS40K0B4HS operates on a 40–70 Hz input frequency range, accommodating both 50Hz and 60Hz utility feeds — useful for facilities that may switch between generator and grid sources operating at slightly different frequencies. Output frequency is selectable at 50 or 60 Hz to match your load requirements. The internal smart battery string architecture (up to four 9Ah strings) supports modular battery replacement without removing the UPS from service, reducing planned maintenance windows. Confirm output voltage configuration (380V or 415V nominal, within the 380–415V output operating range) matches your downstream PDU and load equipment specifications before commissioning.

Frequently Asked Questions

Q: What is the UPS topology of the GVSUPS40K0B4HS?

A: The GVSUPS40K0B4HS uses a double-conversion (online) topology, meaning all connected loads receive power that has been fully rectified and re-inverted on every cycle. There is no transfer time and no exposure to raw utility power under normal or fault conditions.

Q: How many battery strings does this UPS support, and what capacity are they?

A: The GVSUPS40K0B4HS supports up to four internal smart modular battery strings, each rated at 9Ah. The modular design allows battery strings to be added or replaced without taking the UPS offline.

Q: What input voltage range does the GVSUPS40K0B4HS accept?

A: The unit accepts three-phase input voltage between 340V and 460V without switching to battery. This wide range accommodates generator feeds and sites with variable utility voltage, reducing unnecessary battery cycling.

Q: Is ECO mode available on the GVSUPS40K0B4HS, and when should it be used?

A: Yes, ECO mode is available. It bypasses the inverter when utility power is within tolerance, improving operating efficiency. It is best suited for installations where grid quality is consistently high and the connected equipment has been verified to tolerate the slightly wider voltage window ECO mode permits.

Q: What are the output voltage options for the GVSUPS40K0B4HS?

A: The output voltage operating range is 380V to 415V (three-phase), with output voltage regulation held to within 1% of nominal. Confirm your downstream PDU and load equipment input specifications match this range before commissioning.

Q: How much heat does the GVSUPS40K0B4HS generate at full load?

A: At full load, the unit dissipates approximately 4,658 BTU/h. Account for roughly 1.4 tons of additional cooling capacity in your data center or equipment room thermal budget when deploying this UPS.

The GVSUPS40K0B4HS is the model I recommend when a facility needs 40kW of three-phase protected power and wants to avoid the complexity of an external battery cabinet in the initial deployment. The 0.99 input power factor is the spec I flag first for engineers evaluating upstream electrical capacity — at 72A max draw on a near-unity PF, the reactive current overhead is minimal, which matters when you're working with a panel that's already 70–80% loaded.

Technical Highlights:

• Unity Output PF (1.0): Full 40kW real power output at 40 kVA nameplate — no derating calculation needed. You load it to 40kW and get 40kW to your equipment. Older UPS designs at 0.8 PF would cap at 32kW for this frame size.
• 340–460V Input Range: 120V of input headroom means the unit stays on inverter bypass (not battery) through the voltage swings typical of generator-fed or industrial utility feeds. Battery cycles are reserved for actual outages, extending service life.
• ECO Mode: Available for facilities with consistent grid quality. Reduces conversion losses by bypassing the inverter when input is in tolerance. Verify that all connected PSUs tolerate the ECO mode voltage window — active PFC units generally handle it; older ferro-resonant or linear supplies may not.

Deployment Considerations:

• Input circuit protection must be sized for 72A at 400V three-phase. Coordinate the breaker rating and conductor gauge with your electrical contractor before the unit arrives on site — this is not a last-minute item on a data center fit-out schedule.
• Heat dissipation of 4,658 BTU/h is the gotcha most pre-deployment checklists miss. If you're dropping this into an existing room that was cooling 40kW of IT load, your cooling headroom just shrank by 1.4 tons — verify with your facilities team before commissioning.

The GVSUPS40K0B4HS is the right fit for a 400V three-phase data hall or large server room in the 30–40kW load range where the project calls for internal batteries in the initial phase and a clean migration path to additional strings as the load grows — without pulling in an external battery enclosure until the load actually demands it.
