APC by Schneider Electric GVSUPS50KFS-A 50kW Three-Phase UPS for External Batteries
Overview
The APC by Schneider Electric Galaxy VS UPS GVSUPS50KFS-A is a 50kW (50 kVA) three-phase uninterruptible power supply engineered for enterprise data centers, commercial facilities, and critical infrastructure environments where a power interruption is not an option. This unit ships with startup services (5x8) included and is configured to pair with external battery cabinets — giving your deployment team the flexibility to size runtime independently of the UPS chassis. If you're spec'ing power protection for a mid-size data hall, a centralized security operations center, or a large-scale networked surveillance infrastructure, the GVSUPS50KFS-A (often searched as GVSUPS50KFS A) lands in a practical capacity range that doesn't require paralleling multiple smaller units to hit your load target.
The Galaxy VS family sits in commercial-grade UPS systems that bridge the gap between small IT closet units and full enterprise modular frames. It's a fixed-capacity, three-phase design — purpose-built for loads that need true sine wave output, hardwired three-phase input/output, and remote monitoring via SNMP or Modbus without additional cards required.
Key Features
- 50kW / 50 kVA Capacity: Supports substantial three-phase loads — a typical mid-size server room running 30–40 kW of active IT equipment fits comfortably within this envelope with headroom for growth. No need to parallel two smaller UPS units and manage synchronization complexity.
- True Sine Wave Output: Delivers a pure sine wave at 200V, 208V, or 220V AC — critical for active PFC power supplies in modern servers, storage arrays, and networking equipment. Stepped approximation waveforms from cheaper UPS designs can trip PFC-sensitive loads; this unit avoids that failure mode entirely.
- 230V AC Input, 177–239V AC Range: The input accepts a wide voltage range (177–239V AC), which means the unit can ride through browndowns and minor grid fluctuations without switching to battery — preserving battery life for actual outages. Three-phase hardwired input (3PH + N + G) means this is a permanent installation, not a plug-in device.
- External Battery Architecture: Runtime is determined entirely by the external battery cabinets you commission alongside this unit — not by internal battery modules with fixed capacity. This is the correct architecture for deployments where you need 30+ minutes of runtime at full load, or where battery replacement logistics favor a separate enclosure.
- 480V DC Bus Voltage: The 480V DC battery bus allows longer battery strings with fewer parallel strings, reducing the number of battery connections and simplifying maintenance. Higher DC bus voltage also improves efficiency at partial loads.
- SNMP / Modbus Remote Monitoring: Network management is built in — no additional management card required for basic SNMP or Modbus polling. This integrates directly into existing DCIM platforms, BMS systems, or SNMP trap receivers, giving your operations team visibility into UPS status, load percentage, and battery state without a truck roll.
- 65 dB(A) Sound Emission: At 65 dB(A), this unit is quieter than many comparable three-phase UPS designs — a relevant consideration if it shares space with operations staff or is installed in an open equipment room rather than a dedicated UPS alcove.
- Operating Range Up to 40°C (104°F): Rated to operate at up to 40°C ambient, which covers most non-air-conditioned equipment rooms and warmer data center environments. Above 40°C, derate or improve room cooling before deployment.
- 3,152W Thermal Dissipation: At full load, the unit dissipates approximately 3.15 kW of heat. Factor this into your room cooling calculations — a 3-ton supplemental cooling unit is a reasonable minimum pairing for a sealed equipment room housing this UPS at full load.
- REACH and RoHS Compliant: Both REACH and RoHS environmental compliance are verified for this SKU — relevant for enterprise procurement teams with EU supply-chain reporting obligations or sustainability mandates.
Integration and Compatibility
The GVSUPS50KFS-A uses hardwired three-phase connections on both input and output (Hard Wire 5-wire: 3PH + N + G), making it a permanent installation requiring a licensed electrician for commissioning — plan for this in your project schedule. The included startup service (5x8, business hours) covers initial system verification, which is standard for equipment in this power class.
For network infrastructure and large-scale physical security deployments — including high-density PoE switch stacks, NVR clusters, and access control head-end equipment — this UPS provides the three-phase power protection backbone that keeps the entire system online during utility events. Pair it with an appropriately sized APC by Schneider Electric external battery cabinet to dial in your required runtime.
SNMP and Modbus integration allows the GVSUPS50KFS-A to report into most enterprise power management and DCIM platforms without proprietary software. Verify your NMS supports the APC MIB or Modbus register map for full telemetry — load, battery voltage, estimated runtime, and alarm states are all accessible remotely.
Frequently Asked Questions
Q: What output voltages does the GVSUPS50KFS-A support?
A: The GVSUPS50KFS-A supports three output voltage settings: 200V AC, 208V AC, and 220V AC. Output is three-phase hardwired (3PH + N + G). Select the correct output voltage during commissioning to match your connected load equipment.
Q: Does the GVSUPS50KFS-A include internal batteries?
A: No. The GVSUPS50KFS-A is configured for external batteries only — runtime depends entirely on the external battery cabinets you install alongside this unit. This gives you full control over runtime sizing independent of the UPS chassis.
Q: What is the warranty on the GVSUPS50KFS-A?
A: The GVSUPS50KFS-A carries a 1-year manufacturer warranty.
Q: Does the GVSUPS50KFS-A require an additional network management card for SNMP monitoring?
A: No additional card is required for basic SNMP or Modbus remote monitoring — network management capability is built into the unit. Verify your NMS supports the APC MIB or Modbus register map for full integration.
Q: What is the maximum operating temperature for the GVSUPS50KFS-A?
A: The maximum operating temperature is 40°C (104°F). Operating above this threshold requires derating or improved room cooling. Storage temperature range is -25°C to 55°C (-13°F to 131°F).
Q: What input voltage and frequency does the GVSUPS50KFS-A accept?
A: The unit accepts 230V AC nominal input with a range of 177–239V AC, and an input frequency of 70 Hz. Input connection is three-phase hardwired (3PH + N + G) and requires a licensed electrician for installation.
The GVSUPS50KFS-A is the version of the Galaxy VS you spec when the load is real and runtime needs to be engineered separately from the UPS chassis. That external-battery-only architecture is the right call for a 50kW deployment — you're not going to get meaningful runtime from internal modules at this power level anyway, and sizing external cabinets to your actual runtime requirement (say, 15 minutes at 50kW vs. 45 minutes) is a conversation you have with your battery vendor, not a hardware swap on the UPS itself. The 480V DC bus on this unit is a detail worth flagging: higher DC bus voltage means longer battery strings, fewer parallel connections, and a simpler maintenance picture over the life of the installation.
Technical Highlights:
- 50kW / 50 kVA at 208V Three-Phase: Enough capacity to support a dense mid-size server room or a large physical security head-end — NVR clusters, PoE switch stacks, access control servers, and workstations — without paralleling UPS units. Simplifies single-point monitoring.
- 177–239V AC Input Range: The wide input range keeps the unit on utility power through browndowns, which protects battery cycle count over time. Batteries last longer when the UPS isn't switching to them on every minor grid dip.
- Built-in SNMP/Modbus: Remote monitoring without an add-on card means lower total cost and one fewer failure point. SNMP trap integration into an existing NMS is straightforward — load level, battery status, and alarms are all accessible remotely from day one.
Deployment Considerations:
- Hardwired 5-wire three-phase input and output (3PH + N + G) means you need a licensed electrician on-site for both installation and any future service — build that into your project timeline and budget. This is not a plug-in device.
- Thermal dissipation at full load is 3,152W. If this UPS shares a sealed equipment room with your IT gear, verify your room cooling budget accounts for that heat load before commissioning — undersized HVAC is the most common commissioning oversight on units in this power class.
Best fit: a mid-size enterprise data center or a large physical security operations center where three-phase power is already available, runtime flexibility is a priority, and the operations team needs remote visibility into UPS health without deploying additional management hardware.
