APC by Schneider Electric GVSBPIT75 Galaxy VS Maintenance Bypass Cabinet with Input Transformer 75kW
Overview
The GVSBPIT75 is a freestanding maintenance bypass cabinet purpose-built for the APC Galaxy VS UPS platform, designed to let data center and industrial facility operators isolate the UPS for servicing without dropping the critical load. Rated at 75kW with an integrated input transformer, it bridges high-distribution voltages — 480V or 600V — down to the 208V that downstream IT and process loads actually run on, eliminating the need for a separate step-down transformer in the power path.
At 600mm wide and 1,485mm tall, the GVSBPIT75 fits within a standard floor tile footprint, making it practical for raised-floor data centers where space is allocated in 600mm grid increments. If you're designing a Galaxy VS deployment and your facility feeds 480V or 600V from the switchgear, this cabinet is the component that closes that voltage gap while adding bypass capability in a single enclosure.
Key Features
- 480V or 600V Input Acceptance: The integrated input transformer handles either 480V or 600V feed voltage, outputting 208V to the load. This dual-input range means the same cabinet can be deployed in North American facilities running either distribution voltage without sourcing a separate transformer — one fewer enclosure, one fewer connection point in the power path.
- Maintenance Bypass Functionality: The bypass path allows the upstream Galaxy VS UPS to be completely de-energized and serviced while the critical load continues drawing utility power through the cabinet. For 24/7 environments where scheduled UPS maintenance would otherwise mean a planned outage, this is the architectural feature that makes zero-downtime servicing possible.
- Freestanding Installation: The cabinet stands independently at 1,485mm tall × 600mm wide × 836mm deep — no wall anchoring or rack integration required. This simplifies installation in machine rooms and industrial spaces where wall mounting or open-frame rack installation isn't practical near high-voltage equipment.
- 0–40°C Operating Range: Rated for continuous operation from 0°C up to 40°C, which covers the majority of conditioned data center and equipment room environments (ASHRAE A1/A2 thermal classes). The storage range extends to -25°C / +55°C, so the unit ships safely in cold-climate freight without thermal risk.
- 0–3,000m Altitude Rating: Qualified up to 3,000 meters above sea level — relevant for facilities in high-altitude regions (Denver, Mexico City, mountainous industrial sites) where reduced air density can derate other power components. Verify the Galaxy VS UPS itself carries the same altitude rating for a consistent system spec.
- REACH / RoHS / WEEE Compliance: All three EU compliance marks are verified for this SKU. RoHS restricts hazardous substances in the hardware itself; REACH covers chemical substance documentation in the supply chain; WEEE covers end-of-life disposal obligations. For enterprise procurement teams with EU regulatory requirements or ESG reporting obligations, these are documentation checkboxes that come pre-cleared.
- White Enclosure Finish: The white powder-coat finish is consistent with APC Galaxy VS family aesthetics, which matters when bypass cabinets are co-located with UPS units in customer-visible or executive data center environments where visual consistency is a procurement requirement.
Integration & Compatibility
The GVSBPIT75 is engineered for the APC Galaxy VS UPS family. The input transformer's 480V/600V-to-208V conversion integrates directly into Galaxy VS power distribution architecture — verify the Galaxy VS unit rating and model compatibility with APC documentation before specifying. The 75kW capacity must be matched to the UPS module capacity; oversizing or undersizing the bypass cabinet relative to the UPS output creates both a design gap and a potential code issue depending on jurisdiction.
For facilities teams planning a full power and UPS infrastructure deployment, the bypass cabinet pairs with matching Galaxy VS UPS units and APC's power distribution units. Review the Galaxy VS system APC by Schneider Electric product family documentation to confirm enclosure interconnect requirements, cable sizing for 480V or 600V input feeds, and any required accessories not included with this cabinet.
Frequently Asked Questions
Q: What UPS family is the GVSBPIT75 compatible with?
A: The GVSBPIT75 is designed for the APC Galaxy VS UPS platform. Verify specific model compatibility against APC Galaxy VS system documentation before finalizing your design.
Q: Does the GVSBPIT75 include the input transformer, or is that a separate accessory?
A: Yes — the input transformer is integrated into this cabinet. The GVSBPIT75 accepts 480V or 600V input and outputs 208V, eliminating the need for a separately sourced step-down transformer in the power path.
Q: What is the power capacity of the GVSBPIT75?
A: The GVSBPIT75 is rated at 75kW. Size the bypass cabinet to match your Galaxy VS UPS module capacity to ensure correct system design.
Q: Can the GVSBPIT75 operate at high altitudes?
A: Yes. It is rated for altitudes up to 3,000 meters above sea level, which covers most high-altitude data center and industrial facility installations.
Q: Is the GVSBPIT75 RoHS and REACH compliant?
A: Yes. The GVSBPIT75 carries REACH, RoHS, and WEEE compliance certifications, which satisfies EU regulatory and enterprise ESG procurement requirements.
Q: What are the physical dimensions of the GVSBPIT75?
A: The cabinet is 600mm wide × 836mm deep × 1,485mm tall. It is freestanding and does not require wall mounting or rack integration. Packaged dimensions are 838.2mm × 965.2mm × 1,676.4mm for freight planning.
The thing I want integrators to notice first about the GVSBPIT75 is the integrated input transformer — that single design decision is what separates this cabinet from a basic bypass switch. In a 480V or 600V distribution environment, you'd otherwise be sourcing and installing a separate dry-type transformer to get to 208V for the Galaxy VS system. Here it's folded into the bypass cabinet footprint, which simplifies the single-line diagram, reduces enclosure count, and keeps the 600mm floor-tile alignment intact.
Technical Highlights:
- Dual Input Voltage (480V / 600V): One SKU supports both North American high-distribution voltages. If you're bidding across multiple facilities with different utility feeds, you don't need to specify two part numbers — the GVSBPIT75 covers both, reducing procurement complexity and spare-parts inventory.
- 75kW Bypass Capacity: Sized for mid-to-large Galaxy VS deployments. This isn't a small-room UPS accessory — at 75kW it's appropriate for mid-tier data halls, industrial process loads, and critical facility UPS rooms where the ability to pull the UPS for maintenance without dropping the load is an operational requirement, not an option.
- 0–3,000m Altitude Rating: This spec matters more than it looks. High-altitude facilities in Colorado, the Mountain West, and Latin American markets regularly see derating issues with power equipment not rated above 1,000m. At 3,000m the GVSBPIT75 is spec'd for nearly all inhabited elevations without derating conversations.
Deployment Considerations:
- Confirm the paired Galaxy VS UPS module is also rated for your input voltage (480V or 600V). The transformer in this cabinet handles the conversion on the bypass path — but the UPS module itself has its own input voltage specification that must be matched independently.
- Packaged dimensions (838.2mm × 965.2mm × 1,676.4mm) exceed the cabinet footprint by a meaningful margin — account for this when planning freight access through doorways and elevator dimensions on the delivery route. This is a common site-access gotcha on large power equipment.
For a 480V-fed critical facility deploying Galaxy VS UPS infrastructure where maintenance access without load interruption is a hard requirement, the GVSBPIT75 is the component that makes the architecture work as designed.
