APC by Schneider Electric GVSBPIT50 50kW Maintenance Bypass Cabinet with Input Transformer
Overview
The GVSBPIT50 is a Galaxy VS series maintenance bypass cabinet built for critical power environments where 50 kW of load capacity needs to stay live during UPS servicing. Dual input voltage support — 480 V AC and 600 V AC — steps down to a 208 V AC output via an integrated input transformer, making this the right hardware when your facility supply doesn't match downstream UPS voltage requirements. At 530 kg and standing 58.46 inches tall, this is a purpose-built data center or industrial floor component, not a field improvisation. Explore the full APC by Schneider Electric power portfolio for complementary Galaxy VS UPS systems and distribution accessories.
Key Features
- 50 kW Load Capacity: Handles high-density compute or industrial critical loads at full bypass — if your UPS needs maintenance and you can't take the load down, 50 kW of continuous bypass capacity keeps operations running without shedding load or staggering transfers.
- Dual Input Voltage (480 V AC / 600 V AC): Accepts both 480 V and 600 V facility supply, which matters in mixed-voltage plants or when Canadian 600 V distribution feeds a 208 V downstream bus. The integrated input transformer handles the step-down — no separate transformer cabinet required.
- 208 V AC Output: Delivers standard 208 V AC to the UPS or PDU chain, aligning directly with most North American three-phase IT load configurations including server racks, storage arrays, and networking equipment.
- Maintenance Bypass Function: The core purpose here is operational continuity — technicians can isolate and service the Galaxy VS UPS without dropping the critical load. For 24/7 facilities where planned downtime doesn't exist, this is a non-negotiable part of the power architecture.
- RoHS and REACH Compliant: Meets both EU RoHS and REACH environmental directives — relevant for deployments subject to environmental procurement mandates or multinational compliance requirements.
- Galaxy VS System Integration: Designed to integrate directly with Galaxy VS UPS systems — not a universal bypass enclosure. Match to your Galaxy VS frame to ensure mechanical and electrical compatibility without field modification.
- Data Center Form Factor: At 23.62 inches wide, 32.91 inches deep, and 58.46 inches tall, the cabinet fits standard data center floor layouts. The white finish integrates cleanly into raised-floor environments where consistent equipment aesthetics matter to facilities teams.
Integration and Compatibility
The GVSBPIT50 is engineered specifically for APC Galaxy VS UPS platforms. Verify your Galaxy VS model number against APC's system configuration guides before ordering — bypass cabinets in this family are not universally cross-compatible across frame sizes or kW ratings. For facilities planning purposes, factor the 530 kg shipping weight into floor loading calculations and confirm elevator or loading dock capacity before scheduling delivery. Internal links to power protection planning resources can help scope the full distribution architecture before cabinet selection.
Frequently Asked Questions
Q: What UPS systems is the GVSBPIT50 compatible with?
A: The GVSBPIT50 is designed for use with APC Galaxy VS UPS systems. Verify compatibility with your specific Galaxy VS model and kW rating against APC's configuration documentation before ordering.
Q: What input voltages does the GVSBPIT50 support?
A: The GVSBPIT50 accepts 480 V AC and 600 V AC input, stepping down to 208 V AC output via an integrated input transformer.
Q: What is the load capacity of the GVSBPIT50?
A: The GVSBPIT50 supports a 50 kW load capacity, suitable for high-density data center or industrial critical power applications.
Q: Is the GVSBPIT50 RoHS compliant?
A: Yes. The GVSBPIT50 carries both RoHS and REACH environmental compliance certifications.
Q: What are the physical dimensions and weight of the GVSBPIT50?
A: The cabinet measures 58.46 inches tall, 23.62 inches wide, and 32.91 inches deep. Shipping weight is 530 kg — factor floor loading and access logistics into your installation plan.
The GVSBPIT50 addresses a specific gap in Galaxy VS deployments: facilities running 480 V or 600 V distribution that need to feed a 208 V UPS bus without a standalone transformer cabinet. The integrated input transformer is the differentiator here — it consolidates what would otherwise be two separate enclosures into one floor footprint, and at 50 kW bypass capacity, it covers the load range where most mid-to-large data hall UPS frames sit.
Technical Highlights:
- Dual Input Voltage (480/600 V AC): Covers both US 480 V and Canadian 600 V facility standards in a single SKU — useful for multi-site operators who want consistent hardware across mixed-voltage campuses.
- 50 kW Bypass Capacity: Matched to Galaxy VS frames in this power class; attempting to use this cabinet with a significantly larger UPS frame will leave load headroom on the table or create a configuration mismatch.
- 208 V AC Output: Aligns directly with three-phase 208 V IT distribution, the predominant bus voltage in North American enterprise data centers — no secondary conversion step required downstream.
Deployment Considerations:
- At 530 kg, pre-delivery floor loading verification is mandatory — most raised-floor tiles are rated 1,000–2,000 lbs distributed, but point loads from cabinet feet require an independent structural review before placement.
- This is a Galaxy VS-specific component, not a universal bypass cabinet. Confirm your Galaxy VS frame model and kW rating match before placing the order — APC's system configuration matrix is the authoritative reference.
The GVSBPIT50 is the right call for a 480 V or 600 V-fed data center that needs Galaxy VS UPS maintainability without adding a standalone step-down transformer to the floor plan. If your facility runs 208/240 V input directly, you likely need a different bypass variant in the Galaxy VS family.
