APC by Schneider Electric Galaxy vs Maintenance Bypass Cabinet with Output Transformer - GVSBPOT100

APC by Schneider Electric GVSBPOT100 Galaxy VS Maintenance Bypass Cabinet with Output Transformer 60–100KW

Overview

The GVSBPOT100 is a freestanding maintenance bypass cabinet purpose-built for the APC Galaxy VS UPS platform, covering 60–100KW loads at 480V input. Its integrated step-down output transformer converts the 480V supply to 208V output — eliminating the need for a separate transformer enclosure in data centers or industrial facilities where the distribution infrastructure runs at 480V but critical loads (servers, network gear, automation equipment) require 208V. This is the right cabinet when you need bypass capability and voltage transformation in a single, code-compliant footprint.

At 600mm wide × 836mm deep × 1485mm tall, the GVSBPOT100 fits in standard power and UPS infrastructure rows without requiring a custom bay. The white freestanding enclosure installs alongside the Galaxy VS UPS frame, and the integrated bypass path means UPS maintenance or replacement can be performed without dropping protected loads — critical in 24/7 operations where any unplanned downtime has direct business impact.

Key Features

• 480V Input / 208V Output Transformer: The onboard step-down transformer handles the voltage conversion internally — no external transformer cabinet, no additional floor space, no separate wiring coordination. For facilities fed at 480V (typical in North American commercial and industrial construction), this collapses two line items into one and simplifies the single-line diagram significantly.
• 60–100KW Bypass Range: Sized for mid-to-large critical loads. A single GVSBPOT100 supports the full Galaxy VS capacity range in this power class, so you're not specifying a bypass cabinet that undercuts the UPS it's protecting.
• Freestanding Enclosure — 600 × 836 × 1485mm: The footprint fits standard row-based deployments. At 836mm depth, verify aisle clearance before finalizing placement — front and rear access clearances for UPS and bypass accessories are code-driven in most jurisdictions.
• Maintenance Bypass Path: The core function: isolate the Galaxy VS UPS from the load circuit for scheduled maintenance or emergency replacement while protected equipment stays online. In 24/7 data center and manufacturing environments, this is table stakes — specifying a UPS without a bypass cabinet in this power class is an operational risk most facilities managers won't accept.
• REACH and RoHS Compliance: Both certifications are verified for this SKU. RoHS restricts hazardous substances (lead, mercury, cadmium, etc.) — relevant for EU deployments and for enterprise procurement programs with environmental sustainability requirements. REACH compliance addresses chemical safety under EU regulation. Neither certification constrains the unit's electrical performance, but both are often required on procurement checklists for government, healthcare, and multinational enterprise buyers.
• Operating Temperature 0–40°C: Standard commercial equipment room range. If the installation site runs hot (poorly cooled plant floor, outdoor enclosure, high-altitude location), verify the ambient against this ceiling — bypass cabinets generate heat under load and the transformer adds to that thermal budget.
• Operating Humidity 0–95% (non-condensing): Wide humidity tolerance covers most controlled indoor environments. Condensing conditions are the concern — if the cabinet will experience temperature cycling (e.g., near loading dock doors in winter climates), ensure the installation space is properly conditioned.
• Storage Ratings -25 to 55°C / 0–95% RH: Broad storage envelope matters for pre-deployment staging. If the cabinet will sit in a warehouse or staging area before install, these bounds prevent damage during shipping and storage in non-climate-controlled environments.

Integration and Compatibility

The GVSBPOT100 is designed for use with the APC Galaxy VS UPS platform in the 60–100KW range. The 480V input aligns with North American commercial distribution at the 480V/277V level, and the 208V output feeds standard IT and commercial load panels. When specifying this cabinet, confirm the Galaxy VS UPS frame rating matches the 60–100KW window — the bypass cabinet must be rated at or above the connected UPS output to avoid a capacity mismatch at the bypass path.

Physical installation requires coordination with the facility's electrical contractor: 480V input terminations, output wiring to the load panel, and the Galaxy VS interconnect must all be sized and terminated per the installation guide. The 675kg shipping weight (package dimensions 990 × 800 × 1670mm) means rigging and floor-loading calculations should be completed before the unit arrives on site. Confirm the raised floor or concrete slab load rating accommodates the installed weight of the cabinet plus any conduit and cable management overhead.

Frequently Asked Questions

Q: What UPS platform is the GVSBPOT100 designed to work with?

A: The GVSBPOT100 is designed for the APC Galaxy VS UPS platform, covering the 60–100KW capacity range. It provides a maintenance bypass path so the Galaxy VS can be serviced or replaced without dropping protected loads.

Q: What voltage conversion does the built-in transformer provide?

A: The integrated output transformer steps down 480V input to 208V output. This is useful in facilities where the distribution infrastructure runs at 480V but the connected IT or commercial loads require 208V — eliminating the need for a separate external transformer enclosure.

Q: What are the physical dimensions of the GVSBPOT100?

A: The cabinet measures 600mm wide × 836mm deep × 1485mm tall. The shipping package is 990mm wide × 800mm deep × 1670mm tall, and the packaged weight is 675kg — rigging and floor-load planning are required before delivery.

Q: Is the GVSBPOT100 RoHS and REACH compliant?

A: Yes. The GVSBPOT100 carries both RoHS and REACH compliance certifications, which restrict hazardous substances and address chemical safety under EU regulations. These certifications are commonly required by enterprise, government, and healthcare procurement programs.

Q: What are the operating environment requirements for the GVSBPOT100?

A: The cabinet is rated for 0–40°C operating temperature and 0–95% relative humidity (non-condensing). Storage ratings extend to -25–55°C and 0–95% RH. It is a freestanding unit intended for installation in controlled indoor environments such as data centers, equipment rooms, and industrial facilities.

A: No. The GVSBPOT100 is a bypass cabinet accessory designed to work in conjunction with the Galaxy VS UPS platform. It does not function as a standalone power conditioning or UPS device.

Jerry Tildsen

The GVSBPOT100 solves a specific and common infrastructure problem: facilities fed at 480V that need to protect 208V loads with a Galaxy VS UPS. The integrated step-down transformer is what separates this cabinet from a standard bypass — instead of coordinating a separate transformer enclosure, an electrician, and additional floor space, you get a single freestanding footprint at 600 × 836 × 1485mm that handles both bypass switching and voltage conversion. That matters when you're tight on row space in a data center or working within a fixed mechanical room layout.

Technical Highlights:

• 480V → 208V Integrated Transformer: Collapses two enclosures into one — the bypass cabinet and the step-down transformer. Significant for single-line diagram simplicity and floor space budgeting in new construction or retrofit projects.
• 60–100KW Bypass Range: Matches the Galaxy VS capacity window at this power class. The bypass path must be rated to match or exceed the UPS output — this unit is correctly sized so you won't encounter a derating mismatch at the bypass.
• RoHS + REACH Certified: Both verified for this SKU. Required checkboxes for EU deployments, government procurement, and many enterprise sustainability programs. Won't slow down a compliant bid.

Deployment Considerations:

• The 675kg packaged weight means you need a rigging plan before delivery day — confirm floor load ratings (raised floor tiles and structural slab) before placement, and coordinate with your electrical contractor on conduit routing for the 480V input feed and 208V output terminations.
• Operating temperature ceiling is 40°C. In plant floor or telecom room installations with marginal HVAC, the transformer's heat contribution under full load can push ambient above this threshold — verify thermal budget before commissioning.

The GVSBPOT100 is the right specification for a greenfield data center or critical manufacturing facility where the building distribution runs at 480V, the critical load infrastructure is 208V, and the Galaxy VS is already on the single-line. It's not a general-purpose bypass cabinet — it's purpose-built for that 480V-to-208V Galaxy VS deployment scenario.
