APC by Schneider Electric G35TSBPXFM10K30G Galaxy 3500 Input Transformer
The APC by Schneider Electric G35TSBPXFM10K30G is a floor-mounted input transformer designed for the APC by Schneider Electric Galaxy 3500 UPS series, stepping 480V input power down to 208V to match the UPS's internal voltage requirements. This is a purpose-built infrastructure component for data centers, critical facilities, and enterprise power rooms where the available building supply is 480V three-phase but the downstream uninterruptible power supply system requires 208V input.
Overview
Installing the G35TSBPXFM10K30G between your 480V distribution panel and a Galaxy 3500 UPS eliminates the need to run a separate 208V utility feed to the UPS location — a meaningful cost avoidance in facilities where 480V is the standard distribution voltage. The transformer is floor-mounted and sized to integrate directly into the Galaxy 3500 footprint, with overall dimensions of 58.5 in. H × 14.02 in. W × 32.99 in. D. That tall, narrow profile is worth noting during space planning: the unit requires adequate vertical clearance and floor load capacity consistent with transformer-class equipment.
Key Features
- 480V to 208V step-down: Matches 480V building distribution to the Galaxy 3500 UPS input requirement — lets you deploy the UPS in a 480V facility without a separate transformer infrastructure project.
- Galaxy 3500 Series integration: Engineered specifically for the Galaxy 3500 platform, so mechanical fit, electrical interface, and serviceability align with APC's documented installation requirements for this UPS family.
- Floor-mount form factor: Stands 58.5 in. tall with a 14.02 in. × 32.99 in. footprint — plan for floor reinforcement appropriate to transformer weight and verify aisle clearance before placement.
Integration & Compatibility
The G35TSBPXFM10K30G is a Galaxy 3500 Series accessory transformer. Verify your specific Galaxy 3500 model's input transformer requirements against APC's power distribution documentation before ordering — Galaxy 3500 variants differ by kVA rating and may require matched transformer models. Consult APC's installation guide for conduit entry points, torque specifications on terminal connections, and required clearances around the enclosure for thermal management and NEC compliance.
Frequently Asked Questions
Q: What UPS is the G35TSBPXFM10K30G designed for?
A: The G35TSBPXFM10K30G is an input transformer built for the APC Galaxy 3500 UPS series, stepping 480V input down to 208V for the UPS system.
Q: What are the input and output voltages?
A: Input voltage is 480V; output voltage is 208V.
Q: What are the physical dimensions of the G35TSBPXFM10K30G?
A: The unit measures 58.5 in. H × 14.02 in. W × 32.99 in. D and is floor-mounted.
Q: Can this transformer be wall-mounted?
A: No. The G35TSBPXFM10K30G is specified as a floor-mount unit only.
The G35TSBPXFM10K30G solves a specific and common data center infrastructure mismatch: facilities built around 480V three-phase distribution that need to feed a Galaxy 3500 UPS rated for 208V input. Rather than pulling a new 208V utility circuit — which typically means a new transformer at the panel, conduit runs, and coordination with the electrical contractor — this unit drops in between the 480V feed and the UPS, handling the step-down locally. The 58.5-inch height means you're working with a significant floor-standing unit, not a rack accessory.
Technical Highlights:
- 480V Input: Accepts the 480V three-phase supply common in commercial and industrial facilities, eliminating the need for a separate step-down at the distribution panel for this UPS circuit.
- 208V Output: Delivers the 208V supply required by the Galaxy 3500 UPS platform — the voltage match is not negotiable; the UPS will not accept 480V direct.
- Floor-Mount Profile: At 58.5 in. H × 14.02 in. W × 32.99 in. D, the footprint is narrow but tall — plan floor load ratings and verify top clearance before finalizing placement in a low-ceiling mechanical room or raised-floor data center.
Deployment Considerations:
- Confirm the kVA rating of this transformer matches your specific Galaxy 3500 UPS model before ordering — Galaxy 3500 systems are available in multiple kVA tiers and require matched transformer models; a mismatch will result in undersized or incompatible infrastructure.
- NEC and local code will govern minimum clearances around the transformer enclosure; coordinate with your electrical engineer on conduit entry, conductor sizing for 480V primary, and grounding before scheduling installation.
The G35TSBPXFM10K30G is the correct choice when you're deploying a Galaxy 3500 UPS in a 480V-distribution data center or critical facility and need a factory-matched step-down solution rather than a field-engineered workaround — particularly in new construction or major infrastructure refresh projects where the electrical scope is already open.
