APC by Schneider Electric GVSBPOT50B Galaxy VS Maintenance Bypass Cabinet with Output Transformer
Overview
The GVSBPOT50B is a 50 kW maintenance bypass cabinet designed specifically for APC by Schneider Electric Galaxy VS UPS systems operating in mixed-voltage facilities. Its defining role: it accepts 480V AC input and steps that down to 208V AC output via an integrated output transformer, which means critical loads keep running at 208V even during a full UPS bypass — no separate step-down transformer required, no service window where the load goes unprotected. At 1,168 lb installed and standing 58.5 inches tall, this cabinet is engineered for data center and industrial electrical rooms where a bypass event needs to be clean, safe, and invisible to the downstream equipment. If you're commissioning a power and UPS infrastructure around Galaxy VS units in a facility that runs 480V distribution but 208V utilization, the GVSBPOT50B closes that voltage gap at the bypass stage rather than forcing a separate transformer into the single-line diagram.
Key Features
- 50 kW Load Capacity: Rated to carry the full 50 kW load of a Galaxy VS UPS during bypass, so you can perform scheduled or emergency UPS maintenance without shedding any load or staging a temporary power path. That's the entire point of a maintenance bypass — the GVSBPOT50B is sized to handle it without compromise.
- 480V AC Input / 208V AC Output: The integrated output transformer handles the voltage conversion internally. In facilities where utility or generator feed comes in at 480V but server and network loads run at 208V, this eliminates a separate transformer cabinet from the floor plan — one enclosure handles the bypass switching and the voltage step-down simultaneously.
- Purpose-Built for APC Galaxy VS UPS Systems: Designed to integrate directly with the Galaxy VS UPS family, the GVSBPOT50B connects into the existing single-line without requiring custom engineering. Compatibility is with APC UPS equipment — this is not a universal bypass cabinet and should not be applied to other UPS platforms.
