B300 Three Phase Modular UPS for the 400 Vac Grid

Info & Details

The B300 three phase modular UPS for the 400Vac grid offers true online double-conversion topology and Gamatronic’s modular architecture with parallel system capability for easy scaling up to 1200kVA/kW. The system is comprised of lightweight hot swappable 30kVA/kW AC power modules. The system provides reliable high performance power assurance for medium to large sized critical loads with a small space-saving footprint thanks to its high power density. The B300 can be scaled up to 300kVA/kW per system and can expand in parallel up to 1200kVA/kW.


  • Modular design enables simple and easy scalability on site without disconnecting the UPS from the load or transferring to bypass
  • Minimal servicing due to lightweight hot-swappable modules, removable critical components and fail-safe system controller
  • Constant operational availability of your mission critical loads as modules are controlled independently and can be replaced within minutes while the unit is still running
