What’s Built In
Add capacity as the room grows — not before you need it.
- Modular, transformerless design using three-level IGBT topology with a hybrid Silicon Carbide converter
- Integrated maintenance bypass options up to 600kW (400/415/480V) or 150kVA (208V)
- OSHPD (HCAI) OSP-certified — pre-approved for seismic compliance in California’s most demanding facilities
- Hot-swappable lithium-ion or VRLA internal batteries, with optimized external cabinets available
- UL 924 and CSA C22.2 No. 141 certified for centralized emergency lighting (10–120kVA, 208/480V)
Unity power factor delivers more capacity in a smaller footprint.
