NOW HIRING: Production Electronics Technicians

40kVA Power Conversion System

With a compact, 2.5U form factor, the transformerless OZPCS-RS40 power conversion system installs directly into equipment and Li-ion battery racks. Front-side terminations simplify interconnect and the fully parallelable, 40kW architecture supports system modularity and enables easy field upgrades.

Offering wide 208-480 VAC and 330-820 VDC operating ranges, grid-connected and grid-forming operating modes, advanced “smart inverter” features and design and certification for energy storage applications, system design doesn’t get any easier.
