Product overview
The RM33 Series is a heavy-duty, industrial-frequency online 3:3 UPS designed for capacities from
300 kVA to 800 kVA. It employs highly reliable thyristor phase-controlled rectifiers and IGBT inverter
technology for maximum reliability, and features three-phase input and output with a built-in output
isolation transformer. Engineered for mission-critical operations in docks, mines, highways, and other
harsh or high-temperature environments.
