High-performance 3-phase UPS, 60-500 kW, unity power factor, 96% online efficiency, scalable to 5 MW with up to 10 units in parallel.
The ABB PowerWave 33 is a premium three-phase online UPS for medium and large data centers, industrial plants, and mission-critical infrastructure. It combines class-leading efficiency, excellent input power factor, and low input current distortion — delivering high availability while minimizing impact on the upstream electrical system.
Ranging from 60 to 500 kVA with parallel expansion, the PowerWave 33 is engineered for installations where uptime, efficiency, and power quality all matter equally. It is particularly at home in colocation sites, financial services, and healthcare campuses.
Up to 96.5% efficiency in double-conversion mode and up to 99% in Xtra VFI mode cuts energy waste dramatically, translating directly to lower operating costs and reduced carbon footprint.
Unity input power factor and input current distortion below 3% minimize upstream wiring, transformer, and generator oversizing, reducing capital cost and improving system reliability.
Parallel configurations support N+1, N+N, and distributed architectures, delivering the tier-level availability required by mission-critical operations.
A bright graphical touchscreen, comprehensive network and protocol support, and predictive diagnostics give operators the insight they need to maintain peak performance.
