Transformer-less 3-phase UPS, 10-50 kVA, 0.9 pf, up to 95.5% efficiency, parallel capability up to 20 units for maximum scalability and redundancy.
The ABB PowerScale 33 is a transformerless three-phase online double-conversion UPS designed for small to mid-size data centers, industrial processes, and critical building services. It delivers high efficiency, a compact footprint, and an excellent balance of performance and affordability.
Rated from 10 to 50 kVA with paralleling up to four units, the PowerScale 33 offers scalable power protection that grows with the business. Its robust design and proven reliability make it a popular choice for healthcare, manufacturing, and commercial IT rooms.
Up to 96% online efficiency and higher still in eco mode reduces electricity costs and heat rejection, improving PUE and lowering operating expense.
Up to four units can be paralleled for capacity or redundancy, allowing infrastructure to grow with demand without ripping and replacing existing investments.
A transformerless design keeps the UPS small and light, freeing valuable floor space and simplifying installation in tight electrical rooms.
A graphical color touch display, multilingual menus, and full suite of communication options (SNMP, Modbus, dry contacts) make the UPS easy to commission, monitor, and service.
