The ABB PowerValue 31TX is a 5-10 kVA transformer-based online double conversion UPS with 3-phase input and single-phase output. It features unity power factor (kVA = kW), up to 91% efficiency, and supports paralleling up to four units for 40 kVA capacity or redundancy. The all-in-one design includes built-in MBS, circuit breakers, backfeed protection, and high-quality copper winding transformer.
The ABB PowerValue 31TX is a single-phase, online double-conversion UPS with a built-in isolation transformer, engineered for environments that demand galvanic isolation, long autonomy, and strict power quality. Its transformer-based design makes it a go-to choice for medical imaging, laboratory equipment, and industrial control systems.
Rated from 10 to 20 kVA in a robust tower form factor, the PowerValue 31TX combines proven reliability with a wide input window, accepting three-phase input and delivering protected single-phase output. It is a natural fit where compatibility with long cable runs, noisy mains, and harsh environments is essential.
An integrated output transformer creates a clean electrical barrier between mains and load, strongly attenuating common-mode noise and meeting isolation requirements for medical and industrial users.
Three-phase input with a wide voltage window handles unstable grids and long cable runs, while the single-phase output matches the needs of sensitive and legacy equipment.
Support for large external battery cabinets provides extended autonomy for sites where utility outages can last minutes to hours, or where generator run-up time must be bridged.
Serviceable components, clear diagnostics, and comprehensive communications simplify on-site maintenance and reduce mean time to repair in mission-critical deployments.
