Product Overview

The ABB 07KT97, identified by the engineering part number GJR5253000R4270 and also designated as WT97, is a high-performance power supply and basic unit for the Advant Controller 31 (AC31) system. This module serves as the foundational energy source for the AC31 rack, converting primary industrial power into the stabilized internal voltages required by the processor and communication interfaces. Engineered to provide deterministic performance in Distributed Control Systems (DCS), the 07KT97 ensures that control logic execution remains uninterrupted by minor voltage fluctuations. Its robust Swedish design is specifically tailored for longevity in heavy-duty automation cabinets, offering superior resistance to the thermal stress and electrical noise common in high-density industrial environments.
