ABB SA168 (3BSE003389R1) is a dedicated industrial power supply that converts universal AC input (90–250V) into a tightly regulated 24V DC output at up to 25A (600W). Built for ABB Advant OCS and Master DCS systems, it powers system controllers, I/O subracks, and associated field equipment.

The unit features high‑efficiency conversion with low ripple and noise, reinforced input‑to‑output isolation, and complete protection against overload, short‑circuit, overvoltage, and overtemperature. A built‑in 10A fuse (5672827‑10) enhances circuit safety. The rugged 19‑inch rack‑mount enclosure (IP20) suits standard control cabinets, while fan‑assisted cooling ensures stable performance under heavy load.

Modular and maintenance‑friendly, the SA168 supports redundancy when used with SA168K kits, maximizing uptime in critical automation networks. It complies with CE, UL, and relevant industrial standards, with RoHS exemption for use in high‑reliability installations.
