Overview

The Phoenix Contact QUINT‑PS/1AC/12DC/15 (Part No. 2866718) is a primary‑switched DIN‑rail power supply designed for industrial automation systems. Part of the QUINT POWER series, it is known for maximum functionality, preventive monitoring, and high reliability.

Key features include Selective Fuse Breaking (SFB) technology, which allows circuit breakers to trip quickly and selectively at six times the nominal current, isolating defective current paths without affecting the rest of the system.

Additionally, the power supply incorporates POWER BOOST static reserve to reliably start heavy loads and preventive function monitoring to report critical operating states before failures occur, thereby increasing system uptime.

Technical Data

Typical Applications

• Industrial automation panels requiring reliable 12 V DC power distribution.

• Process control systems where preventive monitoring ensures uptime.

• Machine building where heavy loads must be started safely using POWER BOOST.

• Energy systems needing selective fuse protection to isolate faults.

Example: OEMs often use this supply to power PLCs, sensors, and actuators in harsh industrial environments.
