PHOENIX CONTACT QUINT-PS/1AC/48DC/5 Primary-Switched Power Supply – QUINT Series
When a 48 VDC power supply fails on the production floor, the consequences cascade instantly — PLCs lose power, field devices go offline, safety circuits drop out, and an entire automated line grinds to a halt. Unplanned downtime in industrial environments costs thousands of dollars per minute, and the root cause is often a power supply that was never engineered for the demands of continuous industrial operation. The PHOENIX CONTACT QUINT-PS/1AC/48DC/5 (Order No. 2866679) eliminates this risk with a design philosophy built around reliability, diagnostics, and uninterrupted power delivery.
Within the QUINT product family — Phoenix Contact’s flagship line of primary-switched power supplies — the QUINT-PS/1AC/48DC/5 occupies a critical niche: it delivers a regulated 48 VDC output at 5 A (240 W) from a single-phase AC input, making it the preferred choice for 48 V bus architectures in telecommunications infrastructure, process automation, and distributed control systems. Globally, the QUINT series is recognized as an industry benchmark for DIN-rail power supplies, trusted by system integrators and OEMs across more than 100 countries.
