Phoenix Contact QUINT-PS/1AC/24DC/10 QUINT Power Supply

Description

Overview

The Phoenix Contact QUINT Power power supply, model QUINT-PS/1AC/24DC/10, is a primary-switched DIN-rail power supply that converts a single-phase 100–240 V AC mains input into a regulated 24 V DC / 10 A output for control panels, PLC racks, and instrumentation loops. Built around SFB Technology (Selective Fuse Breaking), the QUINT Power series is engineered to trip standard downstream circuit breakers quickly and selectively during a fault, so a short circuit on one output branch does not bring down the entire control system. This makes the QUINT Power family a preferred choice wherever plant uptime and fault isolation matter more than the lowest unit cost.

As the official authorized partner and exclusive regional representative for Phoenix Contact, Seven Star LLC proudly supplies the QUINT Power power supply to industrial and process facilities across the Sultanate of Oman and the wider GCC. Panel builders and EPC contractors in Muscat, Sohar, and Salalah specify the QUINT-PS/1AC/24DC/10 for its combination of adjustable output voltage, high efficiency, and static POWER BOOST reserve current, which together simplify sizing for panels that must start heavy inductive loads such as contactors and solenoid valve banks. Every unit shipped by Seven Star LLC carries full manufacturer traceability, warranty coverage, and access to regional technical support.

Operating Principle

The QUINT-PS/1AC/24DC/10 uses a primary-switched-mode topology: incoming AC mains is rectified, converted to a high-frequency switching waveform, stepped down through a compact transformer, and rectified again to produce a stable, tightly regulated 24 V DC output, adjustable between roughly 18 V DC and 29.5 V DC to compensate for cable voltage drop on long field runs. The Phoenix Contact QUINT-PS/1AC/24DC/10 achieves this because the switching stage operates at high frequency, the power supply achieves high conversion efficiency and a compact footprint compared to older linear designs, while active power-factor correction keeps mains current draw low and clean.

SFB Technology is the defining operating principle of the QUINT Power range: during a downstream short circuit, the unit briefly delivers up to six times its rated current for a few milliseconds, which is enough to magnetically and instantly trip a standard miniature circuit breaker on the faulted branch – without shutting down the healthy branches sharing the same 24 V DC bus. The static POWER BOOST feature works in the opposite direction for normal operation, supplying a controlled current reserve above the nameplate rating for a limited time so that inrush currents from contactors, motor starters, and solenoid valves do not trigger a nuisance shutdown. The practical consequence for the panel designer is a single power supply that behaves predictably under both fault conditions and everyday inrush loading, reducing the number of breakers, fuses, and oversized supplies needed in the cabinet.

Engineering Design of the Phoenix Contact QUINT-PS/1AC/24DC/10

The QUINT Power QUINT-PS/1AC/24DC/10 is housed in Phoenix Contact’s compact grey polycarbonate DIN-rail enclosure, designed for snap-mount installation on standard 35 mm rail inside the control cabinet. Front-facing status LEDs indicate DC OK and output status at a glance, while a potentiometer allows fine adjustment of the output voltage during commissioning to compensate for wiring losses on remote I/O or field-mounted equipment. Pluggable screw-type connection terminals allow the unit to be pre-wired and swapped without disturbing adjacent terminal blocks, minimizing downtime during maintenance or replacement.

Convection cooling with no internal fan keeps the design maintenance-free and suited to the dusty, high-ambient-temperature conditions typical of GCC electrical rooms and outdoor enclosures, with a rated operating range that extends well beyond standard office electronics. An integrated DC OK relay contact and analog signal output provide remote status monitoring back to the PLC or SCADA system, so operators can see supply health without opening the panel door. The unit meets ISA G3 Harsh Group A environmental testing and carries UL, CE, and other approvals relevant to industrial and hazardous-adjacent installations across process and utility applications.

Key Features

The Phoenix Contact QUINT-PS/1AC/24DC/10 power supply is specified across control panel and automation projects for the following reasons, and engineers comparing panel power options frequently standardize on the Phoenix Contact QUINT-PS/1AC/24DC/10 for these traits:

  • On the Phoenix Contact QUINT-PS/1AC/24DC/10, SFB Technology selectively and rapidly trips downstream circuit breakers during a fault, isolating problems to a single branch circuit.
  • Static POWER BOOST current reserve reliably starts contactors, solenoid valves, and motor starters without triggering shutdown.
  • The Phoenix Contact QUINT-PS/1AC/24DC/10 offers adjustable output from approximately 18 V DC to 29.5 V DC compensates for voltage drop on long cable runs to remote I/O.
  • The Phoenix Contact QUINT-PS/1AC/24DC/10 combines high conversion efficiency and convection cooling eliminate the need for a fan while reducing cabinet heat load.
  • On the Phoenix Contact QUINT-PS/1AC/24DC/10, pluggable screw connection terminals allow fast, tool-minimal replacement without disturbing neighboring field wiring.
  • DC OK relay contact and analog output give remote visibility of power supply health to the PLC or SCADA system.
  • Compact DIN-rail housing meets ISA G3 Harsh Group A testing for demanding industrial and process environments.
  • Wide 100–240 V AC input range accepts single-phase mains variation common across GCC grid connections.

Industrial Applications

The QUINT Power QUINT-PS/1AC/24DC/10 supplies, and the Phoenix Contact QUINT-PS/1AC/24DC/10 in particular delivers, 24 V DC control power for PLC racks, remote I/O panels, HMI displays, and instrumentation loops across oil & gas processing, water and wastewater treatment, power distribution substations, and district cooling plants. Its SFB-based fault-selective behavior is particularly valued in large motor control centers and RO desalination skids, where a short circuit on one instrument loop must not interrupt power to the rest of the panel – a requirement that keeps critical pumps, valves, and safety systems running while the fault is isolated and repaired.

As the officially authorized partner for Phoenix Contact, Seven Star LLC distributes the QUINT-PS/1AC/24DC/10 power supply to EPC contractors, panel builders, and plant maintenance teams throughout Oman and the GCC, supporting projects in the Sohar and Salalah industrial and free zones as well as facilities across Muscat, Duqm, and the wider Gulf region. Regional stockholding and factory-backed technical support allow control system integrators to specify the QUINT Power range with confidence that replacement units and application engineering assistance are available locally rather than only through European distribution channels.

Frequently Asked Questions

What does SFB Technology do in the QUINT-PS/1AC/24DC/10 power supply?
SFB Technology (Selective Fuse Breaking) briefly delivers up to six times rated current during a short circuit so that only the faulted branch circuit breaker trips, keeping the rest of the 24 V DC bus and connected equipment running.
How much installation effort and downtime does the QUINT Power design save compared to a linear supply?
Pluggable screw connection terminals and DIN-rail mounting let panel builders pre-wire the unit and swap it in seconds without disturbing neighboring terminals, while the static POWER BOOST reserve removes the need to oversize the supply just to start inductive loads.
What output voltage range and current does the QUINT-PS/1AC/24DC/10 support?
The unit delivers a 24 V DC output adjustable from approximately 18 V DC to 29.5 V DC at up to 10 A, allowing engineers to compensate for voltage drop on long cable runs to remote I/O or field instrumentation.
