Phoenix Contact QUINT-PS100-240AC/24DC/10 Ruggedized Power Module

Product Overview

Phoenix Contact QUINT-PS100-240AC/24DC/10 Ruggedized Power Module for Harsh Environments

The Phoenix Contact QUINT-PS100-240AC/24DC/10 (Part No. 2938604) is a premium 24 VDC / 10 A DIN rail power supply engineered for continuous, uninterrupted operation in the most demanding industrial environments. Designed under Phoenix Contact’s renowned QUINT POWER series, this unit delivers stable, regulated DC output even under extreme load fluctuations, wide-range AC input variations, and severe electromagnetic interference — making it the backbone power source for mission-critical automation systems worldwide.

Whether deployed in a petrochemical control cabinet, a mining site’s distributed control system, or a water treatment plant’s PLC panel, the QUINT-PS100-240AC/24DC/10 maintains output integrity where conventional power supplies fail. Its active power boost capability — delivering up to 200% rated current for 12 ms — ensures reliable startup of capacitive and inductive loads without nuisance tripping, a critical advantage when powering Siemens S7-300/S7-400 PLC racks, Rockwell Allen-Bradley ControlLogix I/O chassis, or Schneider Electric Modicon M340 backplanes.

Comprehensive Protection Solutions

In modern industrial automation, a power supply is only as reliable as the system it supports. The QUINT-PS100-240AC/24DC/10 is routinely deployed alongside a carefully selected ecosystem of protective and control components to form a complete, fault-tolerant architecture.

Within the same control cabinet, the QUINT-PS100-240AC/24DC/10 typically powers Phoenix Contact QUINT-DIODE/40AC/2X20/1X40 redundancy modules, enabling seamless load sharing and failover between dual PSU configurations — a standard requirement in SIL 2 safety-rated systems. For load distribution and selective protection, Phoenix Contact QUINT-FUSE/24DC/20 electronic circuit breakers are installed downstream, providing zone-selective isolation without affecting the entire 24 VDC bus.

On the control side, this PSU reliably powers Phoenix Contact ILC 151 ETH inline controllers and AXC F 2152 PLCnext Technology controllers, both of which demand stable, low-ripple 24 VDC for deterministic real-time processing. For I/O expansion, Phoenix Contact Axioline F and Inline I/O modules — including digital input/output, analog, and safety I/O variants — draw their operating power directly from this supply rail.

Communication integrity is equally dependent on clean power. Phoenix Contact FL SWITCH 2008 managed industrial Ethernet switches and RAD-900-IFS wireless I/O modules are commonly co-located in the same panel, all powered from the QUINT 24 VDC rail. For safety-rated applications, Phoenix Contact PSR-SCP-24DC/ESD/5X1/1X2 safety relays and PSR-TRISAFE safety controllers operate on the same bus, ensuring that emergency stop, light curtain, and door interlock circuits receive uninterrupted, monitored power.

Terminal connectivity is handled by Phoenix Contact CLIPLINE complete terminal blocks — specifically the PT 2,5 and UK 5 N series — which provide vibration-resistant, push-in connections rated for the full operating temperature range of the QUINT PSU. This integrated approach — from power input to field device — ensures that every component in the control architecture benefits from the QUINT’s robust power delivery.

Application in Critical Infrastructure

The QUINT-PS100-240AC/24DC/10 has established a strong track record across the world’s most demanding industrial sectors. In oil and gas upstream and midstream facilities, it powers wellhead control panels and pipeline SCADA RTUs where ambient temperatures routinely exceed 55 °C and voltage transients from large motor starts are common. Its surge immunity (EN 61000-4-5, 2 kV line-to-earth) and wide input range absorb grid instabilities without output interruption.

In underground mining operations, where humidity can reach 95% RH and fine coal or mineral dust permeates every enclosure, the QUINT PSU’s sealed power stage and conformal-coated PCB options provide the corrosion resistance needed for multi-year service intervals. Continuous production lines in steel and metallurgy plants rely on this unit to sustain 24/7 operation of rolling mill drive controllers, furnace temperature regulators, and ladle crane automation systems — environments where a power supply failure translates directly into costly production downtime.

Water and wastewater treatment facilities deploy the QUINT-PS100-240AC/24DC/10 in remote pump station panels, where it must operate reliably across seasonal temperature swings and withstand the corrosive atmosphere generated by chlorination and aeration processes. In power generation — both conventional thermal and renewable — it supplies protection relay panels, turbine control systems, and substation automation equipment, where IEC 61850 communication modules and numerical relays demand rock-solid DC power with minimal ripple.

Across all these sectors, the QUINT-PS100-240AC/24DC/10 serves not only as a primary power source but also as a critical spare part for maintenance teams. Its standardized DIN rail form factor and universal input range make it a direct drop-in replacement for aging or failed PSUs across multiple generations of control system hardware, reducing mean time to repair (MTTR) and supporting long-term plant availability strategies.

Security & Quality FAQ

Q1: What does the 12-month warranty cover?
All units supplied by TOPNLMS carry a 12-month warranty from the date of shipment. Coverage includes manufacturing defects, premature component failure, and output specification non-conformance. In the event of a warranty claim, we provide advance replacement or full refund after fault verification. Our warranty process is documented and traceable, supporting your plant’s maintenance records.

Q2: How is each unit tested before shipment?
Every QUINT-PS100-240AC/24DC/10 unit undergoes a pre-shipment functional test covering output voltage accuracy, load regulation, current limiting behavior, and DC OK relay operation. Units sourced from authorized distribution channels are accompanied by original manufacturer documentation. Refurbished or surplus units — clearly identified as such — undergo extended burn-in testing and are supplied with a full test report.

Q3: Is this unit compatible with my existing Phoenix Contact QUINT system?
Yes. The QUINT-PS100-240AC/24DC/10 (2938604) is fully compatible with Phoenix Contact’s QUINT POWER ecosystem, including QUINT-DIODE redundancy modules, QUINT-UPS uninterruptible power supply modules, and QUINT-CHECK monitoring devices. It is also electrically compatible with any 24 VDC load previously powered by earlier QUINT-PS or MINI-PS series units of equivalent rating, making it a reliable upgrade or replacement option.

Q4: Can you support long-term or repeat procurement for maintenance programs?
Absolutely. TOPNLMS maintains buffer stock of high-demand Phoenix Contact QUINT POWER modules to support planned maintenance schedules, annual spare parts programs, and emergency breakdown orders. We offer volume pricing for standing orders and can provide lead-time commitments aligned with your plant’s maintenance windows. Contact our team to discuss a tailored supply agreement.
