Phoenix Contact QUINT-PS/1AC/48DC/10 2866682 Industrial Power Supply

Phoenix Contact QUINT-PS/1AC/48DC/10 2866682: Industrial Data Link Power for Smart Factory Networks

The Phoenix Contact QUINT-PS/1AC/48DC/10 2866682 is a high-performance 48 VDC / 10 A DIN rail power supply engineered for the demanding power integrity requirements of modern industrial communication networks. As smart factories evolve toward fully connected architectures — where field devices, PLC controllers, remote I/O modules, HMI panels, SCADA gateways, variable frequency drives, and edge computing nodes must exchange data without interruption — stable, conditioned DC power is the invisible backbone that makes it all possible. The QUINT-PS/1AC/48DC/10 2866682 delivers precisely that: clean, regulated 48 VDC output with active power boost, SFB (Selective Fuse Breaking) technology, and continuous self-monitoring to keep every node in your industrial network alive and communicating.

Compatibility & Integration Notes

Connected Automation Data Flow

In a typical smart factory deployment, the QUINT-PS/1AC/48DC/10 2866682 sits at the heart of the control cabinet power rail, supplying stable 48 VDC to a chain of interconnected automation components. Consider a production line where a Siemens S7-1500 PLC orchestrates motion control and process logic: the PLC communicates over PROFINET to a Phoenix Contact AXL F BK PN Axioline F bus coupler, which in turn distributes I/O signals to distributed sensor and actuator modules. Each of these nodes depends on a clean, uninterrupted 48 VDC supply — exactly what the QUINT-PS/1AC/48DC/10 delivers, with its active power boost ensuring that even during cold-start inrush events, the bus coupler and its attached I/O slices remain powered and communicating.

Moving upstream in the data flow, a Phoenix Contact FL SWITCH 2008 managed industrial Ethernet switch aggregates PROFINET traffic from multiple field segments and forwards it to the plant SCADA server running Wonderware System Platform or Ignition SCADA. The switch itself, along with co-located Phoenix Contact FL COMSERVER UNI 232/422/485 serial-to-Ethernet gateways, relies on the same 48 VDC power rail. These gateways bridge legacy Modbus RTU devices — such as older variable frequency drives and flow meters — into the modern Modbus TCP network, ensuring no data island is left behind.

At the drive level, Danfoss FC 302 or ABB ACS880 variable frequency drives receive speed and torque setpoints via PROFIBUS DP or EtherNet/IP, with their control electronics powered through 24 VDC or 48 VDC auxiliary supplies derived from the same QUINT power segment. Proximity sensors, pressure transmitters, and IO-Link masters connected to Balluff BNI IOL-302 IO-Link masters feed real-time process values back through the network. An HMS Anybus X-gateway handles protocol translation between EtherNet/IP and PROFIBUS DP segments, while a Moxa EDS-510A managed switch provides the fiber uplink to the control room, all powered and monitored within the same 48 VDC distribution architecture anchored by the QUINT-PS/1AC/48DC/10 2866682.

The built-in DC OK relay output of the QUINT-PS/1AC/48DC/10 feeds a digital input on the PLC or a dedicated alarm module, enabling the SCADA system to receive real-time power health alerts. This closes the loop on remote diagnostics: operators at the HMI or SCADA workstation can monitor power rail status, acknowledge alarms, and dispatch maintenance — all without stepping onto the factory floor.

Solving Data Isolation in Industrial Sites

One of the most persistent challenges in industrial automation is the coexistence of multiple communication protocols across different generations of equipment. A plant may run PROFIBUS DP on legacy machinery, PROFINET on newer PLC islands, and Modbus TCP on energy meters and HVAC controllers — each segment historically isolated, creating data silos that prevent plant-wide transparency and predictive maintenance.

The QUINT-PS/1AC/48DC/10 2866682 addresses this challenge not by converting protocols itself, but by providing the stable, high-quality 48 VDC power that protocol gateways, managed switches, and edge computing devices require to operate reliably 24/7. When power quality is compromised — through voltage sags, ripple, or transient spikes — protocol converters and communication modules reset unexpectedly, causing data gaps, false alarms, and production stoppages. The QUINT series’ SFB technology delivers up to 3× rated current for 12 ms to blow downstream fuses selectively, isolating faults without taking down the entire power rail and the communication network it supports.

For remote monitoring and system expansion, the QUINT-PS/1AC/48DC/10’s signaling output integrates directly with SCADA alarm management systems, enabling condition-based maintenance workflows. As production lines expand — adding new robot cells, conveyor segments, or quality inspection stations — additional 48 VDC loads can be added to the power rail within the unit’s rated capacity, or a second QUINT unit can be paralleled for redundancy using the Phoenix Contact QUINT-ORING/24DC/2X10/1X20 diode module, ensuring zero-downtime power architecture for mission-critical communication infrastructure.

Pre-shipment functional testing, availability confirmed by RFQ availability, and a warranty terms confirmed during quotation make the QUINT-PS/1AC/48DC/10 2866682 a reliable procurement choice for system integrators, panel builders, and MRO buyers who cannot afford communication downtime on the factory floor.

Industrial Connectivity FAQ

Q1: Does the QUINT-PS/1AC/48DC/10 2866682 support PROFINET or EtherNet/IP network segments directly?
A: The QUINT-PS/1AC/48DC/10 2866682 is a power supply, not a communication device itself. However, it is specifically designed to power PROFINET, EtherNet/IP, PROFIBUS DP, Modbus TCP/RTU, and DeviceNet network nodes — including PLCs, managed switches, protocol gateways, and remote I/O modules — with the stable 48 VDC they require for uninterrupted communication. Its DC OK relay output can be integrated into SCADA alarm systems for real-time power health monitoring.

Q2: How does the SFB technology affect network stability during fault conditions?
A: Phoenix Contact’s Selective Fuse Breaking (SFB) technology allows the QUINT-PS/1AC/48DC/10 to deliver up to 3× its rated output current (up to 30 A) for 12 ms during a downstream short circuit. This selectively blows the branch fuse of the faulted circuit while keeping all other branches — and their associated communication nodes — powered and online. The result is that a single wiring fault does not cascade into a network-wide communication outage.

Q3: Can this power supply be used in redundant power architectures for SCADA or DCS systems?
A: Yes. The QUINT-PS/1AC/48DC/10 2866682 supports parallel redundancy when combined with a Phoenix Contact QUINT-ORING diode module. Two QUINT units can feed a common 48 VDC bus; if one unit fails, the other seamlessly takes over without any interruption to the communication network. This architecture is recommended for SCADA servers, historian nodes, and critical HMI power rails where uptime is non-negotiable.

Q4: What warranty and pre-shipment testing does this unit include?
A: Every QUINT-PS/1AC/48DC/10 2866682 supplied by ZYPLC comes with a warranty terms confirmed during quotation and is functionally tested before shipment to verify output voltage, current regulation, SFB operation, and DC OK signal integrity.
