QUINT-PS-3X400-500AC/24DC/30 2938633 Product Description

In modern smart factory environments, stable and intelligent power delivery is the invisible backbone of every data link. The Phoenix Contact QUINT-PS-3X400-500AC/24DC/30 (Part No. 2938633) is a 3-phase, 24VDC/30A DIN-rail mounted power supply engineered to sustain uninterrupted energy flow across the full industrial communication chain — from field-level sensors and actuators through PLC controllers, remote I/O modules, HMI panels, SCADA gateways, and edge computing nodes up to enterprise MES and ERP systems.

Unlike conventional PSUs, the QUINT series integrates active power boost and preventive function monitoring, enabling the power supply itself to participate in the factory's diagnostic data loop. When paired with Phoenix Contact's QUINT-DIODE/40AC/2X20DC redundancy modules, the system delivers N+1 redundant power architecture — a prerequisite for continuous 24/7 production lines where any millisecond of downtime translates directly to throughput loss.

The QUINT-PS-3X400-500AC/24DC/30 anchors the 24VDC power rail that energizes the entire field-to-cloud data pathway. At the field level, distributed Phoenix Contact Axioline F remote I/O modules collect analog and digital signals from pressure transmitters, flow meters, and proximity sensors. These I/O nodes communicate upstream via PROFINET to a Siemens S7-1500 PLC or Phoenix Contact RFC 4072S controller, where real-time process logic executes at sub-millisecond cycle times.

The PLC's Ethernet port connects to an industrial managed switch — such as the Phoenix Contact FL SWITCH 2008 — which segments the factory network into deterministic PROFINET rings and standard Ethernet segments. This switch architecture ensures that time-sensitive automation traffic is isolated from general IT traffic, preserving cycle-time integrity even as data volumes scale.

From the switch backbone, data flows to Phoenix Contact mGuard RS4000 industrial security routers that enforce firewall policies and VPN tunnels for secure remote access. Maintenance engineers can connect from off-site to diagnose PLC faults, review I/O status, and push firmware updates — all without physical site access. This remote diagnostic capability is only possible when the underlying 24VDC power rail, supplied by the QUINT-PS-3X400-500AC/24DC/30, remains stable under varying load conditions.

At the SCADA and visualization layer, Phoenix Contact CHARX control modular HMI panels and third-party SCADA servers running Ignition by Inductive Automation or Wonderware System Platform subscribe to OPC-UA data feeds published by the PLC. The QUINT PSU's signal contact output feeds a discrete input on the PLC, so any power anomaly — voltage sag, overload, or thermal warning — is immediately logged as an alarm event in the SCADA historian, triggering operator notifications and automated load-shedding routines.

Variable frequency drives such as the Phoenix Contact CONTACTRON motor management modules and third-party VFDs draw their control-circuit power from the same 24VDC bus. The QUINT's active power boost (60 A for 5 seconds) handles the inrush current spikes generated when multiple drives start simultaneously, preventing nuisance tripping that would otherwise corrupt in-progress batch records.

Edge computing nodes — including Phoenix Contact PLCnext Control AXC F 2152 — run containerized analytics applications that process vibration FFT data, energy consumption trends, and OEE calculations locally before forwarding compressed summaries to cloud platforms via MQTT or REST APIs. The QUINT PSU's wide input range (400–500 VAC, 3-phase) makes it equally suitable for European 400V grids and North American 480V industrial services, simplifying global deployment of standardized smart factory templates.

Protocol fragmentation is one of the most persistent challenges in brownfield automation upgrades. Legacy Modbus RTU devices, newer PROFINET nodes, and cloud-bound OPC-UA endpoints often coexist on the same production floor. The QUINT-PS-3X400-500AC/24DC/30 does not itself perform protocol conversion, but its reliable 24VDC output powers the protocol gateway modules — such as the Phoenix Contact GW PB DP/MODBUS TCP — that bridge these incompatible worlds. Without a stable power source, gateway dropouts create data islands: segments of the plant that become invisible to SCADA, breaking alarm chains and distorting KPI dashboards.

Remote monitoring gaps are addressed through the PSU's built-in signal contact. By wiring this relay output to a spare DI on the PLC or a standalone Phoenix Contact MINI MCR signal conditioner, operations teams receive real-time power health telemetry alongside process data. This eliminates the blind spot where a power supply degrades silently over weeks before causing an unplanned shutdown.

Production line transparency improves when every node in the data chain — sensors, I/O, controllers, drives, and HMIs — operates from a power source with predictable, monitored output. The QUINT series' SFB (Selective Fuse Breaking) technology ensures that a short circuit on one branch does not collapse the entire 24VDC bus, preserving data continuity on unaffected segments during fault isolation.

System scalability is built into the QUINT architecture. Additional QUINT-PS units can be paralleled using the QUINT-DIODE redundancy module to expand current capacity as new automation islands are added — without redesigning the power distribution cabinet or interrupting existing production.

All units supplied by NANKMOS undergo pre-shipment functional testing: output voltage verification, boost current validation, and signal contact continuity check. Stock is maintained for rapid dispatch, and every unit carries a 12-Month Warranty covering manufacturing defects and performance deviations from published specifications.

Q1: Does the QUINT-PS-3X400-500AC/24DC/30 support PROFINET or EtherNet/IP communication directly?The PSU itself does not have an Ethernet port; it provides the stable 24VDC power rail that energizes PROFINET and EtherNet/IP devices — PLCs, managed switches, remote I/O, and gateways — in the network. Its signal contact output can be wired to a PLC digital input to report power status over any fieldbus the PLC supports.

Q2: How does the active power boost feature affect network stability during motor starts?The 60 A / 5-second boost absorbs inrush current from simultaneously starting drives and contactors, preventing voltage dips on the 24VDC bus. Voltage dips below ~18 VDC can cause managed switches and communication modules to reset, dropping network packets and triggering PROFINET watchdog faults. The boost feature eliminates this failure mode.

Q3: Can multiple QUINT-PS-3X400-500AC/24DC/30 units be paralleled for redundancy?Yes. Using the Phoenix Contact QUINT-DIODE/40AC/2X20DC or equivalent redundancy module, two QUINT PSUs can be connected in an N+1 configuration. If one unit fails, the second takes full load within microseconds, maintaining uninterrupted 24VDC supply to all connected automation and communication devices.

Q4: What warranty and pre-shipment testing does NANKMOS provide?Every QUINT-PS-3X400-500AC/24DC/30 unit ships with a 12-Month Warranty. Pre-shipment testing includes output voltage calibration, full-load current verification, boost function validation, and signal contact relay test. Units failing any parameter are quarantined and not dispatched. Contact [email protected] or +86 18359268345 for stock availability and lead time confirmation.
