Product Details

F3PU26-ON F3PU26-0N Product Description

The Yokogawa F3PU26-0N is a high-efficiency, energy-control power supply module engineered for the FA-M3 modular PLC platform. Designed to meet the rigorous demands of smart manufacturing environments, this module delivers stable, regulated DC power to FA-M3 CPU and I/O racks while actively minimizing idle power draw and thermal output. For facilities targeting measurable reductions in energy consumption, the F3PU26-0N serves as a foundational component in any power-aware automation architecture — from discrete assembly lines to continuous process plants.

In modern industrial facilities, unregulated power delivery is one of the most overlooked sources of energy waste. The F3PU26-0N addresses this directly by providing tightly regulated output voltage with low ripple, ensuring that downstream FA-M3 modules — including CPU units such as the F3SP71-4N, analog I/O modules, and communication interface cards — operate within their optimal power envelopes. This precision reduces thermal stress on components, extends mean time between failures (MTBF), and lowers the aggregate heat load that facility HVAC systems must manage.

The F3PU26-0N is most effective when deployed as part of a coordinated, power-aware control architecture. In a typical FA-M3-based production cell, the power supply module feeds regulated voltage to the F3SP71-4N sequence CPU, which executes ladder logic for machine sequencing and energy-state management. Paired with FA-M3 analog input modules monitoring real-time current draw from motor starters and actuators, the CPU can implement load-shedding routines that reduce peak demand charges — a critical lever in facilities billed on demand tariffs.

On the drive side, the F3PU26-0N-powered FA-M3 system communicates via MECHATROLINK-II or Modbus RTU to Yaskawa GA700 or Omron MX2 variable frequency drives, enabling speed-reference commands that match motor output to actual process load rather than running at fixed speed. This alone can reduce motor energy consumption by 20–40% in pump and fan applications. The FA-M3 I/O bus also supports connection to Yokogawa WT series power meters and third-party power monitoring modules via RS-485 or PROFIBUS-DP, feeding real-time kWh data back to the SCADA layer for energy dashboards and KPI tracking.

For servo-driven axes — such as those controlled by Yokogawa's own motion modules or compatible Mitsubishi MR-J4 servo amplifiers — the FA-M3 CPU coordinates position and torque commands while the F3PU26-0N ensures the control rack remains powered without voltage sag during high-inrush events at servo enable. On the HMI side, a Yokogawa-compatible touch panel or third-party Weintek HMI connected via Ethernet/IP can display live energy consumption trends, alarm states, and production throughput — giving operators a single-pane view of both process and energy performance.

The FA-M3 platform also supports F3LE01-5T Ethernet communication modules, enabling the F3PU26-0N-powered rack to participate in plant-wide OPC-UA data exchange with MES and ERP systems. This integration allows production schedulers to align high-energy operations with off-peak tariff windows, further reducing energy costs without sacrificing throughput. Temperature sensors and vibration monitors connected to FA-M3 analog or digital I/O modules feed condition data to the CPU, enabling predictive maintenance algorithms that prevent unplanned downtime — the single largest source of energy waste in discrete manufacturing.

Factories deploying the Yokogawa F3PU26-0N as the power backbone of their FA-M3 control racks gain a measurable advantage in production line energy optimization. Because the module's switching regulator maintains output stability across the full AC input range (100–240 VAC), it is immune to the voltage fluctuations common in heavy industrial environments where large motors and welding equipment share the same distribution panel. This immunity eliminates the micro-interruptions that force PLC CPUs into fault recovery cycles — cycles that not only waste energy but also disrupt production rhythm and reduce overall equipment effectiveness (OEE).

In multi-rack FA-M3 configurations, each rack requires its own power supply module. Specifying the F3PU26-0N across all racks standardizes the power architecture, simplifies spare-parts inventory, and ensures that maintenance teams can swap modules without reconfiguration. Standardization also enables centralized power monitoring: by logging the input current of each F3PU26-0N via clamp-on CT sensors connected to FA-M3 analog inputs, energy managers can identify racks with abnormally high draw — an early indicator of failing I/O modules or short-circuit conditions — before they escalate to production-stopping faults.

From a thermal management perspective, the F3PU26-0N's efficient conversion topology reduces the heat injected into the control panel enclosure. Lower panel temperatures extend the service life of all installed components — CPUs, communication modules, and I/O cards alike — and reduce the duty cycle of panel air conditioners, which are themselves significant energy consumers in large automation installations. In facilities with dozens of control panels, this compounding effect can represent thousands of kilowatt-hours saved annually.

All F3PU26-0N units supplied by NANKMOS are sourced from verified distribution channels, individually tested prior to shipment, and covered by a 12-Month Warranty. In-stock inventory ensures short lead times, supporting both planned capital projects and urgent replacement scenarios where production continuity is at stake.

Q1: What energy-saving benefit does the F3PU26-0N provide compared to older FA-M3 power supply modules? The F3PU26-0N uses a modern switching regulator topology that achieves higher conversion efficiency than earlier linear-regulated FA-M3 power supplies. This translates to less heat generated per watt delivered, lower panel cooling requirements, and reduced idle power draw when the FA-M3 rack is in standby or low-load states — directly contributing to facility energy KPIs.

Q2: Is the F3PU26-0N compatible with all FA-M3 rack configurations, including those using F3SP71-4N CPUs and F3LE01-5T Ethernet modules? Yes. The F3PU26-0N is designed to power standard FA-M3 base units and is compatible with the full range of FA-M3 CPU modules (including F3SP-series), I/O modules, and communication cards such as the F3LE01-5T Ethernet module. Always verify rack slot count and total module power budget against the F3PU26-0N's 26 W rated output before finalizing the configuration.

Q3: Can the F3PU26-0N be used as a direct replacement for other FA-M3 power supply variants, and what is the recommended testing procedure? The F3PU26-0N is a drop-in replacement for compatible FA-M3 power supply slots with matching output ratings. NANKMOS recommends a bench power-on test before installation: apply rated AC input, verify 5 VDC output under no-load, then install into the rack and confirm all module status LEDs indicate normal operation before returning the line to production. This procedure is included in NANKMOS pre-shipment testing and can be repeated on-site as part of commissioning.

Q4: What does the 12-Month Warranty cover, and how quickly can replacement stock be sourced? The 12-Month Warranty covers manufacturing defects and functional failures under normal operating conditions from the date of shipment. NANKMOS maintains in-stock inventory of the F3PU26-0N to support both warranty replacements and new procurement.
