Product Details

2866802 Product Description

The Phoenix Contact 2866802 QUINT-PS 3AC/24VDC/40A is an advanced energy-control industrial power supply engineered for demanding automation environments where power quality, load stability, and energy efficiency are non-negotiable. Designed to deliver a regulated 24 VDC output at up to 40 A from a three-phase AC input, this unit integrates seamlessly into modern production lines, providing the stable, clean power backbone that drives consistent machine performance, reduces thermal stress, and supports intelligent energy management across the entire plant floor.

Built on Phoenix Contact's proven QUINT-PS platform, the 2866802 incorporates active power factor correction and high-conversion efficiency to minimize reactive power losses and reduce overall energy draw — directly contributing to lower operating costs and a reduced carbon footprint for energy-intensive manufacturing facilities. Its wide input voltage tolerance and robust thermal design ensure reliable operation across variable grid conditions, making it equally suited for retrofit installations and greenfield smart factory deployments.

In a fully integrated smart production line, the Phoenix Contact 2866802 QUINT-PS serves as the central power distribution node, feeding stable 24 VDC to a wide array of automation components. Siemens SIMATIC S7-1500 PLCs and Mitsubishi MELSEC iQ-R series controllers rely on clean, regulated DC power to execute deterministic control cycles without voltage-induced jitter — a critical requirement in high-speed assembly and precision machining applications.

Variable frequency drives (VFDs) such as the ABB ACS880 and Siemens SINAMICS G120 manage motor speed and torque across conveyor systems, pumps, and compressors. While these drives draw from the AC mains, their control electronics, fieldbus interfaces, and cooling fans are powered from the 24 VDC rail supplied by the 2866802. Stable auxiliary power ensures that drive parameter sets are retained, communication links remain active during transient load events, and fault diagnostics are continuously available to the SCADA layer.

Phoenix Contact QUINT-PS units are frequently deployed alongside the QUINT-DIODE redundancy modules and QUINT-UPS uninterruptible power supply modules to create fault-tolerant power architectures. In lines where servo drives — such as the Panasonic MINAS A6 or Yaskawa Σ-7 series — demand instantaneous current peaks during acceleration, the QUINT-PS 2866802's dynamic boost function delivers up to 200% rated current for short durations, preventing nuisance tripping and maintaining production rhythm.

On the sensing and feedback layer, IO-Link masters, Turck Banner inductive proximity sensors, and Balluff linear position transducers all draw from the 24 VDC bus. Consistent supply voltage directly impacts sensor switching accuracy and signal integrity, reducing false triggers that can disrupt automated quality inspection stations. Phoenix Contact's AXIOLINE F and INLINE I/O modules distribute this power across distributed I/O nodes, while PROFINET and EtherNet/IP communication modules maintain real-time data exchange with the plant's MES and SCADA systems.

For energy monitoring, the 2866802 is commonly paired with Phoenix Contact EEM-MA770 power measurement modules or third-party power analyzers connected via Modbus RTU or PROFIBUS DP. These instruments capture real-time consumption data at the panel level, feeding energy dashboards that identify idle-state losses, peak demand events, and opportunities for load shedding during off-peak production windows.

Energy waste in industrial facilities rarely originates from a single source — it accumulates across hundreds of small inefficiencies: oversized power supplies running at partial load, poorly matched motor drives, and control panels drawing standby current around the clock. The Phoenix Contact 2866802 QUINT-PS addresses the power supply layer of this challenge with a combination of high conversion efficiency, active power factor correction, and intelligent load management features that reduce both active and reactive energy consumption.

At full 40 A load, the QUINT-PS 2866802 operates at ≥ 95% efficiency, meaning less than 5% of input energy is lost as heat. This directly reduces the thermal load on the control cabinet, lowering the duty cycle of cabinet cooling fans and air conditioners — secondary energy consumers that are often overlooked in energy audits. In facilities with dozens of control panels, this cascading efficiency gain can represent a measurable reduction in annual electricity costs.

The unit's static output voltage regulation (±1%) ensures that downstream PLCs, HMIs, and I/O modules operate within their optimal voltage windows, preventing the micro-resets and communication errors that cause unplanned line stoppages. Unplanned downtime is one of the most expensive forms of energy waste — idle conveyors, pressurized pneumatic systems, and heated process chambers all consume energy while producing zero output. By maintaining power quality, the 2866802 contributes directly to OEE (Overall Equipment Effectiveness) improvement targets.

For predictive maintenance programs, the QUINT-PS 2866802's integrated signaling output provides early warning of output voltage deviation or overload conditions, allowing maintenance teams to schedule interventions during planned downtime windows rather than reacting to failures. This proactive approach reduces mean time to repair (MTTR) and extends the service life of connected automation equipment.

All units are shipped from verified stock, subject to pre-shipment functional testing, and covered by a 12-Month Warranty from the date of dispatch. Inventory availability is maintained to support both urgent replacement orders and scheduled project procurement timelines.

Q1: What energy savings can I expect by deploying the Phoenix Contact 2866802 QUINT-PS in my control panel? The 2866802 achieves ≥ 95% conversion efficiency with active PFC (> 0.99), significantly reducing reactive power losses compared to conventional power supplies. In multi-panel installations, this translates to lower electricity bills, reduced cooling requirements, and a smaller carbon footprint. Exact savings depend on load profile and operating hours.

Q2: Is the 2866802 compatible with my existing PLC and fieldbus infrastructure? Yes. The QUINT-PS 2866802 provides standard 24 VDC output compatible with all major PLC platforms (Siemens, Mitsubishi, Omron, Rockwell) and supports distributed I/O, HMI panels, communication gateways, and fieldbus nodes operating on PROFINET, EtherNet/IP, Modbus, or PROFIBUS. No special interface is required — it integrates directly into your existing 24 VDC distribution architecture.

Q3: Can this unit replace an aging or failed power supply in an existing QUINT-PS installation? The 2866802 is a direct form-fit-function replacement for equivalent QUINT-PS 3AC/24VDC/40A units. DIN rail mounting dimensions and terminal layouts are consistent with the QUINT-PS platform standard. Always verify input voltage range and output current rating against your panel documentation before installation. Our technical team can assist with cross-reference validation upon request.

Q4: What does the 12-Month Warranty cover, and how is pre-shipment testing conducted? Every Phoenix Contact 2866802 unit is functionally tested prior to shipment to verify output voltage regulation, overload response, and signaling output operation. The 12-Month Warranty covers manufacturing defects and functional failures under normal operating conditions from the date of shipment. Warranty claims are processed directly — contact [email protected] with your order reference and fault description to initiate a return or replacement.
