PFMA20LCYUNV176S891 EATON Power Board

Product  Description：

An EATON power board integrates various components like circuit breakers, surge protectors, power conditioning circuits, and sometimes communication interfaces onto a single assembly. Their function is to take incoming power, distribute it safely to multiple loads or internal components, provide essential protection against overcurrents and surges, and often monitor power quality and consumption. They are designed for high efficiency and robustness to ensure the uptime of critical systems.

Product Parameters (Typical)

Parameters are highly dependent on the specific EATON product the board is contained within (e.g., a UPS Power Board versus a Switchgear Control Board).

• Input Voltage/Current: The nominal input voltage (e.g., 120V AC, 208V AC, 480V AC, or DC voltages) and the maximum current rating the board can handle (e.g., 20A, 100A).

• Output Voltage/Current: The number and rating of output circuits (e.g., 4 x 15A output channels, 12V DC output).

• Power Capacity: The total power (kVA or kW) the board is rated to manage.

• Protection Features:

  • Circuit Breaker/Fuse Ratings: Specific trip ratings of integrated protection devices.

  • Surge Protection: Clamping voltage and joule rating for transient suppression.

• Switching Frequency: Applicable for boards in UPS inverters/converters (e.g., 20 kHz to 60 kHz).

• Communication Ports: Availability of ports for monitoring (e.g., RS-232, USB, Ethernet via dedicated card slot).

• Efficiency: Power conversion efficiency (e.g., up to 98% for power management boards).

• Form Factor/Dimensions: Physical size tailored to fit the specific EATON enclosure.

• Operating Temperature: The industrial or commercial temperature range (e.g., 0°C to 50°C).

Product Advantages

• Superior Reliability and Uptime: Designed with high-quality components and robust thermal management to ensure continuous, uninterrupted power flow to critical loads.

• Integrated Protection: Provides consolidated and effective protection against common power disturbances such as overcurrents, short circuits, and voltage surges.

• Optimized Efficiency: Often incorporates highly efficient power conversion or distribution circuitry, reducing energy loss and operating costs.

• Ease of Maintenance: Modular design (when applicable) facilitates quick replacement, minimizing downtime during service.

• Regulatory Compliance: Designed and manufactured to meet global safety and performance standards (e.g., UL, CE, IEC).

• Advanced Monitoring: Enables precise power consumption measurement and remote diagnostics when paired with EATON's monitoring hardware/software.

Precautions

• Load Rating: Never exceed the maximum voltage and current ratings specified for the board's input and output circuits to prevent overheating and failure.

• Grounding: Ensure the board and the host system are properly earthed/grounded according to all electrical codes to ensure safety and effective surge protection.

• Installation Environment: Install and operate within the specified temperature, humidity, and ventilation limits. Excessive heat is the primary cause of electronic power board failure.

• ESD Handling: Always observe proper Electrostatic Discharge (ESD) handling procedures when installing, removing, or servicing the board to prevent damage to sensitive components.

• Safety Procedures: De-energize and lock out all upstream power sources before performing any installation, wiring, or maintenance work on the board.

Product Applications

EATON power boards are foundational components used across various industries in systems requiring high-reliability power management.

• Data Centers and IT: Integrated into EATON UPS (Uninterruptible Power Supply) systems, PDUs, and rack enclosures to distribute and protect power for servers and networking equipment.

• Industrial Automation: Used within Motor Control Centers (MCCs), industrial control panels, and automation switchgear for power distribution and circuit protection for machinery.

• Commercial Buildings: Incorporated into lighting control systems and building management power distribution panels.

• Healthcare Facilities: Essential within medical-grade UPS and isolation power systems to ensure life-support and monitoring equipment have clean, continuous power.

• Telecommunications: Used in power plants and distribution frameworks for reliable DC or AC power supply to communication equipment.
