QPHW2100  EATON Power Board

Product  Description：

The EATON Power Board, in the context of automation components, is a specialized circuit board or module that functions as the internal power supply unit for the host industrial controller or device. Its primary role is to convert the incoming line voltage (AC or DC) into the stable, regulated DC voltages required by the internal electronics, such as the CPU, memory, and I/O circuits (typically $+5 \text{ V}_{\text{DC}}$, $+12 \text{ V}_{\text{DC}}$, or $+24 \text{ V}_{\text{DC}}$). It incorporates features like voltage regulation, noise filtering, overcurrent protection, and short-circuit protection to ensure the clean and reliable operation of sensitive digital components. This board is essential for the system's overall integrity and often includes diagnostic LEDs to indicate power status and fault conditions.

Product Parameters

The specific parameters for an EATON Power Board or Supply Module are determined by the host system and application:

• Input Voltage Range: Specifies the acceptable operating range, such as $100 \text{ V}_{\text{AC}}$ to $240 \text{ V}_{\text{AC}}$ (Universal AC) or $20 \text{ V}_{\text{DC}}$ to $30 \text{ V}_{\text{DC}}$ (DC powered systems).

• Output Voltage(s) and Current: Defines the regulated DC voltages supplied to the internal components (e.g., $+5 \text{ V}_{\text{DC}}$ at $2 \text{ A}$, $+24 \text{ V}_{\text{DC}}$ at $1.5 \text{ A}$).

• Efficiency: The ratio of output power to input power, typically expressed as a percentage (e.g., $\ge 90\%$). Higher efficiency means less heat generation.

• Power Rating: The maximum total output power the board can deliver, measured in Watts (W).

• Ripple and Noise: The degree of unwanted AC components remaining in the DC output, usually specified in millivolts peak-to-peak ($\text{mV}_{\text{p-p}}$). Lower values are better for digital circuits.

• Hold-Up Time: The duration the output power can be maintained after the input power is lost, typically in milliseconds (ms).

Product Advantages

EATON Power Boards are engineered with several advantages crucial for industrial applications:

• High Reliability: Designed for continuous operation in harsh environments, these boards feature robust components and thermal management to ensure long service life and minimal failure rates.

• Clean Power Output: The advanced filtering and regulation circuitry provides extremely stable and low-noise DC power, which is critical for the accurate operation of microprocessors and analog I/O modules.

• Comprehensive Protection: Built-in safeguards, including over-voltage, over-current, and thermal shutdown protection, shield the entire automation system from damage due to electrical disturbances.

• Wide Input Tolerance: They are designed to tolerate significant voltage fluctuations and brownouts on the main power line, maintaining stable output power for the control system.

Important Considerations (Precautions)

Proper installation and maintenance of the Power Board are essential for system safety and longevity:

• Input Wiring: Ensure the input wiring is correctly terminated and sized according to the board's specifications to prevent fire hazards or voltage drops.

• Thermal Management: Adequate ventilation and clearance must be maintained around the host device to allow for proper heat dissipation, as power boards generate significant heat.

• Load Calculation: The total current draw of all connected I/O modules and system components must not exceed the maximum power rating of the Power Board. Overloading will lead to overheating and potential failure.

• Grounding: The system and the power board's ground terminals must be properly and securely connected to earth ground to ensure effective noise suppression and safety protection.

Product Applications

The EATON Power Board is fundamentally applied wherever reliable electrical conversion and distribution are needed within industrial electronics:

• Industrial Control Panels: Serving as the primary power supply for PLCs, remote I/O racks, and industrial PCs in control cabinets.

• Variable Frequency Drives (VFDs): Integrated into VFDs to supply isolated, stable power to the internal control logic and communication circuits.

• Human Machine Interfaces (HMIs): Used in industrial touch panels and displays to convert the main control voltage into the required DC power for the display and computing components.

• Distributed I/O Systems: Powering field-mounted I/O blocks where reliability and robust voltage regulation are necessary to communicate with the main controller over industrial networks.
