JZNC-TU04 YASKAWA Power Board

Product  Description：

Yaskawa Power Boards are high-performance power distribution and conversion units primarily used in AC drives (VFDs), servo amplifiers, and specialized machine controllers. These boards act as the power stage of the equipment, housing the critical components that convert incoming electrical energy into the precise regulated power required to drive industrial motors and internal control electronics.

Product Parameters

The technical characteristics of Yaskawa Power Boards are defined by their thermal management and high-voltage handling capabilities:

• Input Voltage Support: Designed for standard industrial ranges including 200V-240V AC (single or three-phase) and 380V-480V AC (three-phase).

• DC Bus Management: Capable of rectifying AC input into a stable DC bus voltage, often rated for 300V DC or 600V DC depending on the model.

• Current Capacity: Varies significantly by model, with power boards for small servo drives handling 5A to 15A, while large inverter boards manage 100A or more.

• Output Frequency Range: Supports high-speed switching frequencies typically between 2 kHz and 16 kHz to minimize motor noise and heat.

• Component Integration: Features integrated IGBT (Insulated Gate Bipolar Transistor) gate drive circuits and current sensing transformers.

• Auxiliary Power Outputs: Provides secondary low-voltage outputs (such as 5V, 15V, or 24V DC) to power the control unit and cooling fans.

Product Advantages

Yaskawa Power Boards are recognized for their robust design and energy efficiency:

• High Power Density: Utilizes advanced multi-layer PCB designs and high-efficiency semiconductors to maximize power output while maintaining a compact physical footprint.

• Optimized Thermal Dissipation: Engineered with heavy copper traces and direct thermal coupling to heatsinks, ensuring the board stays within safe temperature limits during continuous operation.

• Advanced Protection Circuits: Features onboard hardware-level protection for overcurrent, overvoltage, and short-circuit conditions, reacting faster than software-based safety loops.

• Low Electromagnetic Interference: Designed with strategic component placement and grounding planes to minimize electrical noise, ensuring compliance with global EMC standards.

• Long Service Life: Built with high-quality electrolytic capacitors and components rated for high-temperature industrial environments, reducing the risk of premature board failure.

Product Applications

These boards are the energy backbone for a variety of Yaskawa’s high-precision equipment:

• Sigma-7 Servo Amplifiers: Delivering the rapid current pulses necessary for the high-dynamic response of Yaskawa servo motors.

• GA700 and A1000 Inverters: Managing the high-power conversion required for heavy-duty industrial motor control in cranes and fans.

• Robotic Controllers: Distributing power to multiple axes in Yaskawa Motoman robots, ensuring coordinated and efficient movement.

• Regenerative Power Units: Facilitating the return of braking energy from motors back into the power grid, enhancing system-wide energy savings.

• Elevator Drive Systems: Providing the smooth and reliable power delivery required for passenger comfort and safety in vertical transport.

Important Precautions

Handling and maintaining power boards require strict adherence to safety protocols due to the presence of high-voltage energy:

• Discharge Time: Power boards contain large capacitors that store lethal energy. After disconnecting power, wait at least 15 minutes and verify the DC bus voltage is zero before touching any components.

• ESD Sensitivity: While built for high power, the control traces on these boards are sensitive to static. Always use an ESD-safe wrist strap when handling the board.

• Proper Cooling: Ensure the thermal grease is applied correctly between the power modules and the heatsink during replacement. Inadequate thermal contact will lead to immediate board failure.

• Fastening Torque: When connecting power cables to terminal blocks, use a torque wrench to meet the manufacturer's exact specifications. Loose connections create high resistance and fire hazards.

• Environmental Protection: Prevent conductive dust, moisture, or oil mist from entering the cabinet. Contamination on the power board can cause electrical tracking and catastrophic short circuits.
