Name: Inverter PCB Assembly
Part Number: P29545
Includes:

• Inverter PCB (for power modulation and compressor control)

• Inverter Fin Assy (for heat dissipation and thermal protection)

Function:
This inverter PCB assembly is designed to regulate and control the inverter stage of Hitachi heat pump systems, ensuring precise compressor modulation and energy-efficient operation. The integrated fin assembly enhances thermal performance by effectively dissipating heat from the high-power electronic components.

✅ Compatibility

• Compatible with multiple Hitachi heat pump models, particularly those using inverter-driven compressors (typically seen in residential and light-commercial units such as Yutaki and other VRF or split-type systems).

To determine exact compatibility, reference the unit’s model number, technical documentation, or cross-reference parts list for your specific Hitachi system.

🔧 Key Functional Features

🎛️ Inverter Control

• Manages the modulation of the compressor motor to provide variable speed control

• Supports soft-start functionality to reduce electrical stress

• Works in tandem with the main controller PCB to match heating/cooling output to demand

🌡️ Thermal Management

• The Inverter Fin Assy acts as a heat sink to:

  • Maintain ideal component temperatures

  • Prevent thermal shutdowns

  • Extend board longevity

⚡ Efficiency & Reliability

• Improves SCOP (Seasonal Coefficient of Performance)

• Reduces power cycling and energy loss

• Ensures stable performance during fluctuating loads or environmental conditions

🛠️ Installation & Maintenance

📦 Features:

• Pre-mounted on thermal fin assembly for fast installation

• Plug-and-play with correct connectors (subject to model compatibility)

• May require firmware recognition or synchronization with main controller on startup
