Applications and Compatibility

The Schneider VX5A1HD45N4 is listed by industrial spare parts suppliers as a 45kW power / driver board for selected Altivar 61 and Altivar 71 drive applications.

Relevant 45kW drive references include:

• ATV61HD45N4
• ATV71HD45N4

Important Compatibility Checks:

Schneider’s official spare parts documentation identifies a specific replacement arrangement for the ATV61HD45N4 and ATV71HD45N4 models. The listed service kit VX5IM2200M1271 includes a power board and power IGBT modules.

Before ordering, verify:

• Confirm that the original board carries the exact part number VX5A1HD45N4.
• Check the complete ATV61 or ATV71 drive model.
• Verify the N4 or M3X hardware version.
• Check the drive serial number and IGBT configuration.
• Compare the board revision and identification markings.
• Check connector positions and pin configuration.
• Confirm whether the original replacement requires a board-only part or a complete power board and IGBT kit.

Important: Do not confuse VX5A1HD45N4 with VX5A1HD45M3X. These are different board references associated with different drive configurations.

How to Identify the Correct Replacement Board

When replacing a power / driver board, carefully compare the existing board with the replacement unit.

Check the following details:

• Part number printed on the original PCB.
• Board revision and identification labels.
• Connector positions and pin configuration.
• Power electronic component layout.
• Mounting positions and electrical connections.
• Complete ATV61 / ATV71 drive nameplate.
• Drive serial number and IGBT configuration.

If you are unsure about compatibility, send us clear photos of the existing board and the drive nameplate before ordering.

When Should the Power / Driver Board Be Replaced?

A power / driver board may require inspection when the inverter experiences abnormal power-stage operation or related electronic faults.

Before replacing the board:

• Inspect the board for visible damage or burnt components.
• Check connectors and electrical connections.
• Inspect the associated IGBT power modules.
• Review the drive fault history and diagnostic results.
• Verify the correct board number and hardware version.

A drive fault does not automatically mean the power / driver board is defective. Other power-stage components and connections should also be inspected by qualified personnel.
