Applications and Compatibility

The Schneider PN072126P2 is listed for selected high-power Altivar 61 and Altivar 71 inverter applications.

Available supplier references associate this board with:

• ATV61 – selected high-power drive configurations.
• ATV71 – selected high-power drive configurations.
• 315kW and 400kW application references.

One Schneider ATV71 model, ATV71HC31N4, is rated at 315kW / 500HP with a 380–480V supply. This does not mean that the board is suitable for every 315kW or 500HP drive.

Important Compatibility Checks:

Before ordering, verify:

• Confirm that the original board carries the exact part number PN072126P2.
• Check the complete ATV61 / ATV71 drive model.
• Verify the drive power rating and voltage class.
• Compare the original board revision and identification markings.
• Check connector positions and pin configuration.
• Verify the IGBT manufacturer and power configuration.
• Confirm whether the original board requires an additional F suffix.

Schneider Electric specifies that ATV61 and ATV71 power boards are not universally interchangeable, even when they share the same frame size. Components can differ according to horsepower and voltage rating.

Important IGBT Version Check:

Some ATV61 drives use Fuji IGBTs instead of standard Mitsubishi IGBTs.

According to Schneider Electric, when the eighth digit of the drive serial number is 2, the drive uses Fuji IGBTs. The corresponding replacement power board, IGBT, measuring board and gate driver board may require an additional F suffix.

Always verify the original board version and drive serial number before ordering.

How to Identify the Correct Replacement Board

When replacing a high-power inverter 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.
• Electronic component layout.
• Related IGBT configuration.
• Mounting positions and electrical connections.
• Complete drive model and serial number.

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

When Should the High-Power Driver Board Be Replaced?

A high-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 driver board is defective. Other power-stage components and electrical connections should also be inspected by qualified personnel.

Frequently Asked Questions

What is the PN072126P2 used for?

The PN072126P2 is listed as a high-power inverter drive board for selected Schneider Altivar 61 and Altivar 71 applications.

Which power ratings are associated with PN072126P2?

Supplier listings associate this board with 315kW and 400kW high-power drive applications. Confirm the exact drive model before ordering.

Does 500HP mean the drive is rated at 500kW?

No. Horsepower (HP) and kilowatts (kW) are different units. For example, the Schneider ATV71HC31N4 is rated at 315kW / 500HP.

Are PN072126P2, VX5A1203 and PN072129P3 interchangeable?

These references appear together in some supplier listings. However, direct interchangeability has not been confirmed. Compare the original board identification and hardware configuration before replacement.

Is this board tested?

This listing is for tested stock. Please request available inspection and functional testing details before purchase.
