Specifications

Compatibility Note

• Compatible with Schneider Altivar ATV610, ATV630, and ATV930 series drives
• Specifically for 110KW, 132KW, and 160KW power ratings
• Alternative part numbers: NHA50709_00, NHA50710_01, VX4PPC16N4, VX4PPC13N4, VX4PPC11N4 – verify original board marking
• CRITICAL: Nameplate photo required – different power ratings and drive versions may use different board variants
• If mismatched: Incorrect board selection may result in drive failing to power up, reporting “DC Bus Fault,” or experiencing IGBT drive errors
• This board is not a generic replacement – EMI filter impedance and pre-charge timing are critical for system stability
• Verify drive model, power rating, and original board marking before ordering
• Send drive nameplate photo for accurate matching

Quality Assurance

• Original pulled from working drive; tested functional with no repair history
• Actual photos sent before shipping
• Test video available upon request
• ESD anti-static packaging
