Schneider VX4DCPD30N Inverter DC Bus Power Board Inquiry Item

Details

This Schneider VX4DCPD30N is a dedicated DC bus IGBT power drive board for Schneider Altivar ATV series inverters with 30kW power grade, 400V voltage class. It integrates IGBT power modules, rectifier circuit, drive circuit and DC bus capacitor loop, undertakes AC-DC rectification and DC-AC inversion energy conversion of the frequency converter. It receives pulse drive signals from the control board to realize three-phase variable voltage variable frequency output for driving asynchronous motors. This is a discontinued spare part, mainly used for maintenance and replacement of old ATV series industrial inverters in water treatment, metallurgy and petrochemical control cabinets.
