Schneider VX4DCPD45N4 DC Bus Power Board

Feature & Principle

It is Schneider Altivar series inverter dedicated DC bus power board. It adopts SCR+IGBT hybrid power topology, completes rectification and DC bus energy buffering, provides stable DC voltage for the post-stage inversion unit. It integrates power semiconductor devices, absorption circuit and temperature detection, with built-in overvoltage, overcurrent and overtemperature protection. This model is discontinued, mainly used for maintenance and replacement of old 45kW ATV series frequency converters.
