The Lenze 9217 Supply Module is a digital power conditioning unit engineered for the 9200 Controller Series, delivering stable DC voltage and current to servo drives and industrial automation systems. This supply module accepts 400 V or 480 V three-phase input and outputs 540 V or 620 V DC at 46 A, supporting four-quadrant operation across any speed and torque direction. Control is managed by a 16-bit microcontroller paired with three ASICs executing field-oriented vector current control. The module employs IGBT inverter technology with user-selectable chopper frequencies—8 kHz for low-noise operation or 16 kHz for silent mode. Operating at 50/60 Hz mains frequency, the 9217 integrates into central supply configurations where multiple servo modules connect to a shared DC-bus. Weighing 13.0 kg, it occupies compact dimensions suited to distributed drive systems. When system power demand exceeds the 9217’s rating, additional supply modules can be installed and DC-bus sets subdivided for load sharing, enabling scalable power architecture without replacing the entire supply infrastructure.
