Beckhoff AX8640-0000-0000 Capacitor Module

Beckhoff AX8640-0000-0000 Capacitor Module

Product Description

The Beckhoff AX8640-0000-0000 is an AX8000 Multi-Axis Servo System power supply module. It converts three-phase AC mains power into the DC link voltage required by AX8000 axis modules and option modules. It includes an integrated mains filter and supports energy management for high-performance servo applications. Note: AX8640 is a power supply module, not a capacitor module; the AX8000 capacitor module is AX8810.
