The **Bosch Rexroth Indramat RAC 3.5-150-460-A0I-W1-220V** from the **RAC Spindle Drive Controllers** series is an advanced **AC Main Spindle Drive Controller** engineered for CNC machine tool applications. It connects to a three-phase network at **3 x AC 400 V, 50 Hz ±15% or 3 x AC 460 V**, delivers a continuous output of **35 kW** (peak **55 kW**) with a rated current of **150 A** and control electronics powered at **AC 230 V/50-60 Hz**. Featuring an internal blower, **built-in fan** cooling, **IP10** protection and an ambient range of **+5°C to +45°C**, it supports **incremental encoder output**, SERCOS interfaces and an **X4, 9-pole** interface terminal. The unit retains settings via an AS programming module for rapid commissioning and allows flexible cooling air routing, simplifying installation and maintenance.
