INDRAMAT TVM 2.2-050-220/300-W1-220/380 Power Supply Module

Overview

The INDRAMAT TVM 2.2-050-220/300-W1-220/380 is a regulated DC bus power supply module from the Indramat TVM series, designed to supply 300 V DC bus power for Indramat TDM series servo drive controllers. The INDRAMAT TVM 2.2-050-220/300-W1-220/380 accepts three-phase 220 V AC mains input and supports auxiliary control voltage options of 220 V or 380 V AC, with a rated output current of 50 A. This power module handles rectification, bus voltage stabilization and regenerative energy absorption for multi-axis servo systems, and is widely stocked as spare unit for legacy machine tools, printing machinery and metal forming automation equipment. The INDRAMAT TVM 2.2-050-220/300-W1-220/380 is a discontinued legacy unit originally developed by Indramat, now part of Bosch Rexroth product portfolio.

Features

The INDRAMAT TVM 2.2-050-220/300-W1-220/380 adopts controlled rectifier topology and built-in blower cooling for continuous high-load operation. It provides stable 300 V DC bus output and can absorb regenerative energy fed back from servo motors during deceleration. The INDRAMAT TVM 2.2-050-220/300-W1-220/380 integrates comprehensive protection including overvoltage, undervoltage, overcurrent, overtemperature and short-circuit protection. It supports fault status indication via front panel LEDs and fault reset button, and communicates with matched TDM servo controllers through internal control signal wiring. The INDRAMAT TVM 2.2-050-220/300-W1-220/380 is designed for rack mounting inside the control cabinet, and follows the original pin definition for direct replacement of the same TVM 2.2 series power supply.

Principle

The INDRAMAT TVM 2.2-050-220/300-W1-220/380 receives three-phase AC power and converts it into smoothed 300 V DC bus voltage through rectifier and capacitor bank. The DC bus is shared by multiple TDM servo controllers to power the servo power stages. When servos decelerate, regenerative energy returns to the DC bus and the power supply circuit manages bus voltage to avoid overvoltage trip. The INDRAMAT TVM 2.2-050-220/300-W1-220/380 continuously monitors bus voltage, output current and internal temperature, and locks output and sends fault signal when abnormal conditions occur.

Applications

The INDRAMAT TVM 2.2-050-220/300-W1-220/380 serves as the central power supply for multi-axis Indramat TDM servo systems in CNC machine tools, packaging machines and hydraulic press automation lines. It supplies stable DC bus power for synchronous and asynchronous servo drives. The INDRAMAT TVM 2.2-050-220/300-W1-220/380 applies to spare stock and emergency repair of legacy Indramat motion control assemblies. It also supports servo cabinet renovation and bus power loop debugging projects.
