Description

Bosch Rexroth Indramat TVM2.4-050-220/300-W1, TVM Series Power Supply / Servo Power Supply Module

Core Product Overview

TVM2.4-050-220/300-W1 is an Indramat TVM series regulated power supply unit for the Rexroth Indramat servo system. It rectifies three-phase AC input and supplies stable DC bus voltage to the matching servo drive axes modules. It has built-in braking chopper circuit for regenerative energy handling, fault diagnostics, overvoltage, overcurrent and overtemperature protection. It pairs with Indramat DKC / DDS axis controllers and 2AD series asynchronous servo motors (such as 2AD160B-B350R2-BS03-D2N1). It is a power supply unit, not a DCS controller or I/O card.

Professional Quality Control & Testing Standard Operating Procedures

All surplus and refurbished .4-050-220/300-W1 modules follow this inspection workflow:

1. Visual Inspection: Check cabinet housing, cooling fan, power terminals, control connector, PCB, capacitors and label marking.
2. Megger & Insulation Test: Verify insulation between power circuits and ground.
3. Input Rectifier Test: Measure diode bridge health, no shorted power devices.
4. No-Load Power-Up Test: Apply 3-phase 220V AC input, confirm DC bus rises to 300V DC, no fault alarm.
5. Braking Chopper Function Test: Validate chopper activation for regenerative energy dumping.
6. Fault Signal Test: Check fault relay and status LED signals.
7. Load Test: Connect resistive load, test output stability under rated current, monitor temperature rise.
8. Final Cleaning & Packaging: Replace aging fan if needed, torque terminals, ESD protection, attach test certificate.

New / Refurbished Module Installation Guidelines

1. Pre-Installation Safety: Execute LOTO procedure, lock three-phase input power, wait for DC bus discharge, confirm zero residual voltage.
2. Cabinet Check: Confirm servo cabinet ventilation, no blocked air filters, proper protective earth connection.
3. Mechanical Mounting: Slide module into Indramat rack, secure mounting screws.
4. Wiring: Terminate 3-phase AC input, DC bus output, control enable and fault wiring; separate power cables from encoder signal cables.
5. Interlock Configuration: Wire fault relay into machine emergency stop circuit.
6. Offline Functional Test: Power up without axis modules, verify DC bus voltage and fault status.
7. Commissioning & Acceptance: Pair with axis modules and servo motor, test acceleration / deceleration and regenerative braking, archive test records.

Application Scenarios & Product Features

Typical Application Scenarios

• Indramat multi-axis servo cabinets for machine tools
• Automation lines, metal forming, packaging machinery with 2AD asynchronous servo motors
• Spare replacement for legacy TVM power supply based Indramat motion control systems

Core Product Features

• Converts 3-phase 220VAC to regulated 300V DC bus for servo axes
• Rated 50A continuous DC output for multi-axis configuration
• Integrated braking chopper to absorb motor regenerative energy
• Comprehensive hardware protection against overload and fault conditions
• Rack-mounted form factor compatible with classic Indramat servo racks
• Must work together with Indramat axis controllers; cannot drive motors directly
• Obsolete legacy unit; capacitor ageing is a common risk on old stock

Frequently Asked Questions (FAQ)

Q1: Can this module work as a standalone power supply for general loads? A1: Not recommended. It is designed specifically as a servo bus supply for Indramat axis modules with dedicated enable and fault logic.

Q2: What does 220/300 mean in the part number? A2: 220 = three-phase AC input rating; 300 = nominal DC bus output voltage.

A3: Mechanically compatible, higher current rating, can be used as an upgrade, but cabinet load and fusing must be reviewed.

Q4: What are common failure modes? A4: Electrolytic capacitor bulge/dry-out, cooling fan failure, IGBT/rectifier short, braking resistor circuit failure, terminal corrosion.

Q5: Is this a DCS or SIS module? A5: No. It is a motion control servo power supply from Rexroth Indramat, unrelated to Honeywell / Yokogawa process control systems.
