What TVR3.1 identifies
The Indramat application manual documents TVR3.1 as a regulated power supply for a modular AC drive system. It supplies DC-bus and control voltages to connected main and servo drive modules and returns motor braking energy to the mains. Direct-mains use, transformer use, grounding, commutation choke, connected load and accessory selection remain system-engineering decisions.
Ratings, connections, feedback, braking and mechanical options vary by complete type code. Send Litco Automation a clear nameplate photo so the exact configuration and compatible replacement can be confirmed.

Series questions
TVR3.1 questions
Before Litco pulls a unit
Is TVR3.1 enough information to order a replacement?+
No. TVR3.1 identifies the series group, but the complete type code still carries the power, mains, braking, cooling, DC-bus and cabinet options that determine compatibility.
Which TVR3.1 fields should I compare first?+
Start with complete tvr series, version and power code; three-phase mains voltage and grounding arrangement; connected drive modules and continuous mechanical load. Then preserve the remaining suffix, material number, revision and every installed option or firmware label.
Where is TVR3.1 equipment commonly used?+
TVR3.1 is documented for regenerative modular ac drive systems, legacy main and servo drive cabinets, machine-tool drive systems, multi-axis production machinery. The installed machine, axis and connected equipment still control the final replacement decision.
Can Litco evaluate a failed TVR3.1 unit?+
Yes. Litco can discuss replacement, repair and exchange paths after reviewing the complete code, application and failure information.
