About TVR

Indramat TVR modules are regulated, regenerative power supplies for modular AC drive systems. The documented TVR3.1 design provides DC-bus and control voltages for connected Indramat main and servo drive modules and returns motor braking energy to the mains. Correct replacement selection requires the complete type code, incoming mains, connected drive load, DC-bus requirements, chokes, bleeder arrangement, grounding and cabinet conditions.

What to check before replacement or repair

Power modules are selected as part of a cabinet, not as isolated boxes. The incoming power, connected axes and braking cycle all affect the correct replacement.

Complete supply type code and power designation
Mains voltage, transformer and line components
Connected drive modules and total cabinet load
Braking, bleeder, regeneration, fan and cooling arrangement

Record the cabinet fault, line conditions and connected load before removing the supply. Photos of adjacent modules and wiring give Litco the system context needed for evaluation.

Helpful photos: the nameplate, complete unit, connections and shaft or cabinet context.
