Power-system comparison / mains and DC bus

TVD vs TVR Indramat Power Supplies

TVD and TVR are legacy Indramat power-supply families documented separately. Their role cannot be reduced to cabinet width or a similar DC-bus connection; mains equipment, power class, energy handling and connected drives must be reviewed.

Bottom line

What this comparison can establish

Treat TVD and TVR as different supply architectures. Identify the complete supply code and the entire mains-to-DC-bus path before planning replacement.

Side-by-side identity

What each product label must tell you

Role
Legacy power-supply family with edition-specific mains, DC-bus and auxiliary-component planning.
Verify
Full TVD code, line connection, continuous power, bus voltage, choke and braking components.
Do not assume
A TVD label match does not by itself confirm the connected line equipment or available braking capacity.
Role
Regenerative legacy supply family documented with its own system layout and mains requirements.
Verify
Full TVR code, mains components, regeneration path, DC bus, connected drives and installation edition.
Do not assume
Do not treat regenerative and bleeder-based energy handling as interchangeable.

Decision path

Turn the cabinet into a useful evidence set

01

What supply is physically installed?

Capture: Photograph the complete TVD or TVR label and cabinet position.

Then: Open the correct official applications manual edition.

02

How is energy handled?

Capture: Record braking resistor, bleeder, regeneration and line-return components.

Then: Keep the existing energy-handling architecture in the review.

03

What is connected to the bus?

Capture: List every drive module, motor load and auxiliary module on the DC bus.

Then: Check the supply as a system rather than a stand-alone box.

Official manufacturer records

Use the edition that matches the installed hardware.

Verified downloads open on the manufacturer’s site. Other references open a library entry with assistance options. Confirm the applicable edition, physical nameplate and machine documentation.

Common questions

Before you request a configured match

Can a TVD be replaced by a TVR?

That cannot be approved from family names. The mains, DC-bus, energy-handling, drive load and machine documentation must be reviewed.

Why photograph the whole cabinet?

Line components, braking or regeneration hardware and connected drives can determine what supply configuration is required.

Should a tripped supply be reset immediately?

Preserve the displayed and cabinet evidence first, then follow only qualified procedures and the applicable machine and manufacturer documentation.
