Bronson TT 3000 — Isolation Transformer 3000W

230V isolation transformer with galvanic isolation for workshop, stage, marine, and IT. 3000W max, 2400W continuous, toroidal core.

3000W max / 2400W continuous — multiple devices

The TT 3000 delivers 2400W continuous load and up to 3000W short-term. It runs several professional devices at once on an isolated circuit. An overheat cutoff guards continuous operation.

230V ↔ 230V — galvanic isolation, PE screen

As a toroidal transformer the TT 3000 isolates the output galvanically from the 230V supply (1:1, 98%). An electrostatic screen on PE keeps line interference off the floating output.

Terminal input + Schuko/UK, no IEC

The TT 3000 is fed through a screw terminal (no IEC plug). The output provides Schuko Type F, UK Type G, and a screw terminal — for fixed installation and mobile connection.

Frequently asked questions

Can I run the TT 3000 behind a portable generator with a split-phase output?

Yes. The TT 3000 takes the 240V between the two line conductors (L1–L2) as its input and delivers an isolated 230V circuit from it.

The floating secondary can be referenced to PE through a defined neutral (N). That turns a split-phase source into a clean 230V L-N output for European equipment.

Can the TT 3000 be installed behind an inverter with its own earth rod on the neutral?

Yes. The TT 3000 can be installed behind an inverter and the secondary neutral grounded separately.

That creates a defined earth reference aboard and isolates the onboard system galvanically from the source. For a special boat configuration, check with us first.

Does the TT 3000 have inrush current limiting?

No. The TT 3000 has no soft-start.

The toroidal core draws a short, high current at switch-on. In fixed installations, size the upstream breaker accordingly — a C-curve breaker handles the cold-start inrush.

What connections does the TT 3000 have on input and output?

The input is a screw terminal; the output provides Schuko Type F, UK Type G, and a screw terminal.

A wiring schematic for the terminal assignment (L/N) ships with the unit and is also available for download in the documents section.

Our technology.

True galvanic isolation

The primary and secondary windings are physically separated; the output floats and has no conductive reference to the feeding 230V supply. An electrostatic screen on PE drains line interference to earth. In marine and stage setups this prevents earth loops and ground-loop hum and protects crew working on connected 230V equipment.

Screw terminal plus Schuko and UK sockets

The input is hardwired through a screw terminal; the output offers Schuko Type F, UK Type G, and a screw terminal in parallel. That lets you install the TT 3000 fixed on a wall or in a cabinet, or run it mobile on stage, with no adapters between the connection types.
