Bronson VC 5000 — Variac 0–300 V

Variable transformer for stationary test benches. 0–300 V stepless, up to 5000 W / 20 A, screw-terminal connection.

Up to 5000 W / 20 A for continuous test use

The Variac delivers up to 5000 W at 20 A — sized for high-draw loads on stationary test benches and industrial test environments.

230 V input, 0–300 V stepless output

From a 220–240 V line, the adjustable voltage regulator sets the output steplessly from 0 to 300 V — for reproducible voltage profiles in load tests and commissioning.

Screw-terminal connection up to 20 A

Input and output run through screw terminals rated to 20 A — for fixed installations, fixtures, and switchboard integration rather than plug-in swaps.

Frequently asked questions

Is the VC 5000 connected via fixed screw terminals?

Yes. Input and output are screw terminals rated to 20 A, without a Schuko socket.

The VC 5000 is built for fixed installation in fixtures, test benches, and switchboards. Wire it in directly rather than swapping devices by plug.

Does the VC 5000 deliver the full 5000 W at 100 V?

No. The output current is limited to 20 A, so at 100 V that is about 2000 W.

Because the current is fixed-capped, usable power scales with voltage: the full 5000 W is available near the top of the range. Plan loads by current, not only by the 5000 W nameplate.

Is the VC 5000 suitable for stationary continuous test benches?

Yes. With 5000 W at 20 A, the VC 5000 is sized for laboratory and industrial test benches in continuous use.

Its fixed screw-terminal wiring and 17.5 kg build suit a permanent bench position for load tests and commissioning runs.

When should I choose the VC 5000 over the VC 3000?

Choose the VC 5000 from higher continuous loads: 5000 W at 20 A versus 3000 W at 12 A on the VC 3000.

The VC 5000 connects via screw terminals for fixed installation and weighs 17.5 kg for a stationary bench; the VC 3000 offers a Schuko output for changing test objects.

Our technology.

Screw terminals for fixed installation

Input and output on the VC 5000 use screw terminals rated to 20 A / 5000 W. This suits fixed wiring in fixtures, test benches, and switchboards — a permanent connection for continuous operation instead of plug-in swaps.

Toroidal core with copper winding

The VC 5000 runs on a toroidal core with copper winding, sized for 5000 W at 20 A. The design holds efficiency at ≥ 90 % and keeps loss heat low under continuous load — suited to stationary test benches.
