Variable Transformer RTE 230 V
Single-phase variable column-type transformers (auto windings, open, IP 00)
The REO column-type variable transformers complement the REOVAR series for currents up to 1000A with a fine-step adjustment of the output voltage at a constant current at the output.
The waveform of the sine wave is preserved – like that, EMC problems cannot occur over the entire operating range of 0 – 1000A. All products in the series come with UL – listed materials .
The REO construction enables easy handling of the carbon rolls and the spindle – the copper-bevel gear allows a hysteresis-free adjustment of the output voltage even at high adjustment speed of the drive motor. Thus REO variable column transformers are perfect for high performance adjustment .
REO-column type variable transformers conform to EN 61558-2-14
- High-precision adjustment (turn-to-turn voltage approx. 0.7 V)
- Generate no harmonic currents or voltages (clean sinusoidal output voltage, no harmonics)
- High overload capability for short time duty
- No EMC interference
