Unique Selling Point


  • Closely stepped adjusting of output voltages
  • Low-loss cores
  • Vacuum impregnated windings
  • Windings virtually maintenance free
  • UL-listed materials
  • Available in IP 00 and IP 20
  • Wide range of accessories

Description


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

RTE 230 V

Single-phase variable column-type transformers (auto windings, open, IP 00)

Overload factor

Faktor kK relative to operation time t.

 

Maintenance:

Contact carbon rolls are furnished with hard-silvered axes. Threaded spindles run  in self-lubricating bearings and are almost maintenance-free.

Seized or worn carbon rolls must be replaced immediately.

From time to time the contact surfaces of the windings should be cleaned with a stiff brush to remove adhered dirt (dust and carbon abrasion).

Maintenance manual on request.
