Single-phase column variable transformers (economy winding, IP00)
Description
The REO variable column transformers supplement the REOVAR series for currents up to 1000 A for fine adjustment of the output voltage with constant current at the output.
The waveform of the sine wave is retained – so there are no EMC problems over the entire control range. All products in the series are supplied with UL-listed materials.
The REO design enables easy handling of the carbon roller and spindle and the copper bevel gear drive allows hysteresis-free adjustment of the output voltage even at high adjustment speeds of the drive motor. REO column actuators are therefore perfect for high power adjustment.
REO-column type variable transformers conform to EN 61558-2-14
