Voltage Columns — column voltage regulators with rollers
Country: Italy · Model: Voltage Columns
Voltage Columns column voltage regulators are supplied as a unit for building powerful regulating machines and stabilisers. Current is taken off by rollers turning along the winding track, so the column works at powers where toroidal variators are no longer used.

Description
Each column has a magnetic core with a rod and a winding along which a motorised carriage moves the rollers. The roller rolls and does not slide, so the contact wears less and withstands large currents better than a flat brush. Several columns are assembled into one machine for a three-phase version or to increase power. The manufacturer builds its own high-power BST-TH series stabilisers on such units. Individual columns are bought by makers of switchgear and test benches, who assemble a regulator for their own project and their own control system.
How to choose
Columns are taken by integrators who design the cabinet, drive and automation themselves. If a ready-made unit is needed, it is simpler to order a Voltage Regulation Set up to 500 kVA with output ranges of 0–400 V, 0–500 V, 0–690 V or 400–600 V and an RVP-600 board. For laboratory tasks up to 50 kVA a toroidal VARIAC is enough, and the column VARIAC is supplied up to 500 kVA and more.

FAQ
What are column voltage regulators with rollers used for?
They are used as the basis for high-power regulating machines and stabilisers when a toroidal variator is no longer enough.
How does a column regulator differ from a toroidal variator?
VARIAC toroidal variators are made up to 50 kVA, while the column design with rollers is intended for machines up to 500 kVA and more.
Can a three-phase regulator be assembled from Voltage Columns?
Yes, columns are combined into a multi-column machine with a common drive, giving a three-phase version or higher power.
Is there a ready-made unit based on column regulators?
Yes, the Voltage Regulation Set is supplied up to 500 kVA, single- or three-phase, with a motorised drive and an RVP-600 board.
