Qoltec Three-Phase Multiprotection AVR Voltage Regulator | 20 kVA | ±3% Accuracy | 3-Phase Servomotor | LCD | Expert Line

The Qoltec Three-Phase Multiprotection AVR belongs to the Expert Line of automatic voltage regulators: a dedicated device whose role is to keep the voltage delivered to your three-phase equipment within a controlled range. It is rated at 20 kVA, positioning it for substantial three-phase loads rather than small single-phase setups.

Regulation is handled by a three-phase servomotor system, which drives the correction of the output voltage continuously. Qoltec specifies an accuracy of ±3%, so the output is held close to the target level instead of drifting with the incoming supply. On top of that, the unit is described as a multiprotection AVR, meaning the design groups several protective functions together within a single chassis.

An integrated LCD display gives you a straightforward way to read and monitor the regulator's status during operation. Everything is built into the Expert Line format, aimed at users who want a specified three-phase stabilisation device with a clear accuracy figure and a readable front panel.
