High-precision voltage and current source

Automatic voltage regulator with separate windings, UI control and auto-reverse,
built into a 19-inch rack.

The AVRL single-phase voltage and current controllers are designed for use in laboratories, production control and test bays, where constant sinusoidal voltages from 3 to 230 V AC and currents up to 10 A, independent of mains fluctuations and load changes, are required. Multiple setpoint specification options enable flexible use for demanding measurement tasks.

The AVRL power supply units are equipped with an electromechanical control that stabilises the output voltage at the pre-selected value, independently of mains fluctuations or load changes. The devices are used for the continuous adjustment of alternating voltage and guarantee a stabilised output voltage of approx. +/- 0.1%.
