Schuntermann – Voltage management

Three-phase voltage regulator with separate windings for unbalanced load is designed for laboratory use, production control and test fields where sinusoidal voltages of 0 to 3 x 450/260 V AC and currents of up to 6 A are constantly required, independent of mains fluctuations and load changes. Multiple setpoint specification options enable flexible use for demanding measurement tasks.

The device is equipped with an electromechanical control which stabilises the output voltage to the preselected value regardless of mains fluctuations or load changes and guarantees a stabilised output voltage of approx. +/- 1%.
