Single-phase voltage stabilizer HERTZ U 36-1/32 v3.0


Single-phase voltage regulator Hertz is designed to work in electrical networks with voltage fluctuations from 150 to 260V. In this range, the device is guaranteed to deliver a voltage at the output within 220 ± 1-1.5%, which is ensured through the use of 36 stabilization steps. The Hertz model range in terms of power can be 5.5, 7, 9, 11, 14, 18, 22 and 27.5 kW, which corresponds to an operating current of 25, 32, 40, 50, 63, 80, 100 and 125A, respectively.

The features of this stabilizer include an informative LCD screen, event memory, the highest stabilization accuracy, plotting voltage and load, an interface in three languages, the presence of electronic transit (bypass), silent operation due to the use of triacs (thyristors) as power switches.

If it is necessary to obtain a voltage different from 220V in Hertz at the output of the stabilizer, there is a function of adjusting this value in the range of 200-230V.

The Hertz stabilizer has the ability to manually adjust the lower shutdown threshold (60-135V). This function is in demand for a load with high inrush currents, at startup of which a strong voltage drop and emergency shutdown of the stabilizer are possible. When this option is activated, the stabilizer will make it possible to start any engine or pump within a minute, even if the voltage drops to 60V in the network.

It is recommended to install and operate the Hertz stabilizer in dry and heated rooms. It is recommended to mount the wall in a vertical position (fans up), leaving 10-15 cm at the top and bottom for cooling. The connection is made to the existing wiring through the terminal block.
