Single-phase voltage stabilizer AMPERE U 12-1/50 v2.0


Single-phase voltage stabilizer “Ampere 12” (standard) is designed to operate in electrical networks with voltage fluctuations from 145 to 275V. In this range, the device is guaranteed to deliver a voltage at the output within 220 ± 3.5%, which is ensured through the use of 12 stabilization steps.

The lineup of all listed Amperes in terms of power can be 2.2, 3.5, 5.5, 7, 9, 11, 14 and 18 kW, which corresponds to an operating current of 10, 16, 25, 32, 40, 50, 63 and 80A, respectively.

The features of this stabilizer include silent operation due to the use of triacs (thyristors) as power switches and the presence of electronic transit (bypass).

The Ampere stabilizer in 12 steps 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 Ampere stabilizer in dry and heated rooms. It is recommended to mount the wall in a vertical position (fans upwards), leaving 10-15cm at the top and bottom for cooling. The connection is made to the existing wiring through the terminal block.
