Single-phase voltage stabilizer AMPERE U 12-1/50 v2.1
Single-phase voltage stabilizer Ampere U 12-1/50 v2.1 (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 rated power of this model is 11 kW, which corresponds to the operating current of the circuit breaker of 50 A on it.
The features of this stabilizer include a double LED screen, a linear loading strip, the presence of electronic transit (bypass), a convenient location of the terminal block for connection on the back of the case, silent operation due to the use of thyristors as power switches.
Stabilizer Ampere U 12-1/50 v2.1 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 stabilizer Ampere U 12-1/50 v2.1 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.
