Single-phase voltage stabilizer Ampere U 12-1/40 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 9 kW, which corresponds to an operating current of the circuit breaker of 40 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 triacs as power switches.
Stabilizer Ampere U 12-1/40 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 Ampere U 12-1/40 v2.1 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.
