Voltage stabilizer Eleks Amper U 12-1/40 v2.1

The single-phase voltage stabilizer Ampere U 12-1/40 v2.1 (standard) is designed for operation in electrical networks with voltage fluctuations from 145 to 275V. In this range, the device is guaranteed to produce an output voltage within 220±3.5%, which is ensured by using 12 stabilization stages. The rated power of this model is 9 kW, which corresponds to the operating current of the 40 A circuit breaker on it.

The features of this stabilizer include a dual LED screen, a linear loading strip, the presence of an electronic transit (bypass), a convenient location of the terminal block for connection on the rear of the case, and silent operation due to the use of triacs as power keys.

The Ampere U 12-1/40 v2.1 stabilizer has the ability to manually adjust the lower shutdown threshold (60-135V). This feature is useful for loads with high inrush currents, which can cause a significant voltage drop and emergency shutdown of the stabilizer upon startup. When this option is activated, the stabilizer will start any motor 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 wall-mount it vertically (with the fans facing up), leaving 10-15 cm of space above and below for cooling. Connection is made to existing wiring via a terminal block.
