Uninterruptible power supply is a critical factor for residential, commercial, and infrastructure facilities. That is why we present a video review of the SB-ATS-4-100 automatic transfer switch from UEC, a professional solution for three-phase input systems where power stability is of paramount importance.
The SB-ATS-4-100 is a four-pole ATS (3 phases + neutral) that provides fast and reliable switching between the main and backup power sources. In automatic mode, switching takes only 50 milliseconds, minimizing interruptions in the operation of equipment and critical systems.
The device supports both automatic and manual control modes, which is convenient for maintenance and non-standard operating scenarios. Built-in voltage control provides an additional level of protection — if the voltage drops below 175 V or exceeds 260 V, the control circuit is automatically disconnected to maintain the device's operability.
The UEC SB-ATS-4-100 ATS is rated for a nominal current of 100 A and a voltage of 400 V. The IP30 protection rating allows the device to be used in indoor distribution boards. It can be mounted on a DIN rail or on a mounting panel with screws.
It is important to note that for the ATS to function correctly, the power of the backup power source (e.g., generator or inverter) must be at least 3 kW. It is also necessary to provide additional overcurrent protection devices (circuit breakers), since the switch itself does not perform protection functions in emergency modes.
Watch the video review to learn more about the design, connection, and operation of the UEC SB-ATS-4-100 automatic backup power switch. It is a reliable solution for those who value stability, safety, and control over their power supply.
