The automatic backup power supply device (ATS) E.NEXT e.pro.ats.4.250 is designed for automatic switching between the main and backup power sources in three-phase networks with a nominal voltage of 400 V AC. The model has a nominal current of 250 A and a four-pole design, allowing switching of the three phases and the neutral conductor (N).
The device uses a motorized load switch and supports automatic and manual control modes with three positions I–0–II. The built-in controller monitors the voltage of the power lines, allowing the setting of upper and lower voltage thresholds and the delay time when switching on. The first power input has priority, and if necessary, the load is transferred to the backup source.
The model has control signals for starting a generator, interaction with a fire alarm system and external signaling. An additional DC power supply to the controller is provided, and the mechanical indicator allows visual tracking of the switch position.
The device is suitable for electrical distribution boards, industrial installations and sites where automatic power supply backup is required.
