Automatic Transfer Switches for Power Distribution Systems: Microprocessor-Controlled ATS-C Transfer Switch System From Eaton

Eaton's Electrical Sector is launching the ATS-C transfer switch system, an automatic transfer switch system for power distribution systems. Mains supply failures can lead to critical situations, particularly in sensitive applications such as in hospitals, IT centers, commercial or infrastructure buildings, as well as in industrial manufacturing processes. If faults in the grid occur, the uninterrupted power supply (UPS) is a top priority in this case for the protection of persons and in order to secure service continuity. The new ATS-C microprocessor-controlled transfer switch system from Eaton ensures here the automatic or manual switching from the main power supply grid to the standby grid or generator, and thus ensures the security of the low-voltage supply at all times.

Eaton offers two versions of its new ATS-C automatic transfer switch controller: ATS-C 96 and ATS-C 144. The compact ATS-C 96 can be used in many applications for rated voltages up to 400 VAC. With cutout dimensions of 96 mm x 96 mm, the ATS-C 96 only requires a little space in the panel door. It also comes with an impressive range of practical functions such as various alarms, easy to program inputs and outputs, as well as an automatic test function with or without system transfer. The ATS-C 144 system offers additional functions and is suitable for applications with high rated voltages up to 690 VAC: This version also offers a real-time clock with event/statistics data as well as Modbus connectivity via an RS485 interface.

Both ATS-C transfer switch systems continuously monitor voltages, frequencies, phase sequences, battery voltage and several other parameters. The relevant limit values, including time settings can be parameterized and analyzed with the intuitively designed ATS-CSOFT software. This software can be run on all Windows PCs and is also used for commissioning and remote operation. However, users can also set and operate both ATS-C versions directly via the display and front operator panel. All operating states, alarms and parameters are visualized via (multi-lingual) LCD displays and LEDs. An event log shows the last 100 events with date and time.

The ATS-C product range is thus the logical extension of the accessory range of the NZM and IZM circuit-breaker series in order to increase the supply security of installation.
