A new family of power supplies expands the existing family of power supplies. Designed to efficiently convert ac to dc, these 24 V dc power supplies provide safety extra-low voltage (SELV),, according to EN 60950, and are suitable for the 24 V supply of according equipment and interface modules of the Turck series IM, IMS and IMC.
Offering wide-range input—between 90 and 260 V ac—the 24 V dc power supply can be used in diverse supply networks worldwide. Using an onboard potentiometer, the output voltage can be adjusted from 22.5 up to 28.5 V dc, and styles are available with an output current strength of 2.5, 5, 10 or 20 amps.
Featuring Class 1, Division 2 certification and rated IP20, the power supply was developed specifically to guarantee a dependable dc supply in the industrial environment. This highly efficient power supply can be run in parallel for applications requiring redundancy and includes overload protection of up to 150 percent.
For enhanced operator control and device status, a power relay is a reliable functional check, eliminating potential wire breakage or system malfunction. The device can also bypass power failures automatically, which allows the ac input to disappear for up to 30 ms without any effect on the output.
