The TIS 300-124 is a TIS-series 300W 24VDC 12A DIN-rail Industrial Power Supply with switch mode. It is particularly designed for applications in industrial process control systems and with machine tools. Excellent specifications and high immunity against electrical disturbances guarantee reliable power for sensitive loads in rugged industrial environments. With the help of optional function modules specific requirements for system applications can be easily realized with a standard model. With the UDS module the power supplies can be extended to a perfect DC-UPS with automatic battery-backup. This function is very often required in applications where a time delayed shutdown of a system is necessary.
