The Easy Front Key Setting interface on the 7-segment LED display provides a clear and intuitive way to monitor and adjust input and output values, along with various parameters. This advanced system features a Slow-Up and Slow-Down function to smoothly transition between settings, enhancing user control. The universal power supply supports a wide voltage range of 100 to 240V AC, and the automatic frequency discerning function accommodates both 50 and 60Hz, ensuring reliable operation in diverse environments. Data communication is available as an option, facilitating seamless integration with other systems. For added functionality, it includes an optional current detection and alarm output feature, which ensures timely notifications for any deviations.
