All outputs from the units are protected against overload and short circuits by electronic ‘fuses’. These operate independently so that, if one output trips, the remaining three outputs are unaffected. The tripping current is configurable by the user, and the ‘fuses’ are unaffected by inrush currents such as those produced when switching capacitive loads. In addition, the ‘fuses’ can be easily reset, either locally or remotely using the IO-Link connection if equipped.
Pushbuttons on the front of the power supplies allow the output voltage to be fine-tuned to suit specific applications. They also permit adjustment of the electronic ‘fuse’ operating current and allow resetting of the ‘fuse’ after a trip. Colour-coded LED indicators provide a comprehensive overview of the power supply status.
