Output Characteristic and Protection
Each output is protected by a suppressor diode, which under a
worst case condition may become a short circuit. The
suppressor diodes are not designed to withstand externally
applied overvoltages. Overload at any of the outputs will cause
a shutdown of all outputs. A red LED indicates the overload
condition of the respective output.
