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.
Regulation of Multiple-Output Models
Output 1 is under normal conditions regulated to Vo1 nom,

regardless of the output current. The voltage of the tracking
outputs 2 and 3 depends upon their load and the load on
output 1; see fig. 5 to 8.
