    5.2 Output-side connection Output-side connection At its output, the SITOP PSU100S power supply provides an isolated (= non-grounded) SELV output voltage (Safety Extra Low Voltage). The output of the power supply is no-load, overload, and short-circuit proof. If an overload occurs, the electronic current limitation limits the output current to a maximum value (refer to chapter Technical data (Page 39)).
