*) This is the maximum output voltage which can occur at the clockwise end position of the potentiometer due to tolerances. It is not
guaranteed value which can be achieved. The typical value is about 15.8V (in “single use” mode).

At heavy overloads (when output voltage falls below 6V), the power supply delivers continuous output current for 2s. After this, the
output is switched off for approx. 18s before a new start attempt is automatically performed. This cycle is repeated as long as the
overload exists. If the overload has been cleared, the device will operate normally. See Fig. 6-3.
***) Discharge current of output capacitors is not included.
