Mode At heavy overloads (when output voltage falls below 13V), 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 Figure 6-3
***) Discharge current of output capacitors is not included.
****) 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 28.5V (in “single use” mode).
